    I think my first encounter was a Sunn 200 bass amp with 2 JBL D140f's. This was in the '60's I was playing bass in a rock band using a Gibson EB-3 (Short scale) and a Vox Essex amp. Dissatisfied...

    Derek;

    If it were me, I wouldn't carve up the L 150. Its kind of like finding a cherry 1953 Olds Starfire, and the chopping it up to make a hot-rod. It has been a long while since I heard a pair...

    Hi Bedrock,

    I think that you have improved your design considerably, but I agree with Speaker Dave regarding the larger box. If you note his examples of later use of the LE14, they are all 3+ft3. ...
