The voice coil can be properly checked with a voltmeter. Disconnect the speaker and use the OHM setting on the meter to check to see if it measures around 4 ohms. Is this speaker a subwoofer? Some subwoofers will be rated at 2 ohms. Either way, any speaker should have a sticker or stamp on it telling what the impedence is. Typically, most speakers will be either a 2ohm or 4ohm measurement. If the coil is bad, you will either get no reading or one that is much higher than the 2ohm or 4ohm. Hope this information is helpful.

WHEN YOU PUSH DOWN EVENLY ON THE SPEAKER ITSELF...IT JUST SUDDENLY GIVES-WAY, WITH A KIND OF POP. DOES THIS MEAN THAT THE WOOFER IS BLOWN??? AND IF SO IS IT POSSIBLE TO REPAIR THIS TYPE OF PROBLEM? ...


The first thing to do is to check the resistance of the voice coil. Get an ohm meter & place one lead on each of the speaker terminals. If a value of 0 ohms results, or no reading at all, the voice coil is blown.

If you are pressing in, and suddenly gives way, my guess would be that the excursion of the speaker was too grand (common with car stereo, everyone loves bass) and the wires that wrap around the voice coil of the speaker were broken from the speaker inputs.

It is possible to recone the speaker, but by the time you track down a recone kit (highly unlikely that it is even available) you would be rather deep into the project.

Long story short:
check the speaker terminals with an ohm meter. If you get a resistance, they should work with free woofer movement. No resistance = blown woofer.

They seem to stick and not move when i play music


Voice coils are burnt. Usually caused by under powering and over excursion of the driver. They only move so far then jump the track so to speak. Pull the driver and put a meter on it for resistance. if it's cooked, it will say 1.....
Any car audio shop can do this for you as well, usually for free. Hope this helps

Volfenhag ZX4725 i am buying this subwoofer and


No the LOWER the resistance the MORE Output or Draw, If say it is 100 Watts into 4 Ohms, if you used a 2 ohm speaker it would draw 200 watts.(only if capable of delivering that amount of power) The LOWER the Resistance, the HIGHER the Current Draw. WATTS = AMPS x VOLTS. (This is not strictly true with amplifiers output though, as it is an AC Current, and a "Reactive" load, it has, Inductance, Capacitance and Resistance, all in one.and is worked out via a Formula) see below. http://en.wikipedia.org/wiki/Audio_power

Now with Dual Voice Coils, Essentially, you can think of these speakers as TWO speakers in ONE enclosure. As such, They are basically TWO Speakers. Please see the website below it explains everything for you. http://www.diyaudioandvideo.com/FAQ/Wiring/
Everything is a function of Resistance and Ohms law.
Current (I) = Voltage (E) divided by Resistance(R).
Voltage = Current Multiplied by Resistance.
Resistance = Voltage divides by Current.

I BLEW MY AUDIOBAHN AW1208T SUBWOOFER AND WANT TO KNOW IF IT CAN GET FIXED I THE THINK ITS JUST DUAL VOICE NOT SURE THOUGH


is the rubber surround blown out.. look at voice coil itself .. it could be repaired but maybe not worth it. can u actuate the speaker down and up.. if you can then the voice coil is fused.. and if u can and u hear or feel resistance then there is work to be done to the voice coil and spider. Could be costly.. if its just the rubber.. use silicone to re-seal it.. ol skool trick..

One is broken


Does it smell funny?Smell around the top of the magnet and see if it smells like burnt plastic.If it does then the voice coils are burnt.Push down in the center of the sub if it dont move at all or has a grind the the voice coils are burnt up.Look at the lead going from the wire hook ups to the speaker cone are the intact?If not thats your problem.

How to repair a blown sub


i have a problem, i dont think my speaker is blown, but , it just looks like the wiring broke on the coil at the end that connects to the cone, i think thats how i can best describe it..its a 10" pioneer IMPP w/ integrated voice coil cooling system 500w max and also it looks like where the wires broke, the coil cam unglued from the cone.. hope someone can help me..is this something i can repair on my own or is it garbage?

Blown voice coil (punch)


No. You would have to find a vendor of the wire used in voice coils and wind them yourself, which also means you have to pull the cone out without damaging the surround or spider , and be able to put is all back together too . Your best bet with an older sub is to find a good deal on ebay.

Wiring woofers


Well, you have the 4 ohm dvc kickers, and your amp being stable to 2 ohms doesn't go together very well. If you wire the voice coils in series, and hook the speakers to the amp in parallel, you get 4 ohms, which doesn't use all the power your amp is capable of. If you run the voice coils and the speakers in parallel, you'll drop the resistance to 1 ohm, and probably fry the amp, or at least deal with overheating issues. Better be safe than sorry. You need to run each speaker in series, which means running a positive and negative to each speaker, and a jumper from those terminals to the opposite colored terminals on the second voice coil. Diagram can be seen here: http://www.kicker.com/06/tech-support/manuals/manuals/02SoloBaricL7manual.pdf That puts two 4ohm voice coils in series, and raises the resistance of each speaker to 8 ohms. Then, you have to run both speakers in parallel to the amp. When you run two 8 ohm circuits in parallel, the total resistance of the circuit is 4 ohms. That means seperate positive and negative wires to each speaker. If it is a mono amp, connect both negatives to the negative output, both positives to the positive output. If it is a multi-channel bridgeable amp, You'll probably connect the negatives to one side output (right for example) then connect the positives to the opposite side output (left for example). If you need to bridge your amp, make sure it is bridgeable, and also that you have the speakers bridged to the proper amp outputs. If not sure, reply back here with the amp model number, and maybe I can help you further.Thanks, and I hope this solves your problem.
