I am curious - how well mortared is the rock exterior of your building? And, are you planning to secure all ducting and conduit, and going the double-drywall + green glue and wall/ceiling treatments route?
As to lowpass and high pass, the low pass should be taken care of by your AVR - it'll recommend (or default to) 80hz but that's user-adjustable. That frees up your amps to highpass at 21hz or whatever the recommended setting is for the F-20s.
The vibrations were in my house...and was caused by drawers in the kitchen and pictures on the wall lol. The dinner theater at the winery will be setup specificially for this application and should not have the same issues.
The ceiling of the rooms in which the dinner theater is located will have drop ceilings (@ a hight of 18'), and I do not plan to double drywall, as the 6" exterior studs will be filled with 6" of open cell spray foam insullation. There is no duct work on this level, as it all runs beneath the floor, and is all newly installed as well. The exterior was just stoned last week with 2" thick manufactered stone (see below).
@ lilmike .... it was not my intention to hijack your thread with our specific application of your F20 design. One goes where the responses are
@ everyone ... if my build thread is the more appropriate spot for this dialogue, it may be found here
