Well... I changed the enclosure net volume for my BL-18 by -.5ft3 and if it gained I cannot tell. I'm still getting that sound at 44hz and above. I'm throwing darts at this point... lol. This is uncharted territory for me, I suppose I might be asking more from my sub than it's got possibly... idk... I'm clamping well above rated (3000+) and even with the additional spider it's possible it is well past the limits. I'll try another -.5ft3 change... my tuning will be around 42.5hz then so if this won't let me burp at cabin frequency (47hz) I think I've passed the subs mechanical limits. Everytime I downsize the box it lowers the impedance around tuning so I might negate the changes with additional power anyways. It looks like .5 rising to 1.4 if I go .5ft3 less on volume but hell... I'm gonna find out...
