I was wondering if it was ok to put all 4 subs in one sealed enclosure without any diving mdf pieces. Im kinda low on air space so I need as much air space as i can get. Thankyou

its always better to seperate the chambers but it wont hurt anything unless a sub blows. if a sub blows then it will sound sh!tty and you wont be able to take the bad sub out without a direct replacement. i would atleast make 2 chambers. it will help stiffen the box and if one sub takes a dump then you can still run 2. a 3/4 inch mdf wall inside doesnt take up all that much airspace.

Are you using two different amps?

As ss-installer pointed out, bracing will be a critical factor with a box that size. This may be a case where 4 subs is a few too many.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I second the question on how many amps are you using. If you are using one amp to power all 4 subs than its probally not gonna be a huge deal unless you blow a woofer, then you get into the issues that ss-installer pointed out.

ya he is using one jbl 1200.1 amp for the 4 subs. So if he could should try and sqeeze in seperate chambers for each sub and just use polyfill to make up for the loss of airspace?
