build log for the box? is it ported in the back? 6th order? kind of hard to see

[Bsktbll895]

@01Ranga to be honest, I dont know what order this is. I kinda winged it on this box since I never built one like this and dont have software to design one. The panel in the rear of the chamber had a board that is interchangable so I can seal it off or add a port. Havent had time yet to test the tuning with it sealed. (2) 4" ports 14" long should bring it to 33hz, so I have some experimenting to do. According to 12volt.com, it is a "3 chambered single reflex bandpass". Someone enlighten me!

@Bsktbll895

if you seal off the rear it becomes a 4th order(single reflex) bandpass. if you port the rear it becomes a series tuned 6th order(fine tune with a front loading wall). try sealing the rear and see how it sounds then try it with a 3" or 4" aero ported externally at the rear and tune it low ;) i would also experiment with a front loading wall with both sealed and ported rear application.

@01Ranga Okay so I tried it sealed today and its a no go. Output is poor and the subs almost bottom out in the process. 4" areos are next. Wish me luck

@Bsktbll895

probably bottoming out cuz you need a loading wall up front. if you feel up to it cut out a square piece to cover the front and use 2 4" aeros or 1 6" aero and seal the rear and tune around 50hz. tho i would try using 1 or 2 4" aeros in the rear and tune around 30-35hz and see how it does, should do well.
