Yeah we double up 3/4 sometimes as well.

 

If use Prefabs then we usually try and reinforce them a little. Seeing that a good amount of them are seperate chambers, you can run some screws in to the divider.

 

I'll throw my opinion in.....there's nothing wrong with a shared chamber. I've built hundreds of boxes that way, and i don't think it's ever been an issue once. Built right they're not going to flex, so that's no concern. Blowing one sub and eating up the other is potentially true, but when even some of the less intelligent people I've dealt with blow a sub they seem to notice it. Always utilize proper system design and people won't often blow subs anyhow.

 

we arent talking about bandpass and the subs are close together..

 

Oh, well then I guess we should stop talking about prefabs then.

I wasn't talking about the subs being close to each other. I was saying away from the listener.

 

they are directly behind the listener.. owell IDC.. if they sound good.. good for them.. if they blow or w/e they were cheap so who cares.
