Challenging Speaker Situation

a pool table calls for serious music..this is serious stuff...get a cd jukebox...yeah, a big ol' jukebox.

Good question. First since this is a billiard room, you'll be moving around as opposed to sitting in one place called the "sweet spot". You'd be surprised how much the sound can change by simply moving away from the sweet spot. So in my opinion (if I were you), I'd set up 4 identical speakers in the 4 corners of the room and run them from either a two channel powerful amp/receiver with A+B speaker outputs or a 5.1 A-V receiver that has a 5 channel stereo surround sound format. Your room would be considered large so look for full 3 way floor standers rated for "larger" rooms.

Another approach would be to install 4 bookshelf type speakers up high in the 4 corners with a powered subwoofer somewhere on the floor. There are some powerful high end bookshelf or standmount speakers such as the B&W 705 or 805S. There's no shortage of them. I'd work with a local hi-fi store to be sure you select the correct size subwoofer for your size room and you're employing enough power for this size space. If you like a lot of drum slam and punch and you go the way of bookshelfs, consider the size of the mid-range/bass drivers. May be better to get them in the 7" diameter area as opposed to the typical 6" or less since you listen to rock n roll and jazz.

This would be my recommendations. Sounds like a fun project. Would love to hear how you make out.

How about 4 corner horn Klipsch ??? That would sound awesome in a Pool Room.....

I like the Klipsch corner horn idea for this application in particular in order to keep the speaks optimally positioned but out of the way when shooting. 2 corners should be enough though.

An unusual selection might be the pro-type Toa HX-5's with a sub. Probably the best speakers I've heard in a public setup. Each speaker is actually 4 hinged together and have versatile mounting options.

What's your budget?
