Thinking of building my own cab to replace a Hartke 35 combo amp. I love the simple looks of old Bag End amps (s12b-b) and I also totally love the look and the wonderful reviews of fearfuls 12/6. Which has me wanting to make a simple single 12 inch speaker cab with a kappa lite 3012 (or LF version) with a front vent similar to the Fearfuls and Eden cabs. Sizewise we're talking 65cm height, 41cm wide, 38~9cm deep. So, any thoughts on 1: 3012 vs. 3012LF 2: how wide to make the vent on the front? 3: can this be made without a crossover? (Really don't want one). Thanks for any creative help and comments.
