Wow you (audiophiles) have never taken the time to listen to a good car stereo! Take a look at the new DSP’s for car audio it’s come a long way. Educate yourselves first. Some people spend 200k on 2 towers some spend 200k designing door pillars with multiple drives. Then there’s the people that say we’re all idiots.
OP
id recommend multiple subs for equal response through the room but place a few directly behind the couch or anchored to the couch but decoupled from the floor to avoid extra resonances. 4 10” is all it takes. Tune them very low and you’ll get the pressure in your chest with out getting to loud. Use a minidsp hd to switch sound curves from rock concert to classical. I’d stay away from tactile transducers because they offer no SQ.
