I will just copy some brands I mentioned earlier, all of which are solid. RBH, Ascend Acoustics, Outlaw Audio, Hsu Research, Paradigm, SVS, JBL, Revel, RSL, Philharmonic, among others. As I mentioned before, I think bookshelf speakers would make more sense in that situation than towers, although if you cranking the volume really loud, tower speakers might make more sense, although there are bookshelf speakers and LCRs that can still handle wide dynamics, like the
Hsu CCB-8,
Ascend CMT-340se,
RBH R-515/
R-515E, etc.
For subwoofers, I would look at what can be had from Hsu Research, Outlaw Audio, SVS, and Monoprice Monolith. For AVRs, I would look at offerings from Denon, Marantz, and Yamaha that fit your budget and criteria.
