I just picked up a set of JBL 2241H 18's in home made folded horn cabinets that are 2' wide by 3' high by 3' deep at a pawn shop for $355 out the door. The cabinets rattle some but its nothing some good glue and a finishing nail gun can't fix. We currently have an 18" Kilomax in an oversized ported cabinet (just over 9 cu ft and ported around 32hz) and will be getting a second one soon. My question is will they work well together or will there be conflicts/cancellations? They will be running off the same amp if that matters.
