The Ultimate Subwoofer (BD-Design)

However "blasts" or "sucks" will likely not reach the mbar range but still keep it self to low pressure db's. And I don't think anybodys listening room is that airtight that such attempts to alternate from over pressure to vacuum would be a real problem here.

The SWING is "protected" by partly the connected amp and partly by it's enclosure.
If I disconnect the BD30's from the BD15's I can move the diaphragmes somehow easily, but with the amp connected, they become extremely stiff. So the control is still in the hands of the amp rather than a woofer wall alternating deep low.

The wall will neither act like a Mike Tyson fist but simply just move air in the low subs when called for.
If the SWING and the wall works like a parallel piston (in phase at any frequency) the room will have to deal with the pressure alone. And that's another case.

But let's see what the rumble project at Brinkersweeg can show us. :wacko:
