Just how much pressure is there inside a ported line array enclosure with eight 7" drivers? is 3/4" MDF enought to handel it ? I've just finished building Rick's RS 8 array and tested the sides and back panels with a stethoscope and god I have so much vibration in those , at some frequencies they emit as much as the drivers themselves.
Any recommendations ? I'll go as far as rebuilding the enclosures with more bracing than the recommended vertical bracing .I know Rick's curved back panel enclosures are much stiffer than the square box , can we obtain the same stiffness and damping with bracing or double panel and sand filling(why bother with weight they are already very heavy)for a rectangular enclosure?
thanks
JP
