This video is the answer to making a subwoofer!. Best!
Ayos ah,. Ok to sa mga amp na walang built in na cross over
Tama yan tlga use nyan para sa mga amplifier na walang xover.
Buen aporte amigo
Using only the wire coil in series of the Positive makes a 6db per octave crossover. Good enough for my tastes, and no capacitors to worry about
Using only the wire coil, about where would the cut off start?
@@romantea3506 using just the coil is fine. Look up "crossover calculator" and "1st order pass" mode. And it should tell you what coil to use
Now you are talking, i've been going to and fro looking for this filter, but now i've found it
Watching sir👋
It better with stranded iron wire core or ferrite instead bolt + nut. Low size iron particles are less generating eddy current, thus lower heat..
What is the uH value of the inductor?
Ganda pang soft bass
Boss ok lang ba tumaas ung voltage ng caps like 250v?at boss kung mababa namn ang value ng caps like 470uf anong effect?salamat sa sagot boss
Sir idol itatanung kulang Kung pwede ba #18 na magnetic wire
Pwede nmn lods. Basta habang tumataba ang wire eh mas lalong bumaba rin ang low pass filter.
Hey bro
I've a technicall question. Can I use LPF filter at input of amplifier and connect directly The output of amplifier to The subwoofer?
Yes, I currently have a set up that kind of works that way. Just make sure your amp has its crossover, disabled, or set to full. In my set up the deck has a built-in crossovers and only output specific frequencies to the amps. Slightly more efficient on the amps.
@@iNFiNiTY125hey can I do this with the logitech z5500 sub
The bass is same just with this filer cut mid high
Sobrra filter
nice tutorial 👍,, sir ask ko lng sa gnyang set up ngbabago ba ang impedance ng speaker? kung 8 ohms ang speaker tpos nilagyan ng gnyan 8 ohms parin ba?
Posible magbago ng konte
Sir kung babawasan yung ikot ng coil medjo tataas ba yung range na marrecieve ng driver? Parang around 300hz? Tpos same capacitor ba pwede padin gamitin pag ganun ginawa?
Di ko gaano gets tanong mo lods. Pero sa paggawa ng passive crossover me tamang calculation na nakadepende sa mga ilalagay. So magbebase ka sa frequency response ng driver at impedance driver.
@@TAWITIBoyAllAround salamat po sa response. sorry samalabong tanong hehehe
ibig sbihin ko lng po is yung binanggit niyo po kung ilang ikot ang gagawin, what if hindi ko gawing 400+. how bout around 200 na ikot lng? balak ko pa kasi hindi masyado low pass filter. yung parang mabawasan lng yung high frequencies na binubuga nung speaker ko. 2.1 setup po kasi yung project ko. hehehe dami ko tanong
What does the capacitor do here what happened if we don't use it?
Low pass filter
sir ask lng,, pede ba yan sa speaker na tag 25-30 watts? my mga babaguhin ba if ever na pede?
Pwede
Sa pang 5watts na speaker Anu po maganda Gawin para gawing lowpass filter .
Either active low pass filter or passive low pass filter rin. Pero sa 5watts na speaker is not recommended pa na maglagay ng low pass filter kasi masyado na mahina yan. Dpt at least 50watts man lang.
Ok sir salamat try lang sana hehe
gud non sir.meron aq sub mobiletec 12 400w. ok lang ba sa ganyan lang din na pasive x over. sana masagot nyo sir.tnx
Opo
El capacitor es polar o no polar.???
Non polar
Kapag dual vc yung speaker sir, tapos ginawang 2ohms, kapag nilagyan ba ng filter 2 ohms pa rin ba reading nun?
Kpg naglagay ng inductor posible tumaas ang impedance.
@@TAWITIBoyAllAround salamat sir
Sir ilang mm bayang bolt nyupo? Sinubokan kopo kc yan parang iba sakin ginawa pro gumana nmn ang filter ng vocal.pro d kasi bayu. Kc sa tindahan mm kc hinahanap sakin hehhehe
1/4 size di wari kung 12mm ba un or 14mm.
lods pwedi ko ba lagyan nyan ang 8" hybrid sub 250W nyan?
Yes
Yang sub mo po, kaya po kaya ipower ng tpa3116d2 2.1 amplifier na 24v ang power source? Maganda po kaya ang tunog ng sub na yan? Ok po kaya siya sa L ported box? Gusto ko po kasi yung soft at deep bass. Sana po masagot niyo po. Bubuo po kasi ako ng 2.1 system
Bitin tpa3116d2 mo kpg yan subwoofer na yan ang gagamitin. Ok sya sa Lported basta tama lang ang pagkakagawa.
Pwede niyo po matignan itong mga sub kung saan sa kanila ang compatible at kayang idrive ni tpa3116d2.
6.5 inch subwoofer

8 inch tosunra subwoofer
shopee.ph/product/104512880/8024543128?smtt=0.121541179-1633560613.9
Yung tosunra sub po may nakita akong nagreview non tapos sound test pero walang mga box. Gamit po niya is yung tpa3116d2 2.1 amplifier pero baka po kasi di kayanin ni tpa yung sub kasi sabi naman po 800W daw pero di ko po kasi alam kung ano RMS power niya.
@@TAWITIBoyAllAround yan po mga choices kong sub kasi nakita ko po yang sub mo sa shopee nasa 800+ po pero budget po kasi ang buo ko.
May ganyan ako sir bakit pag tinotodo mo parang may plastic na tumutunog
Baka di compatible ang passive xover mo sa mga speakers mo.
Lods pwede ko din po ba lagyan yung speaker ko galing sa speaker ng component? Ginawa ko kz ng bagong box sya at sa amp na platinum na 302 ko sa ikakabit e,
Pwede
@@TAWITIBoyAllAroundpwede po ba kahit wqlq na capacitor?
How many meters of cooper do you need for that?? Because it's easier that way😅
Go to the12voltcaraudio website, you can use the calculator there as reference
kung 15" 800w peak na speaker.. same lang po ba gagawin?
800w peak so mor or less 200w true rated rin yan kya pasok pa yan ginawa ko passive low pass filter.
@@TAWITIBoyAllAround ayun.. thanks po sir.. =)
pwede po ba yung 25volts 2500uf
Mababa masyado
kahit ba lods walang capacitor? kase humihinto hinto ung tunog kapag naka parallel ung capacitor feeling ko nag shoshort circuit ung capacitor bipolar pala ung caps na gamit ko 2700uf 25v
Hindi filtered ang bass kpg wala caps
@@TAWITIBoyAllAround pag masyadong malakas humihinto hinto sya minsan nag rereboot ung ampli
Sir pwede po ba wala ng coil? Meron kasi ako dito 470uf 16v kabit ko sana sa + at - , pwede po ba?
Kailangan tlga ng coil inductor. Tatalon talon tunog ng sub mo kpg filter capacitor lang ang nailagay mo. Tsaka mababa volt ng cap mo.
Prang dividing network xa bos
Passive crossover ang right term. Yes, un yan mismo kaso single lang yan kya passive low pass filter lng.
2nd order yan n filter. Important yan for tuning crossover point ng spkr. May idea c tiwiti medyo kulang lng sa hulog .
May Qfactor at topology ang lahat ng filter. C+Lmay tamang computation yan for frequency point address.
Keep support p rin kay tawiti.
Tanong lng po. The more winding poba the more mataas wtts ang kayang epifilter?
Meron tamang computation para jan. The more na dumarami winding mas tumataas ang resistance at napifilter na high frequencies.
@@TAWITIBoyAllAround thanks for sharing.. I think need ko pag aralan calculation ng tamang winding depende sa subwoofer.
Ano Guage ng wire boss? Pwede #19?
Depende sa gagawan or lalagyan un may computation po yan
lods...may tanong lang ako...dual impedance yung sub ko..8Ω, 8Ω sineries connection ko.same procedure lang ba paglagay ng low pass filter kahit nakaseries?
Same lang kaso sobrang taas na ang impedancr nyan kung dvc 8ohms na sineries mo. Hina na output ng amplifier.
@@TAWITIBoyAllAround salamat sa sagot lodz
Good pm sir ano po ag tamang rating ng capacitor uf. Na nya po pra sa 100 to 60 watts speaker n 6.5 inc. Po
Depende kasi sa balak mo habol na tunog un eh at proper computation rin. Pero kalimitan inilalagay is 1000uf na khit 50V.
Salamat po sir sa idea
How many meters of copper wire needed
Pm me
hi po boss shoutout lodi. may itatanong po sana ako. pwede bang gamitin ang capacitor lang pang increase ng bass. at paano po ito gawin.salamat po sa pagsagot
Filter ang capacitor at kailangsn rin n inductor coil n kmatch.
lods parequest nman.pwede po bang gumawa kayo ng vid. na related sa bass booster.salamat po
Para saan po yan sir?
Para walang high frequenvy ang pumasok sa subwoofer pra mas maging efficient ang tunog ng low bass.
Normal lang po ba na umiinit yung coil sir?
Oo nmn
Masyado namang nawala na yung base,..
Wala kasi sa box kaya parang totaly nawala. Pero tingnan mo nlng movement ng cone halos same sa movement ng wala pa ung low pass filter. Although humina ng konte ang lakas kc nagdagdag ng resistance dhil sa inductor. Ng iseries. Sa amplifier nlng bawi ng timpla ng built it preamp kung walang active crossover.
Hi Tawiti, you've used too much capacitance, use anywhere from 200uf and then increase accordingly..
200uf only allows frequencies from 200hz and bellow great for bass! 😃👍
