Speakers for the party system


Twice a year, we host a gathering of around 120 friends for several days. Across the years, we have gotten much better at supplying food, beverages, camp sites, showers etc. The issue is music for wild dancing! Until last year, we used the main floor of our house and our reference level sound system. Everyone was very happy but me... I always worried about spills, chills and expensive thrills. Last year, we finished the basement and moved the party downstairs. The room is almost the same size (900 sq ft), but with lower (9 foot) ceilings. I bought a fairly descent system, but the party girls wanted much more punch and thump. Can anyone recommend a reasonably priced speaker that will really fill this room with booty moving magic? I've noticed some good deals on PSB scratch and dent stuff but have never heard these. My main system uses Dunlavy V with Plinius SA-100 monos, so the competition is fierce. Song selection includes everything from Mikey Hart to Mojo Nixon, Parliment to Massive Attack, The Beatles to Lou Reed...

I have had many speakers in the past few years including Martin-Logan Quest, Duntech Princess, Magnepan 1.6's, and Coincident Partial Eclipse (current). My favorite all time party speakers are Klipsch LaScala's. They really crank with a flea powered tube amp and sound quite good. You would probably need to add 1 or 2 high output subs because the LaScala's don't reproduce the bottom octave at especially high SPL's. Everything above 50Hz can be reproduced at ear splitting levels and if you buy an older pair they can even be used to set drinks on, bonus...
So you wanna party down... get yourself a used pair of Klipsch Cornwalls or Khorns and shake them walls....add a Velodyne sub if you want to shake the neighbors walls and set off car alarms. The Klipsch alone will get plenty loud with bump to spare.
instead of replacing lovely dunlavys think about building up another pro-dj setup ~$2000 worth solely for parties i.e. some pro JBL monitors with built-in crossovers driven by some huge-ball parasound mono amps...
i bet you'll find a plenty of 900sqft space to place another system.
