Subwoofer recommendation for Maggie 1.6 QR

Again...Rel and Sunfire...these are the only two subs I would consider if I had Mags...my buddy has the 1.6s with a Rel Storm...and like many have said...they mate very well...the Sunfire is a little more aggressive sounding...but very tight and musical...either way...u will have a killer system..good luck...

Has anybody tried the HSU Research subs with a 1.6?

i have the psb 6i and the definitive technology sub 8 with my maggies.
they sound very very nice and tight

I had similar setup with 1.6s and I used 2 Martin Logan Dynamo subs. It gets you to 25Hz. This is the entry level sub of theirs. It integrates decently at low levels. Others in their line can get lower than 25Hz according to specs but I have not heard it.
