Great sub...

What a terrific match to my BM12 MkIII monitors. Those monitors have even more top end now that I've reduced the low end load. This sub gets low...and with conviction...and I'm still breaking this little beast in. It leaves you wondering just how such a small sub can do what this gem does. My Hsu VTF subs (down and out...acting as supports for the BM12/Isoacoustic stands) were no slouches, and this BM14 works as well if not better than the Hsu's did in their prime. I've got a Presonus Temblor T10 paired up with some BM5 MkIII monitors in another room. That's a fine sub too, but the BM14 is just more visceral to me. I'm sure the room differences as well as sealed vs ported aspects are at play here too (Given the price diff I'd have to consider the T10 one heckuva buy). Still, I had no issues placing the BM14 and the marriage with the BM12's is about as good as I could've hoped for. I definitely recommend you try the BM14S out if you've got the low end need and a budget that can stand the price of admission. By the way this was my first Sweetwater purchase and I have to give a shout out to Nathan Wall who was quick to let me know he there to answer any questions I might have with respect to the sub. It's easy to see why this company is noted for their great customer service. I'll be purchasing from Sweetwater again!

Great, musical low end in a compact sub!

I'm very happy with My Dynaudion BM14s, In my room I measured a -3 of 18Hz and +-0 of 20Hz (TrueRTA with Earthworks m23 at main listening position). Nice! Having 2 really evens out the room response. I'm very impressed with the low frequencies acquired in such a compact sub. I'm also impressed with the musicality, the sub doesn't just shake the room it plays the note as it was recorded. Isoacoustic stands not only isolate but get the sub of the floor a few inches helping to keep the sub safe.
