Here is one....
Generally speaking, it is not a good idea to throw speakers everywhere--and a really BAD idea if they operate in stereo. Not sure how well simulated surround works at high SPL levels in a large room--have not tried it. I do know that consumer speakers driven at rock star levels tends to blow them up quickly. Yes, I have murdered a few speakers back in the day.
To avoid that, I used PA speakers for rock star mode and regular speakers when competing with the local night clubs was not on the menu.
Basically, the key to getting high SPL out of a speaker at low distortion is to use a very, very efficient speaker which tend to be very large, very heavy and cost quite a bit. After all, those giant speakers used in clubs, theaters and arena sound are not that large for style. There is a thing called "Hoffman's Iron Law" that applies so best to get familiar with the limits of speaker design.
The Titan 630 XL listed above is one of those high SPL/low distortion speakers--think around 125dB at one meter. I'm sure the single woofer versioon would be fine, you would "only" get a bit over 120dB at one meter but that is good enough to meet the members of local law enforcement.
Other very high output speakers with clean sound are JTR, some speakers from Seaton Sound, actual real theater speakers (JBL 4722N for example) and the SH-50 speaker from Danley Sound Labs are of note. Another good option that would be considerably smaller is the PSA MT210, when used with subwoofers they should split your wig without breathing hard. Be aware the above speakers are not small, they are not exactly pretty (unless you pay for custom cabinets for Danleys or Seatons. Since big and heavy = money, they are not exactly inexpensive either.
Be aware what you are attempting to do is more of a pro audio thing, not a consumer audio thing. That all depends on what your SPL requirements are, your room acoustics and so on.
Be aware that if you have high efficiency speakers and require high bass SPL subwoofers--the subs will generally be very large or you need to stack piles of consumer subs. Wall outlets have electrical limits so you will need to know how much bass SPL is required before moving forward. I can throw out an Eminence 21 inch pro sound subwoofer in a 16 cubic foot box getting massaged at 2,000 watts of power each--four of those would do nicely but you might need more electrical service done to provide the level of power those big pro amps consume.
If I was you--I would try to find a place that rents PA/pro sound gear and rent a system in the size that you can put up with. Start off with two mains and two subs tuned to around 30 Hz to start. Rent them for a weekend and you can get a real world idea of what you need. Be aware that they will be very loud/efficient so any consumer speaker will not get to that level of SPL. Just a hint to know what you are dealing with and what is available.
Good luck in your quest!
