[QUOTE="Buck, post: 8859065, member: 591582"] Ok. You have 4 18’s on let’s say 20k to make it easy. Your cabin is relatively tiny. That box being in your cabin is like 4 18’s playing inside of a large sealed box or look at your box in reverse like your cabin is your sub chambers. My point is that your cabin isn’t that big and should be well pressurized by the absolute monstrosity of a system you have; that’s a ton of wave energy density per volume of air. You are losing pressure in the cabin fairly early for being tuned at 27 hz, which you really should check to make sure the tuning is that from the structure of the box. For it to fall off that quickly and not be tuning, you’ve got too big of a box, port issues, 1/4 wave cancellation issues (or some other phasing issue), something of that nature, if I’m understanding you correctly. There’s a mathematical reason why it would fall off that hard, so I would figure the why before you figure the solution. [/QUOTE]
