so im working on that monster 24x22 bassdrum finaly, and im loving the sound. its insane, but im thinking about building a sub-woofer too. ive heard a few kits with them, and like the sound alot, i dont really mute my bass any and stuff it full. generaly i run it wide open(no muting inside it) at the most i may throw in a small throw pillow(maybe 6inx6in) and call it a day. but im thinking a sub may help me push that sound even further, but i have not the slightest idea on how to tune one of those things. like-wise im also looking for the sub mounting hardware for in case i do, and its bloody hard finding that stuff in the same brass finish im using.
