Subwoofer

Hey, I've got the ginormus sub woofer thats crazily loud. But the computer doesn't make much use of it, it will only work if the bass is super deep. When i plug it into my ipod it works normally. Any help to make it work better for my computer because it was originally made for my computer?

Limit of a subwoofer

Guys the question sounds like stupid but the thing is how should i know a subwoofer reached it's max excursion limit before blowing the coil.If it starts to distort does it means it reached it's limit or the amplifier can't provide much juice the speaker needs.

sync bass with subwoofer

Hello, I thing this is the right /r/ to ask this. I have a HTiB and I want to make 2 led strips with ~6 meters blink with bass. I have done some tests with my old subwoofer (logitech z5500) and I noticed that as the bass goes deeper, I got distorsions... I have read that we can use an amp to store energy (? :S) but it could start a fire due the heat. Can someone help me? Obviously I can use the leds directly conected to the subwoofer and dont turn the subwoofer volume to high and everything will be ok, but I really want to make something cool and safe. The HTiB this an Onkyo HT-S9700THX, and the subwoofer is powered directly to current, the amp just pass signals. I thing this is called a pre-amp subwoofer, correct if Im wrong please. Regards and thanks!

Can I add a subwoofer to a stereo system that has no subwoofer?

I have a stereo system that has a left and right speaker that connects to the main part of the stereo (CD player and the radio). I was wondering if I could disconnect the speakers, from the CD player itself, and make a circuit that amplifies a low sound bass, then connected to a small subwoofer.  (Instead of a normal amplifier that just makes treble sound louder.) Then reconnect the two speakers so the final result is that there is an amplified subwoofer.

Subwoofer lost its "WOOF"!!!

So i purchased a pair of 800w 10" subs at a yard sale for 20$.  They were cheap so i assumed they were faulty but figured i could try fixing them. So i get them home, hook them up to an amp and nothing happens... until i place a little pressure on the cone and  thump thump thump, they work... and they're heavier and hit better than a pair of 1200w 10" Sony Xplodes i have... until i let go of the cone.  I'm reading things about blown voice coils and what/not and was hoping someone had an idea how to replace one. Or if my problem sounds like something else all together.  Any ideas DIY'ers???

wiring my subwoofers to amplifier?

4 Ω x 2ok i have a  JBL amplifier    and a pair of pioneer dual coil subwoofer with impedence 4 Ω x 2  ( http://www.pioneerelectronics.com/PUSA/Car/Subwoofers/Champion+Series+PRO/TS-W3002D2|D4 ) i'm not sure if it will work just fine if i connect the 2 subs to the amp at 2ohms each, because i wired it to make a 8ohm impedence on each sub and works just fini!!! but  i'm not satisfied with the output power will it work fine if i connect both subs at 2ohms impedance(set the coils in parallel on each sub) on each sub to the amplifier???? don't worry about the power delivery, i have a 2X10farad capacitors, and a 55AH battery installed in the car

Diagnose 2.1 Speaker Subwoofer Problem?

I picked up this 2.1 Edifier M3300 Speaker set at the Goodwill cheap. The Right RCA connection doesn't produce any sound except for a buzz. The left connection is fine. I check the speakers and they both work when plugged into the Left connection.  How do I figure out how what is wrong? Could the amp be broken or just the connector? I don't mind just 1 channel, but if I could fix it, I would like to try. If it's too complicated, I'll just leave it alone.

I'm stuck between a rock and a voice coil.

I know I think I've posted a question like this before. I have a new sub, it's a car subwoofer origionaly (200 watt max (not rms)). So far it's running off the internal amplifier that came out of my old/blow sub (it was rated for around 100 watts). And I have it ported out the side. I had to do some work on the dust cap, it was torn and the torn peice was flapping and making a lot of noise, so I put nail polish enamel on it, a few coats and seems to have worked, but now on the odd beat it sounds like one of the wires going to the voice coil are loose or it's rubbing on something because it makes almost a crackle noise. I figure if it was rubbing, it would make that noise on every singe beat, but it doesn't always. Is there a chance some of the enamel dripped down into the thing the voice coil sits in and it's rubbing somehow? Thanks for any ideas guys!

How to set up a powered subwoofer pc speaker set, without the powered subwoofer?

I have a set of pc speakers, no mfgr markings, that were to include a subwoofer. Given to me without the subwoofer. Only reason I know about subwoofer is one side has a port that has printed next to it,"to subwoofer." I'd like to just make it into a set without the subwoofer. It has 3 stereo male plugs, in weird configurations, and I think it may need rewiring. Also has a volume "wheel" switch on one speaker. Oi, this is too much trouble, isn't it? Well, anyone have ideas, even if your suggestion is to go buy a new/cheap set. Thanks folks!?

I need help with subwoofer box designs!!!

I've got this new alpine (well not new, but it still works) 12 inch subwoofer. The box it's in was probably alright for in the trunk of the car, but I'm planning on using it inside, as my sub just blew. Here's the size demensions of it: 15" wide, 16" high, and 13" deep. There's a hole about 3" x 2 1/4" in the back for the wire to come out. I was planning on using the internal amplifier from the blown subwoofer, in this box, but I need to cut a hole to fit the amplifier in. It sounds really punchy, but for a 200 watt subwoofer (that's rms) it doesn't shake my floor at all because it's basically a sealed box, the sub comes out the front, should I cut a hole in the front or side for a port? What if I used the pipe out of the blow subwoofer box, or is it specifically tuned for the 8" that was in there before? Thanks for any help.

Home used subwoofer can connect to car?

I have a home used subwoofer with 220V AC. It has a transformer input of 220V AC, and Output of 12V 2A. I want to fix that subwoofer unit into my boot of the car. My car is running on 12V NS 60 Car battery. To run the unit with car battery I may have to bypass the transformer of the unit and give power from the battery directly to the Amplifier. I have two questions. 1. Is it safe to get a direct power line from the car battery to the unit. 2. How to identify the place in the circuit board to connect the power line from the car battery. (Sample diagrams are very much appreciated)

Subwoofer output from my creative card??

Hey guys, can someone help me with this?? I have one of these sound cards, as you can see in the picture. It's worked pretty good for me for the past couple of years, but usually the subwoofer output comes either straight from the normal 2 channel stereo output on the card, piggybacked onto the cable that goes to my stereo and then that goes to my sub amp. Either that or right now I have the subwoofer amp hooked up to the line-level subwoofer output on my surround reciever, but it's still 2 channel audio. I've recently been fiddling around with my sound card, attempting to get the subwoofer output on it working. I've tried the black socket on the sound card with a 2 channel 3.5mm to RCA cord and apparently it's the rear channels as the subwoofer volume slider didn't do anything in my creative control panel, and according to a pdf I found online for my sound card, the S/PDIF socket also functions as the center/subwoofer outputs when not being used for S/PDIF. I've tried a 2 channel and also a "3 ring" 3.5mm cable I have for a camcorder (As I believe some of the cables that are SUPPOSED to go with this card, have 3 ring contacts on SOME of the cables). Alas, all I've been able to do is get a loud humming sound out of the connections, doesn't matter what rca channel the subwoofer is plugged into, it hums VERY loudly and absolutely no sound what-so-ever. Does ANYONE have any clue as to what I do to get subwoofer output from the card?!? Heres a link to the PDF describing what each port is for under "Creative Sound Blaster Live! Digital Entertainment 5.1 Creative Audio Software" and then the submenu "Installing sound blaster Live@ Player 5.1" and the next submenu "Connecting Related Peripherals" and that page describes what each port is for. files2.europe.creative.com/manualdn/Manuals/TSD/790/English.pdf

What can I do with these???

Hello again, I want to bug you guys again, if you remember, I just fixed these JVC speakers as the seals were gone on the plexiglass. Now that's fixed, I've been noticing that when I play almost any song past volume 20-22 I can really notice a lot of turbulent noise from the tubes, and it's not the seals this time, they seem to be holding out. It just sounds punchy and the noise coming from the tubes kind of ruins the fact that I fixed the seals already, theres 4 screws around where the tube goes into the subwoofer chamber, but I tried taking it out, but it still wouldn't come off even though the 4 screws were removed. Does anyone have suggestions on how I could make these speakers sound better??

A/V Cord to Typical Stereo Wires? Answered

I have a surround sound speaker system that only takes the typical stereo wires (you know, positive and negative electrode inputs for left and right side). I also have a stereo reciever that only provides A/V outputs. I was pondering how I could make these work when I realized that, even with an A/V cord, it still needs to make a complete circuit. Thus the cord needs to have two wires going through it, and the plug had a way to complete that circuit. Now that I know this, I want to know if I can cut the plug off of one end, strip the wires apart, and plug those wire ends in my subwoofer? If anyone knows if this is possible, please let me know! And please help me determine which wires are positive and negative current. THANKS!

Low frequency amp? Answered

For a future project (blue barrel infra sub woofer with ducted fan) I'm already looking for parts. I see most amplifiers and amp chips (like the TDA7294) have a frequency response usually 20 - 20,000 Hz. But I'm interested in a range from 0- ca 40 Hz. As far as I understand, the low cutoff is to protect the driver (speaker). Would it be possible to circumvent the low cutoff, or would I have to build from scratch? (I'm thinking in a 70 - 150 W RMS range).
