Thank you for showing the speaker from the inside. I like such films the most, and thanks to them, users do not have to disassembly their subwoofers. A large magnet, the speaker looks good. How do you rate this subwoofer?
Go to mark: 3:19 top left circuit, Do you see the 820 Ohm fried resistor? I do. Common with this sub amp. It is only a 3Watt. Replace it with a 10watt and add wires to move it to a heat sink.
Yes looks god, better than Focal JMlab 700s series. That Focal sub have terrible thin pressboard, the quality of the external material is below every criticism, but sounds normal.
I honestly really like their designs even tho they dont get super low they got a better performance above 35hz compared to svs. When I changed my sub to svs and later ultimax I kinda missed smaller excursion driver for that reason
It's unfortunate that Klipsch went with a cheaper 2 magnet woofer rather than one large magnet which definitely makes a difference. Regardless though, I'm a Klipsch Sound System owner too.
Multiple, stacked magnets are no more or less effective than one large one. Multiple small round magnets arranged in a donut shape (Focal, Epique), are especially effective when using rare earth neodymium, samarium cobalt, etc.. This woofer is actually surprisingly well built, with an extended length 2 inch diameter voice coil. The magnet is stacked to give it depth allowing it to control the extra excursion. It just isn’t pretty, doesn’t need to be. There’s a specific requirement depending on the design and construction. To a great, almost absolute degree, the size is determined by the application. There are a lot of really BIG magnet speakers on the market that sound like shiz… Check out the Morel line of large voice coil diameter, neodymium configurations that simply bury larger, impressive looking, inferiorsounding subs. For the most part, especially in audio, you get what you pay for.
@@steveschwartz9421 yup motor force calculations are different and it's also based on the grade of ferrite and neo along with how the motor is magnetized to get the BL specs of its TS parameters along with how it interacts with the voice coils and soft parts. Its a big balancing act between cone control, excursion, efficiency etc.. bigger magnets with bigger voice coils and stiffer suspension, you can throw a lot of power to before it wakes up and can have much higher capabilities even in a smaller enclosure. meanwhile a medium strength magnet with softer suspension and smaller coil will need less power to get loud but requires a larger enclosure.
@@Techscrews Hm, I can tell for sure that some of the caps have started leaking fluid. But they could be working still, yes. I got a tip for you that I'm using on my R-115SW; buy a smart power-outlet that cuts the power to the sub at night, and when you're not using it. This will spare the amp a lot!
@@white_goose9782 Yeah, I got to read the first one, but it was gone a few minutes later. There wasn't anything wrong with your answer either 🤷♂️ You just tried to prove your point, which you managed to do. I read the article, and it says that the auto on/off function (on most models) does not save these amps.
@@Techscrews, oh, then it makes sense. ✌️ It's a nice looking sub though. But it's Klipsch, so of course it looks good. 😜 What are your thoughts on it? 🤔
the absolute worst to work on. try scraping glue out from between the spider and basket. it took me two hours to properly remove and re-glue a spider on this same basket.
I would have loved to see a real design analysis, like finding the port tuning frequency via impedance measurement. What size is the port? Frequency response and so on
you don't connect the speakers to the subwoofer, but speakers and subwoofer connect to sound source with 3.5mm splitter(in simplest way) or through DSP unit.
@@swllz thank you. I thought about that, but in the mean time I bought a rockin' SVS sub. Don't think my wife would tolerate me bringing the old one back to life as well. haha
@@Techscrews I think the subwoofer could benefit from a sealed enclosure or a passive radiator. If that's not the case, the port tuning should be a little different and maybe the enclosure size. But it definitely has to be reinforced more and maybe thicker wood to minimize resonances and even out the frequency response.
@@speakerpat 1/4 wave transmission line tuned at the subs FS. Sealed, ported, passive radiators are all garbage in comparison to a proper T-Line for flat response, loudness and accuracy.
That basket looks like it needs some dampening. Does it ring when you hit it? I got 4 of these, they are very boomy stock. If you use minidsp to time align and eq, they are very good. Looks like if I dynomat the basket and add some more bracing it would be even better. But I'm using them for cinema, so I'll probably let them be.
Wow wonder how much that unimpressive speaker cost. Knowing Klipsch 10'000 or something ridiculous. I'll stick with my Peavey black widows thank you. I like to rock out not connoisseur a song at 50 watts for 50 grand worth of tubes and overpriced equipment to hear an oboe.

For $450, you can't expect much. But it's totally in line with the Klipsch sound, boom boom, very powerful.

Thanks for the hint Sir, this was my Problem ;)
I loved seeing this Klipsch subwoofer from the inside, it has excellent construction.
Not really.
Look at sunfire subwoofer true mk2 it has a big magnet on the motor for being so small
@@leosvids1297 Yea! The 8" Sunfire júnior subwoofer really has a huge magnet.

Shitty construction.
Só falta agora trazer a desmontagem do SVS Ultra ❤
Dynamat on basket and internal enclosure will improve performance a lit bit, cleaner bass.
I’m surprised you had the guts to take a klipch sub apart 😂🎉
4:32 interesting chassis, with good ventilation
good to see inside

simple question are klipsch subwoofer speaker 4 ohms are 8 ohms
does this foam _do_ anything?
Which foam ?
@@Techscrews the white foam you pulled out of the inside of the enclosure?
3:18 Looks like the resistor has already cooked a few capacitors on this amp. Common issue with these subs...
It works like new as, hope long time and you just kidding me 😀 its just glue, not cooked 🤫

@@cyberarti thanks 💯
3:50 😬
**cking glue 👎
@@Techscrews, oh, then it makes sense. ✌️
It's a nice looking sub though.
But it's Klipsch, so of course it looks good. 😜
What are your thoughts on it? 🤔
Isn't it ironic that good old stone age paper is still considered the best material for cones?
You mean "fiber composite" dont you. 🙂
is it filled with wool? or what would you say is that in the inside
it's polyester wadding (Sintepon)
How i can find manual service klipsch r 120sw ..because my sub spoilt and number part missing..
so its an irs2092 based amp? not bad klipsch a cheap and good alternative for the amp
Can you change the sub to a different brand?
Of course, but it also sound different.
wery good pov . bu i cant see egsaust bas out hole
Thanks for posting this. What was the other electrical connection from the amp into the cabinet? I never saw it in the video …
It's for the front LED.

I dont have a such knowledge
1 thing I can't that is how to get the Output channels connection rom this SUB ????
what please ?

I mean output speakers ??
you don't connect the speakers to the subwoofer, but speakers and subwoofer connect to sound source with 3.5mm splitter(in simplest way) or through DSP unit.

My R-112SW amp failed after about 6 years of use. Wish I could find a cheap replacement amp.
Just go to repair shop and repair it.
I also got a failed amp in my PSB sub, I bought an used external sub amp to drive it, it works very nice.
@@swllz thank you. I thought about that, but in the mean time I bought a rockin' SVS sub. Don't think my wife would tolerate me bringing the old one back to life as well. haha
@@AztecHusBone , my PSB is more musical and detailed than SVS, so I would like to listen to it
my eyes were on the yamahas in the background :)
Please schematic plan box
i dont have that.
Eh, the amplifier and driver actually look to be pretty good. I think with a better enclosure, the sub would sound much better!
this is definitely not bad news, what you think should be improved enclosure?
@@Techscrews I think the subwoofer could benefit from a sealed enclosure or a passive radiator. If that's not the case, the port tuning should be a little different and maybe the enclosure size.

Thats a majority of where the cost cutting is. Yikes. Now i know to swap out the sub asap
why did you knel the sub so hard
