Dual coil VS Single Coil Subs

[zorrt]

Hey guys,

Does a dual voice coil sub really make much difference as opposed to a single coil one? Like what would be the noticeable difference?

I was thinking of getting this jaycar one

but not sure if 10" is big enough and i cant afford the branded subs.

No difference, it just changes the wiring configurations.

Yups
If its a voice coil then I think all you get is a bit more coming out of the sub besides the "bass" e.g. some unclear music? its called a voice coil right? correct me if im wrong

I was reading on DVC and the description says the advantage of having dual coil is that you can run 2 channels through to the amp instead of the one. But I'm still unsure of what this does in regards to sound quality.

dual VC gives more flexability when connecting sub(s) to amp(s). Nothing to do with sq output.

A single coil sub and dual coil sub don't have a lot of differences, but a dual coil sub can have wiring done a certain way. Basically, dual coil subs offer more flexibility in wiring. A single coil sub is just connective -ve to -ve and +ve to +ve. In a dual coil sub, you can have either series, parallel or independent wiring

PARALLEL - You just take the wiring from the amp and split it so the 2 wires from the negative terminal in the amp goes to the 2 negative in the coil and the 2 wires from the positive into the 2 positive terminals in the coil.

SERIES - The +ve terminal of amp to one positive of one coil, that same coils negative terminal to the other coils positive terminal, that coils negative terminal to the -ve terminal of the amp

INDEPENDANT - This is when you take 2 channels, you dont bridge them, but u run +/- from one channel directly to one voice coil and +/- from the other channel to the other voice coil.

It is beneficial because you can change the impedance levels. Like, a dual 4 ohm voice coil wired in series has something like 2 ohms and parallel has 8 ohms. Its more beneficial if you want to run multiple subs off one amp.

oh ok then! thanks! lucky i bought a single coil one only, cheaper =)

u need a monoblock amp for the DVC sub to be at its full potential anyway, otherwise it wont make a difreence, and yes if u do it right it makes a diffreence i've heard DVC sub on a monoblock amp it sound like u have 2 subs installed

dvc will double the power handling. hence +3b gain. in other words, a dvc (with more power) will sound as loud as 2 svc.

What is the difference between single and dual voice coil subs?
It is easy to confuse a dual voice coil sub as a better subwoofer, but that is not the case. You will get the same output from either sub when used in the right application.

Of course a sub with more power will go louder, but i'd like to know what you're basing your assertions on.

the point is a dvc sub can handle double the power. if u put that amount of power in a svc sub, u might damage it by overpowering it.

Oh god you have no clue do you guys? DVC is purely for WIRING purposes only.
