Hi Oz,

Yep, you can't get around the laws of physics. No magic is involved. If you keep the driver diameter constant and increase the internal cabinet volume, then you get deeper bass extension. In a ported (bass-reflex) system, you can "tune" the system and adjust the port size for greater extension. I'm simplifying here because there are many different trade-offs in getting deep bass extension. However, that's a given: You have to increase the enclosure volume to get deeper bass.

I noticed you have two-storey ceilings. I'd absolutely recommend you get the M80ti's. The greater internal volume of your room should simplify placement somewhat. The drapes (open or closed) would increase or decrease, respectively, the "liveness" (reflection or absorption) of the room.
