Congratulations! You started on the same path I did 30 years ago and learned a few things along the way! If I may give you an advice, if you want to rework the crossover with better parts (air core inductors and Mylar capacitors) you would discover that the midrange and tweeter sound will improve. Also, Polyfill is not always the best material for damping speakers. Some acoustic foam around 12 millimeters thick could provide a better performance. To check if that works well, modify one speaker at a time and do a A-B comparison using a monophonic recording or pink noise. It will cost you more than a few dollars, but the reward could be amazing!
@@rickcorel5154 I'm not sure if it will work because it hardens and its acoustical property are almost the same as wood or metal. Whatever you use must be 'spongy' or fibrous in nature for sound waves to be absorb and not radiate back in the enclosure. Foam of polyfill are the most used but you may try other products with sound proofing properties. Good luck!
All right I said before that I will do the similar polyfill coating of the inside. And I did. Not as same as told in the you tube video.I cut the polyfill pieces much more bigger, I used much more polyfill and covered much more inside area. I also used the sponges already yamaha put. I covered the crossover circuit too. I put so much sguuezed polyfill in the medium driver's case. I didn't make anything to the tweeters. Ok. The basses became deeper as it comes from the back, you feel much more bass in your abdomenal innards. Much more improvement achieved in the mids. Mids became more clearer, less distortion. Thanks to the polyfill, thanks to my workmanship and struggle shame to the lazy Yamaha!
I am waiting for my ns-777's to arrive. I don't want the feet sticking out as well. I am hoping to mount them inwards instead of outwards. I also ordered yamaha powered subwoofer so no need to get into the guts. Thanks for sharing, definitely worth a like.
Polyfill adhered to the insides has no effect on standing waves, since that's where the pressure is highest but the speed of air approaches zero. For damping the actual enclosure panel's modes you need heavy mats, not a sponge. Enclosure panels look flimsy, so if you put your ear against it you will realize that actually the box emits as much sound as the speaker itself, which is not synonymous with HiFi. As the diaphragm moves, the box wants to move in the opposite direction, cannon and shell principle.That's why you want to anchor the speakers on spikes - to make it impossible for it to move. Spray the bead or your finger with window cleaner - it won't stick and you'll have a smooth joint, that you didn't really need in the first place. Why ? Because they are ported, hence the air follows the path of least resistance and flows through the resonator, well, below and above the tuning frequency, but that's beyond the scope of a short comment. In simple terms, no air will be forced through tiny gaps as it flows through the port easily. This also explains why they didn't bother to seal the back of the tweeter, although an airtight cup would normally be there with the detriment of increasing tweeter fundamental (Cms x Mms) resonance frequency. Crossover looks dirt cheap, and so does the speaker actually, lack of low frequency extension is a function of efficiency, they were made to play loud, not deep, end of.
....these are very heavy speakers..unit is like 50kgs. Box is made out of thick panels. Yes,..base is not enough. Need a sub...with a sub its a beautiful sound unit. I have no complains,...Yes ..it can be played very loud...without distortion.
@@CT-vl3iu NS777's weight is listed as 24kG each, which considering its size can hardly be described as heavy, rather standard. Not sure what you mean by base, but in terms of low frequency extension, or bass, there is a trade-off between LFE extension and efficiency inherent in every design, with balance tipped towards level rather than extension here. Adding a subwoofer to compensate for poor performance of main speakers in other areas seems bizarre to be honest.
@@CT-vl3iu Absolutely, I have added a sub as well to my speakers; two Peerless XLS10 drivers in push pull configuration firing into a 20L sealed enclosure with a dedicated, seaparately housed amplifier. It's terribly overdamped with the Qtc of 0.35 thus falling into the range of infinite baffle rather than classical acoustic suspension arrangement. Fc is around 35Hz and the frequency response has a -3dB point at around 90Hz. I've accomodated a low q compensation network tuned to 22Hz to linearize it and ended up with a flat -3dB curve between 15 and 45Hz. The rest of the low frequency range is covered by the speakers however with two differentialy tuned 6" woofers in individual sealed enclosures. The efficiency as a whole is only around 83dB/1W/1m, but that's the price for having a flat response with such an arrangement.
From all yamaha floor speakers can to say NS-F160 its clear sound plus good strong and clear bass,and inside can to say its empty none any foams,some made just to look nice and crazy prise,still pay for name,good luck👍🏼
I just bought some nsf160 towers second hand, and they have foam in them down the bottom half in the middle. do yours have foam in them at all? from factory?
I bought my 2 NS-777 on craigslist 9 years ago for like $150. Great speakers. The only thing, sun was on one of the speakers and laminate shrunk/distorted and came off on a side.

Best part is: 11:00 :-D These YAMIS deserve much much more, since they are too bright sounding with those Nippon elcos on the crossovers at all, so change them with any type of MKPs, and listen! Note however, that the internal Monster brand cabling is good enough, just the box needs a little more reinforcements in the bass section, with some horizontal bracings, and they can be quite musical speakers at the end of the day for sure!
I just bought these speakers I thing they sound Great the bass is large maybe a bit boomy depending on what's played. my opion and experience not saying I'm correct ,why wouldn't Yamaha not seal there speakers on the corners, if they leaked air you would feel the air escaping from the corners when turned up loud if you can't feel air escaping I dont see the point putting filler in all the corners maybe for re enforcement that's about it.A good test seal the port with a tennis ball and turn it up and see if you feel air escaping if you don't then the box is sealed. I know a leaking box does affect the sound ported or sealed, sealing it makes a big difference from my experience with building subwoofer boxes for cars.adding more material to the midrange I believe your changing the volume of air it was intended for and adding all the insulation inside changes the acoustics of the speaker and will alter the sound .I think maybe better quality backing might help like closed cell foam behind the speakers alone . Just my opinion but I guess ears will tell the end result.
My viewer sent me such speakers for an upgrade. I'll be in my studio literally in a week. I will definitely upload the video to my channel. I will also make a kit for selling a new filter. I invite everyone who has such speakers !!!
Very good. I will attempt this myself with my NS-555's. There is indeed a lack of low end. Hopefully the poly-fill will result in sound production as if the enclosure were larger in size.
Good point. I do have them paired with a YST-SW215 8” downfiring. However, I’ll give the polyfill a go if the bass response improvement is subtle yet noticeable. I just upgraded to the NS-555’s from a pair of NS-50F’s which actually had a bit more low end punch.
Hi Man, need your advise, Im about to get a pair NS777, but maybe the NS555 are the same great quality sound, just that NS777 gived more power. I got my ns333 and Im in love of its vivid sound that is whst i want. So, do you reccomend NS555 ?? Regards !!
@@robertomanodepiedranomas4283 Hey mate. Neither speaker is known for good bass reproduction. I sold my NS555's early this year and replaced them with some 1975 Sansui SP1200's. The NS555's had reasonable mid range and highs, but lacked bass. I'd imagine the NS777's would go a tiny bit deeper, but still not much. You'd need a subwoofer if you wanted that low punch. You can't go wrong with either model but I'd probably recommend NS777 if you have the space.
@@HybridBell Good to read your comments. I do agree with thw low issues. And let me tell you thats why i own a subwoofer SW300, and soun great all together. For what you explain now Im sure Im in good direction. But is exactly matter of place (room) that it may be be the NS555. Sorry but let me ask you another question. with the subwoofer i have, youd consider eighter both could be the same ? Or yiu wold think that even do NS777 sond better with the subwoofer. Thanks Man.
@@robertomanodepiedranomas4283 Both NS555 and NS777 would sound pretty similar. In terms of internals, the 555 and 777 are pretty much the same apart from the woofer size and minor crossover tweaks. Since I haven't owned the NS777, I couldn't tell you. My best assumption is they'd still sound pretty similar and lack low bass like many NS series Yamaha speakers. NS-SW300 is a great subwoofer and I think it will complement your speakers perfectly regardless if you choose 555 or 777. If size matters, I'd go NS555 since the 777's are quite big speakers. Since the speakers will only be handling the midbass - high frequency range, the NS555 would be fine since you are using a subwoofer to produce the lows.
Dude, you need to upgrade the crossovers. Check my audio clip after crossover upgrade. It will do more than this filling issue. Also bass reflex tube needs to be longer. Then you get the lowest bassnotes out from the yamahas.
The reason why there's only so little amount of acoustic damping is they possibly wanted it that way. And the sealant on that opening at the back of the tweeter will not be good for air circulation and possibly damage the tweeter because of overheating etc. Let professionals do the job. May be more costly, but trial and error can be too.
I just got some of these second hand for a steal! They sound pretty good but they show up that my class D amplifier isn't the best for driving such speakers. I think they will sound much fuller with a decent amp when I can afford one. Sound ok though, just sound a little dull with the current amp (Aiyima A07). I'm thinking of getting a second Aiyima and running my old speakers just to crisp things up a bit.
Единственный косяк в этих колонках это среднечастотный динамик его пластмассовый корпус даёт сильный призвук поэтому его нужно за демпфировать полностью вибропластом и внутрь уже положить немного синтепона Ну тогда он зазвучит просто супер!!!!!!
The question would be is it worth it with the sub? I have an active sub and also have bi amped the front. I have four of the same spekers back and front. Could you give me advice?
Interesting, I just uploaded a video where I found 2 boxes of ns-333's at the dump. I might be getting a set of these speakers at some stage to complement them. But I already have subs so probably won't do the change. Interesting to watch though 👍
Why not, polyfill can prevent mid and treble coming out of the port and reflect on the wall behind the speakers. Resonance frequency may be increased a bit so it will produce louder bass (at the cost of less bass extension). These speakers extend to 30Hz by specs and most music do not have frequencies around 30Hz anyway.
Its not light, if you have to much middle frequently use equalizer, or use somthing small like synthetic rubber. Air volume ist most importan in this type speakers. Remember about corect position speakers and listener in the room.
Tip to save the time, all of this is wonderful, but the key is just removing the two pieces of dark grey foam - one in each. Accessible from just temporarily removing the bottom woofer, removes damping and gives more bass, it was this which contributed to the improvement in low end response.

Should have glued something soft to the mid-range speakers around the perimeter of the cup It necessary to glue something soft to the midrange speakers around the perimeter of the cup.
Bel lavoro... è cambiato tanto il suono ? Secondo me dovevi cambiare anche il filtro crossover. E' vergognoso che Yamaha faccia un assemblaggio così schifoso.... bravo
Фазоинвертор сзади.не имею знаний но от стены расстояние надо соблюсти .я думал по кусочку синтепона прикрепить сзади динамиков а тут чел такого наворотил.сзади пищалок вентиляцию заклеил.я вообще в ахуе.
Check where these speakers are made. If they are made somewhere else than Japan, then they are crap, but if they are made in Japan, they should sound good.
А вот кроссовер я буквально через неделю буду апгрейдитЬ: зритель выслал мне такие колонки на апгрейд. Так что будет видео ролик про это на моем канале.
What a Shame to yamaha... In my country (in Turkey) now they are sold at circa 1000 euro price and the yamaha was too lazy to even coat the inside of the tower speakers with polyfill!!! shame shame shame... and I strongly condemn Yamaha's this shame. I have also these speakers and I am gonna to do this same polyfill coating for them. I will share the results as soon as I have finished the job and make the comparison A - B speakers test. Thank you ver very much for this video and the youtube facility. the world wouldn't be the same after this internet revolution!!!
Друг, добавляя звукопоглощающий материал вы меняете резонансную частоту корпуса и это может иметь очень сильные негативные последствия. Нет никакого позора. Почитайте пару книг об акустике. Дадеко не все компании вообще применяют звукопоглотитесь.
Эта акустика для кинотеатра... А если уж затеялись усовершенствовать ,то динамики надо было сажать на резиновые прокладки ? Не ставьте на них ничего. Эффект улучшения чисто психологический , но если хозяину так лучше , значит он прав ! Молодчина .
Hi I will build a 7.2 system with 2 subwoofers. the speakers i want are Taga Harmony TAV-807F Pair of Hi-Fi Floor Speakers 180W 3 Ways and for center channel side and rear sound the same Taga Harmony TAV-807F. subwoofer I don't know how many watts and inches, I will have to ask what is better after TAV 807F. Amplifier. Yamaha RX-A2A Home Cinema 4K/8K 7.2 Channel Amplifier 125W/8Ω 160W/6Ω with HDR and Dolby Atmos Black. I choose this one because it has 160 watts at 6 Ω. the colour of the speaker is probably white or brown. I am exactly 3000 euros.then I want a 4ķ bluray player and projector and im ready. ( now I'm thinking if the yamaha Yamaha NS-777 sounds better from Taga Harmony TAV-807F or about the same level ) it's hard to decide
These are ported and as so do not need filled everywhere with foam filler, in fact you just detuned your speakers, you want the air to move around in a ported enclosure, I wasn't aware these speakers were ported until mine arrived today, I have them hooked up to a Kenwood KA-80 Stereo amp and the bass is beautiful, I think you just have a cheap Amplifier or poor hearing 🤷
Mister, isolate the upper section from the bass section. Get rid of the midrange woofer from the cap. And make the back of the wall of the upper compartment open, let the midrange speaker be in the open air. Install a rectangular plastic grille on top of the case so that it hides the hole.
I have read some comments written about the comparison of NS 777 and NS 555's. How could they say that they have the similar sounds? NS777's have two 8" woofers but the NS555's, on the contrary, 6". of coyrse the the basses would be weakernin NS55's...
The problem is not the spekers... the av reciver its the problem... problema non sono le casse.. ho cambiatto il vechio amp (anni 70-80) per un av reciver, gli bassi sono spariti. Con il vechio amp spacavo le finestre... con il av reciver da yamaha rxd485 no ho piu gli bassi..
Use stereo amplifier u will get better bass, dont except better bass from av recivers coz they dont give better bass also av recivers concept only movie not music so u use good stereo amp, no need subwoofer.
Вот значит как. Выходит японцы разрабы в Ямахе дураки, и не сделали на заводе того, что у себя в гараже Вася доделал. Давайте тогда и в мотиках Ямаха чего-нибудь доделаем, карбюратор там.
По моему люди (чел в видео) просто не понимают что делают. Если бы надо было то инженеры бы так и сделали сразу. Даже в колонках которые стоят тысячи евро за штуку не всегда есть такая изоляции внутри. И на то есть причины. После такой переделки они просто звучат по другому. А человек решает для себя что это лучше чем было. Чтоб действительно выявить лучше\хуже, то надо производить замеры до и после. Но не ухом а прибором.
Не маловажым является правильная акустика помещения в которой стоят колонки. Даже средние колонки начнут звучать лучше если комната соответственно подготовлена. Даже положение колонок играет роль. В видео колонки стоят чуть ли не к сетене впритык. Это просто п****ц!
Хорошая акустика за свои деньги, кто бы что не говорил. Владею 555, перебрал кучу ресиверов, ни с одним прям музыкально они не заиграли, а вот топовыми двух канальными усилителями просто песня, прям все жанры поют. Очень сильно влияет помещение на качество звука, практически 50% звука это комната. А на видео они стоят с полным нарушением по требованию к установке. Так ни одна акустика нормально не заиграет. Никогда не понимал людей, которые о качестве звука судят глазами. По тому, что видят внутри. Это не блестит, мол это не будет играть, не понимая физических принципов звука и тока, не зная закона ома и уж тем более, как устроен фильтр в акустике. Инженеры далеко не дураки и создали вполне качественный продукт в бюджетном сегменте HI-FI. Просто не у каждого покупателя хватает ума подобрать правильный усилитель и организовать комнату и расположение акустики.
Заполняет синтепоном, правильно. Лучше скомбинировать синтепон, войлок на заднюю стенку и акустическую вату под ВЧ. Этот пластмассовый кожух СЧ я бы вообще выкинул. Если и нужна перегородка, то на крайний случай из ДСП, ее тоже обложить синтепоном. Производитель, как правило, не сильно заморачивается, так-что проводка и заполнение корпусов - дело каждого. Это ручная работа, в пром. масштабах слишком дорогая. Колонки были бы гораздо дороже. Но, вобщем, чем дороже колонка, тем больше там наполнителя.
That hole for the tweeter is for air to escape. Likely pressure and cooling

Единственный косяк в этих колонках это среднечастотный динамик его пластмассовый корпус даёт сильный призвук поэтому его нужно за демпфировать полностью вибропластом и внутрь уже положить немного синтепона Ну тогда он зазвучит просто супер!!!!!!
я так и сделал,а внутренее деммпифирование колонки не к чему паралон еще нужно верхний выкинуть!!!!!!!!!!
лучше выбросить пластмасс и перегородить отдельный отсек?.. Для СЧ?
The question would be is it worth it with the sub? I have an active sub and also have bi amped the front. I have four of the same spekers back and front. Could you give me advice?
In the Russian-language TH-cam there is such a channel Stalker that made a complete diagnosis of these speakers and they turn out to be very good
Ну да, на заводе Ямаха *дураки* же работают, не задемфировали
if you left 30 cm from the wall and put little foam around the speakers before you put is better no air get out from around the speaker!!!!!!
Hi man. Just change crossovers on most qualified with nonpolar capacitors , and tweeters ,like as it did i'am. After ,your sounds will much better! :)
Interesting, I just uploaded a video where I found 2 boxes of ns-333's at the dump. I might be getting a set of these speakers at some stage to complement them. But I already have subs so probably won't do the change. Interesting to watch though 👍
Its open box, you dont need proofing. You take off volume and hight change rezonans box
Why not, polyfill can prevent mid and treble coming out of the port and reflect on the wall behind the speakers. Resonance frequency may be increased a bit so it will produce louder bass (at the cost of less bass extension). These speakers extend to 30Hz by specs and most music do not have frequencies around 30Hz anyway.
Its not light, if you have to much middle frequently use equalizer, or use somthing small like synthetic rubber. Air volume ist most importan in this type speakers. Remember about corect position speakers and listener in the room.
Tip to save the time, all of this is wonderful, but the key is just removing the two pieces of dark grey foam - one in each. Accessible from just temporarily removing the bottom woofer, removes damping and gives more bass, it was this which contributed to the improvement in low end response.
Вы не сделали главное - вы не заменили конденсаторы кроссовера. Если их заменить -вук СЧ и ВЧ - улучшается СУЩЕСТВЕННО. Разборчивать ВЧ становится на уровне Хай Энд.
Good job 👍...
better capcitor have you good results
I was going to buy and i wont for sure thnx bro !!
Should have glued something soft to the mid-range speakers around the perimeter of the cup
It necessary to glue something soft to the midrange speakers around the perimeter of the cup.
And at the metal reception I came across a box from 1 satellite from NS-333 only without a large speaker only High-frequency
тоже тмею такой комплект ) вот тоже бы надо заняться доработками)

Bel lavoro... è cambiato tanto il suono ? Secondo me dovevi cambiare anche il filtro crossover. E' vergognoso che Yamaha faccia un assemblaggio così schifoso.... bravo
Подскажите у кто-нибудь сталкивался . Начала отклеиваться облицовка Думаю как востоновить и на что лутьше подклеить
Фазоинвертор сзади.не имею знаний но от стены расстояние надо соблюсти .я думал по кусочку синтепона прикрепить сзади динамиков а тут чел такого наворотил.сзади пищалок вентиляцию заклеил.я вообще в ахуе.
Он просто еще молод глуп и не ведает что творит!
🔥
Ilmselt tead sa rohkem kui yamaha insenerid.
Check where these speakers are made. If they are made somewhere else than Japan, then they are crap, but if they are made in Japan, they should sound good.
кроссовер просто шедевр. за демпфировал хорошо но кроссовер это жалкое зрелище.
А вот кроссовер я буквально через неделю буду апгрейдитЬ: зритель выслал мне такие колонки на апгрейд. Так что будет видео ролик про это на моем канале.
Rispondi... è cambiato il suono ? Grazie
What a Shame to yamaha... In my country (in Turkey) now they are sold at circa 1000 euro price and the yamaha was too lazy to even coat the inside of the tower speakers with polyfill!!! shame shame shame... and I strongly condemn Yamaha's this shame. I have also these speakers and I am gonna to do this same polyfill coating for them. I will share the results as soon as I have finished the job and make the comparison A - B speakers test. Thank you ver very much for this video and the youtube facility. the world wouldn't be the same after this internet revolution!!!
Друг, добавляя звукопоглощающий материал вы меняете резонансную частоту корпуса и это может иметь очень сильные негативные последствия. Нет никакого позора. Почитайте пару книг об акустике. Дадеко не все компании вообще применяют звукопоглотитесь.
Эта акустика для кинотеатра... А если уж затеялись усовершенствовать ,то динамики надо было сажать на резиновые прокладки ? Не ставьте на них ничего. Эффект улучшения чисто психологический , но если хозяину так лучше , значит он прав ! Молодчина .
Hi
I will build a 7.2 system with 2 subwoofers. the speakers i want are Taga Harmony TAV-807F Pair of Hi-Fi Floor Speakers 180W 3 Ways and for center channel side and rear sound the same Taga Harmony TAV-807F. subwoofer I don't know how many watts and inches, I will have to ask what is better after TAV 807F.
Amplifier. Yamaha RX-A2A Home Cinema 4K/8K 7.2 Channel Amplifier 125W/8Ω 160W/6Ω with HDR and Dolby Atmos Black. I choose this one because it has 160 watts at 6 Ω.
the colour of the speaker is probably white or brown. I am exactly 3000 euros.then I want a 4ķ bluray player and projector and im ready.
( now I'm thinking if the yamaha Yamaha NS-777 sounds better from Taga Harmony TAV-807F or about the same level ) it's hard to decide
These are ported and as so do not need filled everywhere with foam filler, in fact you just detuned your speakers, you want the air to move around in a ported enclosure, I wasn't aware these speakers were ported until mine arrived today, I have them hooked up to a Kenwood KA-80 Stereo amp and the bass is beautiful, I think you just have a cheap Amplifier or poor hearing 🤷
Jak to Yamaha na zewnątrz ładnie a w środku tandetne głośniki trzeba było wymienić głośniki tylko na taką samą moc
На какие поменяли?
You will try to Nakamichi AV 10 amplifier
Your speaker tower is in wrong position, its tooo close to the wall
Como veo al final del video, los parlantes estan mal ubicados, tenes que separarlos de la pared y las esquinas al menos 20cm...
Mister, isolate the upper section from the bass section. Get rid of the midrange woofer from the cap. And make the back of the wall of the upper compartment open, let the midrange speaker be in the open air. Install a rectangular plastic grille on top of the case so that it hides the hole.
Your stereo amp ???
Bass was low with 4 8 inch woofers?!
Really?
Io avrei cambiato anche quei condensatori del crossover scadenti, per una migliore qualità del suono.
What did you use to replace the feet?
Just regular furniture feets. But i reccomend rubber feet. Better vibration isolation.
Good video, bad speakers!
low quality crossover speaker housing and assembly , you get what you pay for.
Let's change those el-cheapo caps and this baby will start to sing for real! ;)
I have read some comments written about the comparison of NS 777 and NS 555's. How could they say that they have the similar sounds? NS777's have two 8" woofers but the NS555's, on the contrary, 6". of coyrse the the basses would be weakernin NS55's...
you don't need to do it in the mid-range speaker.
The problem is not the spekers... the av reciver its the problem... problema non sono le casse.. ho cambiatto il vechio amp (anni 70-80) per un av reciver, gli bassi sono spariti. Con il vechio amp spacavo le finestre... con il av reciver da yamaha rxd485 no ho piu gli bassi..
the baby 🤣
Use stereo amplifier u will get better bass, dont except better bass from av recivers coz they dont give better bass also av recivers concept only movie not music so u use good stereo amp, no need subwoofer.
И как теперь их покупать?
Не глядя)
Я выбирал между Ямахой 777 и Магнат 2002, выбрал Магнат, звучит натурально с хорошим глубоким басом .
Это комод, трюмо или шкафчик???
и звук координально поменялся ахахахахаха😆
Вот значит как. Выходит японцы разрабы в Ямахе дураки, и не сделали на заводе того, что у себя в гараже Вася доделал. Давайте тогда и в мотиках Ямаха чего-нибудь доделаем, карбюратор там.
это китай-колхоз-строй-разве не заметили? Дешевый фильтр и динамики...
Японцы высшего класса-А.С=капитально проклеивают корпуса войлоком...
японские это были до 1990, а астольное шлак
Я в шоке! Отдай 50000 рублей и еще доробатывать!?!?!?
По моему люди (чел в видео) просто не понимают что делают. Если бы надо было то инженеры бы так и сделали сразу. Даже в колонках которые стоят тысячи евро за штуку не всегда есть такая изоляции внутри. И на то есть причины. После такой переделки они просто звучат по другому. А человек решает для себя что это лучше чем было. Чтоб действительно выявить лучше\хуже, то надо производить замеры до и после. Но не ухом а прибором.
Не маловажым является правильная акустика помещения в которой стоят колонки. Даже средние колонки начнут звучать лучше если комната соответственно подготовлена. Даже положение колонок играет роль. В видео колонки стоят чуть ли не к сетене впритык. Это просто п****ц!
Хорошая акустика за свои деньги, кто бы что не говорил. Владею 555, перебрал кучу ресиверов, ни с одним прям музыкально они не заиграли, а вот топовыми двух канальными усилителями просто песня, прям все жанры поют. Очень сильно влияет помещение на качество звука, практически 50% звука это комната. А на видео они стоят с полным нарушением по требованию к установке. Так ни одна акустика нормально не заиграет. Никогда не понимал людей, которые о качестве звука судят глазами. По тому, что видят внутри. Это не блестит, мол это не будет играть, не понимая физических принципов звука и тока, не зная закона ома и уж тем более, как устроен фильтр в акустике. Инженеры далеко не дураки и создали вполне качественный продукт в бюджетном сегменте HI-FI. Просто не у каждого покупателя хватает ума подобрать правильный усилитель и организовать комнату и расположение акустики.
Заполняет синтепоном, правильно. Лучше скомбинировать синтепон, войлок на заднюю стенку и акустическую вату под ВЧ. Этот пластмассовый кожух СЧ я бы вообще выкинул. Если и нужна перегородка, то на крайний случай из ДСП, ее тоже обложить синтепоном. Производитель, как правило, не сильно заморачивается, так-что проводка и заполнение корпусов - дело каждого. Это ручная работа, в пром. масштабах слишком дорогая. Колонки были бы гораздо дороже. Но, вобщем, чем дороже колонка, тем больше там наполнителя.
That crossover is a joke
I could’ve built a house with that amount of work 🥴🥴🥴 maybe just buy slightly better speakers
Allready buyed. Old video and mod. But yes, better is buy new speaker.
колхоз
Они не стоят столько денег.
К сожалению это часть интерьера а не акустической системы.
