A couple years ago, I purchased several subs and two amps. I started building some large enclosure ported subs but my significant other did not approve.

So, now I am hoping to build something smaller.

Subs: 6 x NHT NPT-11-075-2

Amps: 2 x MCM 50-6262

I have included specs for both of these as attachments. In playing around with box designs in WinISD and with suggestions from other users I have decided to try my hand at an isobaric system. Space is a real problem for me.

WinISD says that if I put three pairs of my subs in an isobaric EBS3 configuration I would need an 8.8 cf box.

In theory this would be tuned to 16.5hz with 118db @ 20hz.

Problem is, I have no idea how to design this box. Any help is appreciated.
