I have been using a REL Strata III sub with my TSM-MX's for a couple years now and am extremely happy with the match. The Stata is a sealed cabinet (as the Merlins), and I run mine out of phase with the crossover set to it's lowest point. Also have it wired using the speaker level input. Also note that my room is treated with ASC tube traps in critical corners and room size is about 16 x 17.
Bought mine here on AG a couple years ago for $700 and it was "as new" condition.
good luck,
tm
