George, they have two drivers in each cabinet. The sides are slanted outward toward the bottom, while the front and rear are plumb, it makes for a nice aesthetic. The slanted vertical sides are veneered, the entire inside and top are painted black. The front opening has cloth velcroed to the cabinet edge. The rear is open. He did a really nice job. He put soft Velcro strips under the amps so they can lay down on table or floor without scratching. The amp output wiring was simplified to eliminate the extra wiring harness and extra plug normally required to connect two drivers to one amp (the extra $10 for two drivers.) The amps have a speaker wire permanently connected to the amp output, and on the other end of thick OFC cable is 4 pole Neutrik Speakons to connect to the speaker cabinets, twist and lock, really nice part. He was a professional speaker designer in previous life, and an accomplished woodworker.
A funny thing happened when I picked them up. He had a bad back, I think he said from carrying these subs around. He made little caster rolling platforms for them so he could move them around without lifting after his recent back surgery. So while he was telling me to be careful lifting them, I lifted it and started to walk. I stepped on the roller skate dolly and started to slide, trying to stay upright, while holding this 60 pound speaker. I got my foot off the roller skate and when I put it down the skate had rolled to the new spot, so off I went again. I was thinking this is just like an old popeye cartoon, and "I hope I don't end up on my face with this speaker carving a hole in this nice wood floor." Eventually I got control and walked out, but it was a close one. The second cabinet his friend helped me load.
