Recently, I completed building a 2x8 cabinet in the chamber of horrors. It's for URB duo or trio gigs where a little sound reinforcement is needed. I wanted something small and fairly lightweight. Eminence makes a nice 8" speaker - the Beta 8cx. This is a coaxial speaker, so the tweeter attaches to the back, saving space. They also make a crossover for it that has speakon, 1/4" jacks and a tweeter level control all in one unit. All the parts cost $260. The finished box is 19-3/4 x 9-1/2 x 14-1/4 and weighs 30 lbs. I made a vented box of 3/4" cabinet plywood and painted it green. (WHY?) It was quite easy to build. It's been used on one gig so far and seems to do what I want. Response is pretty even and natural. The tweeter sounds good - not too harsh. It's wired 4 ohm and each 8" is rated to 250 watts, though I wouldn't want to push them that hard. I can provide more details on construction, if anyone's interested.
