2 amps on 1 Dvc subwoofer?
 
Hello people

Ive recently opened a thread up called "2 amps better than 1?" where I wanted to power a dual 12" subwoofer with 2 amps but the ohms on the woofers were not in a very nice way for me to get the highest power uot of them

Is it possible to use 2 of the same amplifier on a dvc subwoofer? (an amp on each coil)

Im asking this because, both my woofers are is the same box without a divider and If remove one of the woofers and covered the hole it left, the single remaining woofer gets its recommended litres and goes a lot lower,

cause then I could sell the other subwoofer :)

What are the bad points of this?

If I remember correctly it was DanWiggins who adviced AGAINST using 2 amps on a single DVC driver... the result may be total meltdown

Hey thanks,

I want to know A little more though,

What if both amps have the same source and are both set to the same settings? I know there are slight component tolerance differences but how will it go?

or is this a bad idea cause I cant see why it will be

Something to do with the amps seeing each other through the voicecoil inductions, dont know exactly how or why, but it is so

I never heard this before and have been doing this in my HT for about 5 months now....hmmm
I have been testing a single
15" DVC (4 ohm vc each ) sealed sono tube sub with one stereo ESS amp currently and have tried my 2 DIY monoblock Krell 150's with no issues on this same sub

never a hiccup so far

So it works well and you cant tell anythings wrong, does it just work like a normal except that theres 2 and theres a lot more power and control

Wouldn't be the same as two channels. One on each VC?

I thought that was the main purpose of DVC.

Wrong?

Yeah thats what I thought, but im going one step further, both amps will be getting the same signal so there no difference between left and right

surely using 2 amps on 1 DVC sub is the same as using 1 stereo amp on the sub??

Exactly!
