[QUOTE="keep_hope_alive, post: 8090729, member: 576029"] i didn't post enclosure response curves (calculated) but the SPL tuning will burp louder at 45Hz (or so) than the SQ tuning. I agree we want to operate the sub ABOVE the tuning frequency. that port will be removable and adjustable for post-construction adjustment. the angle was on purpose, the end result will be a horn built into the rear of the van (and removable).
