Don't have a ton of specs, but: 15" hole 1/2" plywood 3.25 cf internal volume Two front ports. 3" in diameter and the tubes inside are 2" deep." Bottom left and bottom right. Does have a tweeter. Not sure on the crossover point. Needs to handle a 5 string tuned down a half step. Definitely prefer a more modern/open sound vs warm/wooly. I know it's not a lot to go off of, but just looking at that. What are we thinking? Delalite II? Kappa? Faital?
