I think it's funny people are more interested in the weird things they see in the background Here's the quick-n-dirty.
The arrays each have 16~5" midbass and 32~cone tweaters. All were buyouts from parts express. I also have two bass bins with 2~10" woofers each. The big orange box also is a 15" horn loaded sub. After 2-blown drivers, It's been put out to pasture. It used to rattle stuff off the shelves when it was working.
It currently runs with 3 amps (used to be 4), and dedicated Linux computer that does real time audio processing. Crossover, parametric EQ, and other goodies if needed.
Long story short, It's a giant MP3 player. Many of the array drivers are at the end of their life, a couple dead drivers, and surrounds are beginning to rot. Since the speakers were limited buy-outs, I can't just replace the dead drivers. I need to re-design and build a new array. Like everything else in this thread, not enough time to do it.
