I have a pair of D123 in "Acousti Craft" cabinets. About 2 cubic feet with a retangular port running along the bottom. I love the sound, first JBL's I have owned. Mids and highs jump out into the room, wonderful sound stage, deepest I have had in my home. I think if I could get a bit more bass out them I would make an everyday speaker out of them. Ideas on modifing exsisting cabinet?

Or... Plans for the ideal cabinet for these as a single driver system. Exact plans with dimentions, port size etc. The cabinet disscusion have found here with all the techical talk are beyond my understanding, lol.

Thanks!
