Help connecting external subwoofer - Page 3

post #21 of 26
ummmmm...no. The other coil is NOT getting "power" if it did then it would react like a coil does and impart a field and move the speaker.

All a voice coil is is an electromagnet, it is around a pole (magnet), as the signal is sent to the VC, it builds up a field and reacts to what the signal tells it to do.

If there is no signal to a voice coil it will not react.

The two voice coils are COMPLETELY separate from each other electrically, that is how a dual voice coil speaker can act as two speakers.

BTW...heat is bad for VCs that is why there is vented poles

I don't mean to argue here....but it will get power. Hook up just one coil on a dual voice coil sub...then hook the other coil to another speaker/sub. The other sub/speaker will get power...even though that second coil is unhooked. And while the two coils are wired seperately....they are still ran directly next to each other, which the magnet causes the other coil to get power even though its disconnected. Its done through magnetics.

A single voice coil sub is just a single piece of wire, and you're hooking up your + and - to opposite ends of that wire. A DVC (dual voice coil) has two wires coiled together...to make a total of 4 connections. They are ONLY meant to be used to get a wider variety of resistance (ex: dual 4 ohm coils make 2, or 8 ohms).

Ok, well I connected it like this. Works perfectly! With all the volume knobs centered the volume ballance is perfect too. It's like this was made to be done

Oh I dont take this arguing at all

what you are seeing on the second SEPARATE speaker is called "inductance" from the non-powered VC moving up and down a pole

now you are looking at the opposite edge of said sword.

move a coil of wire up and down a magnet and you will create voltage

All you are seeing is the inductance created by the "powered" VC moving the speaker...while the second VC creates inductance and you are utilizing the voltage created to move the separate speaker.

In NO WAY, would this action hurt either VC

EDIT...nice job fishie!! sorry we went a little OT to lament on how a speaker works

ROFl, you guys

It's ok, I never disconnected either coils anyway. I don't know how you two started talking about that

the structure of a speaker and how it works has been an argument for millennium....ever since the first caveman yelled in a cave and it echoed throughout the lands
