The speakers are all new. I built enclosures inside the cabinet and ported them out the back. They are composed of Pioneer 12" woofers, Pyle midranges and phenolic tweeters all running through Dayton crossovers. All the speakers are rated at 91db SPL.
I built a small computer using and Atom processor. It runs Ejukebox by Audiosoft. Everything is controlled by the touchscreen monitor built into the top.
The cabinet started out as an old, RCA console from way back in 1961. It was a dark, chocolate brown color with green speaker grilles. Really ugly. I stripped it, rebuilt it for the equipment and refinished it.
There are a few little bugs left to work out with the software and a little touchup on the cabinet but for the most part it is complete and sounds awesome. I can crank it up without distortion. In fact, it gets so loud that I can't listen to it above half volume.
Here are some pics. Hope you enjoy them.
