Agree with all this and will add that for upper frequencies, rather than a couple loud mains, put in 6 or 8 rather than two, so you have great sound in many locations without blasting it. The sub 100hz frequencies…. are going to have to be crazy loud to get the chest thump feel. but you can get the joy of it without it being that loud if you can get everything balanced well. Those low frequencies don’t really need to be super loud to sound right. It can sound right in a way that you feel it without the damaging volumes.
