I've been really looking forward to the subwoofer part of our eventual basement build, and I finally have made progress on that front.
I knew for a long time that I wanted to try a sealed approach this time, having had 2 different ported subs before (and currently). I thought I'd go for a pair of big ones, and when the opportunity came up last year I jumped on a group buy for a pair of Mach 5 / IST UXL-18s. These things are hand built in Canada by @mrogowski, and are extremely capable drivers. 34mm xmax, 1,200w power handling, 65lbs of woofage, and I now have a pair of them. :grin2: Just for reference, on pure displacement capability, I think a single one is capable of about 2.7 times what my Tempest can move.
I fiddled around a lot with enclosure sizes, WinISD graphs, and checking other peoples builds, and I settled on exterior dimensions of 20(w) x 20(d) x 22(h) for an effective net internal volume of about 3.3 cubic feet which should be very reasonable for this driver. I'll be using a MiniDSP on the pair in the final setup, likely working in a Linkwitz Transform to bring up the bottom end. Power will be from an iNuke 6000 (non-DSP), one sub per channel. Below is an approximate comparison of my existing SDX-10, Tempest, plain sealed UXL, and the same UXL with an LT applied.
