Hey
can someone tell me all the pros and cons with twin voice coil?

thanks

more wiring options to better match the load to ur amp.

Theres my 1

Yeh, more wiring options other than that....there's pretty much no diff at all

Had this discussion with someone the other day actually, and this is what I sort of came up with. Please bear with me while I state some theory:

In a Dynamic Moving Coil Speaker the voice coil is situated in a circular gap in a powerful circular magnet. When an alternating current sent from the amplifier passes through the voice coil, a force is exerted on the voice coil by the magnetic field which in turn moves the coil and the attached speaker cone, in the direction of the axis of the speaker. The alternating current moves the coil and cone rapidly back and forth as the coil is attracted then repelled by the permanent magnet.

So, in theory (apart from the wiring options mentioned previously), having two voice coils may actually improve the accuracy of the speaker's movement.

Anyone know any other advantages?

well i know one advantage for me is that 2 v/c's makes its LOUD
ive got one amp at the moment on it but u can put 2 amps on it, i'll be putting 2 mono blocks 400rms one onto each v/c
:badgrin:

I'm not sure that's a good idea. Both voice coils are attached to the same cone, right? Well, what if the signal from each amp is slightly different? Surely you're just asking for trouble doing that?

nah caz they are digital amps will be easily set up so they are excatly the same

but yeh u are right if 2 different signals go in, by by voice coils

Ok so i will get better bass with a twin v/c than a single

so if i get a sub, twin v/c 4ohm 500w rms, does that mean each coil is 250w rms 8ohm??

Class D or "Digital" Amps doesn't mean they're easier to adjust, it's just a different method of amplification which incidentally is more efficient than Class A/B amps.

So, in theory (apart from the wiring options mentioned previously), having two voice coils may actually improve the accuracy of the speaker's movement.


Yeah, this is probably true, but u would probably never hear the differences.

I tend to disagree. How could dual possibly make it more accurate? Remember the single voice coil is usually twice the size of the dual voice coil of the same type of subwoofer.

If it did make it more accurate (tiny bit more surface area facing) it would be way above the hearing abilities of the human ear.

Yeah, I see where you're coming from, I was just speculating.
