Assumptions
Small dimensions, high SPL, packs doesn’t have to play basses that can shake to walls, Angle lower than 45*, “pro” finishing.
Casing
Project for Turbo sound listeners, some dimensions are different but angle of depression is the same – that means 35*. Casing made of leaf- splice, waterproof, with 12mm thin. I used glue and screws. Spatula finishing, painted with nitromal. Steal on front. At bottom side are 2 speakon neutrik slots and two runners. Casing is 30-40 liters capacity, and is tuned for +-40Hz. Why more or less? Casing should be as small as is possible, but with capacity fit to 2 speakers 12” that don’t play with low bass. Tune is set to get nice sound without noising.
