Quest for horn sound - Round 2 After the failure on my LE14a, I now redo the box to 4 cu.ft by remodeling the interior therefore I should have around 3.65 cu.ft after stuffing n with all speakers in. Boxes are tuned to around 30hz with 2 3"x9" round tube. Eh....forgot to tell. I have the boxes painted white too..Pics will come soon. All parts are in and I'm going to put up the crossover asap. Hope to taste the goodies from this proven design.
