Oh, it hasn't ever really worked. Haha. :p I've never been able to "floor it." My original plan was to do a dual build but I only partially finished one and I've been gridlocked for quite a while and...

I've moved this sub several times. In 3 locations I had to take the door off the hinges AND remove the caps to get it through. My current location has nice doors so I only have to take the caps off.

Hmm. The tools I had when I built it are long gone. I'm wondering what I'd have to do to re-trim (and re-paint) the caps. I don't want to have to take the driver out or anything :serious:

I built a sub with a 32" tube thinking I wouldn't have any problem getting it through doors (30" would have been the best choice :D). I suppose if I shaved the caps down flush with the tube on the...

Advanced, dynamic subwoofer/bass calibration

So I have a sort of makeshift solution (and have had for years) where I use a BFD. I usually leave it set the same for all listening levels, so it ends up being bass light at low levels and bass...
