What Speakers to use in a bar/restaurant environment


I'm looking for advice as to what speakers I can install on the walls or suspend from the ceiling of a bar/restaurant. The current ones sound lousy, not clear at all, compared to what I would like. There are many 70/100 Volt systems on the market, and I assume they make quality speakers at a sane price level.
I'm looking for mainly background music, but I need the ability to get suitable volume for events like a UFC.

Would it be worth considering smaller home audio speakers for this type of environment, or do I need to install "commercial" ones such as those made by JBL, etc?

And advice or direction will be helpful.

The rooms are ~3000sq ft, with a 14 foot ceiling.
Want to get a very nice quality of sound with low /moderate volume .
brrgrr
Heard a bose commercial system the other day while I was at a church.
Pretty awsome.
The local red lobster here has posh speakers with passive subs flown from the ceilings, and I have to admit, it sounds pretty good.
I have been to many bars & clubs in my lifetime (believe me!), and most sound like crap.
There is a small bar here in town that has a total Onkyo system with a seperate transformer (step up, or down, I don't know.
They use about 6 pairs of onkyo speakers (don't know the model #), with 8" woofers, a mid and tweet.
Pretty good sound really.
I don't care for the Klipsch for the price.
I like them in home, but a resturant I frequent uses the outdoor type klipsch 2 way (6 1/2"), and a home amp (yamaha), and it sounds horrible.
The local Hastings record store here uses pro equipment (2-samson amps, samson preamp, and JVC 5 disc player), and it sounds pretty good also.
They are running about 10-12 pair of 8" in ceilling coax speakers, and it actually sounds pretty good with good mid, highs and decent bass.
Best public system I ever heard was at the Tiki room at Disney land in Aniheim, Ca.
I asked (had to ask 3 different employees) what kind of speakers they used (obviously subs), and the guy said they were BagEnds.
It sounded freaking awsome.
Very Pricey though.
You could definately get away with consumer electronics, if you were to go with powered speakers.
May save you some money also.
Behringer, alisis, and many others offer reasonable priced powered speakers and subs.
