Thanks guys for the kind words
The dance floor is about 20' x 45', kinda long in shape.
We're supposed to have a photo shoot done in a week or so and I'll post them as they'll be much better then my photos, but for now I don't have too many. I used 12 - 18" custom horn-loaded sub cabinets (2 in each corner and 4 in the middle for fill).
shihp001: If you're interested I'd be more then happy to sell you a plexi tweeter array, loaded or unloaded. The ones pictured are loaded with Beyma CP22's and the plexi is milled specifically for the bolt pattern on this tweeter. They sound really nice imo. I can also do the plexi in color, but I choose clear for this job.
Just shoot me an e-mail: firstname.lastname@example.org
