Massive speaker array.

This is the central speaker system inside Rupp Arena in Lexington, KY. It's called Big Bertha and I forget how much power that thing cranks out. It's darn loud though!http://farm4.static.flickr.com/3447/3224263219_c794dd80ca_b.jpg

Good grief! I'm sure it was state of the art when installed, but it looks ancient by today's standards. Almost reminds me of a Yellow Jacket nest. Thanks for sharing!

Wow, that is something else right there! That horn speaker style is quite outdated but is definitely visually entertaining. Thanks for sharing it!
