...driven by the main stereo signals on the back wall, left and right of the couch. These operate as 'true' SWs with a low-pass-filter point of 25Hz. (The LP filter is 2nd order to around 80Hz and then becomes 4th order. Another way to write that is that there's an 80Hz LP filter that's nondefeatable.)
These really do stretch the system's bass extension in the bottom octave and below, and they sound to me (and others who are GEAs) to integrate very well with the Super-Sevens.
After fooling around with various analog multiband EQs to reduce, mostly, the strong 28-30Hz room node, with varying success (mostly poorly), I've minimized the bass resonances in my room with a pair of RANE-brand commercial 3-band parametric EQs.
Each band is continuously adjustable from 10Hz to 20KHZ. These work very well. :-)More pics at the link.
I also have a pair of the previously mentioned double-12"-servo open-baffle woofers as part of my Serenity Super-Seven speakers. These use a special version of the Rythmik 370-Watt amps previously mentioned.
The highly over-rated Coincident Frankenstein II poweramps in this pic are long gone.And altho I mass-load most equipment in my system--see, for instance, the Coincident poweramp in the pic immediately above--I've not considered mass-loading these SWs as someone else mentioned; I too have lots of 25-pound bags of lead shot.
