I posted earlier in this thread, cautiously because I thought I would be inundated by ... ummm... something. No responses so far. So if you're anywhere near NE Tennessee, about 90 minutes east of Knoxville, 60 min north of Ashville, 30 min from Bristol....I'd be more than happy to audition my....
Dual HSU MK3 v3, tweaked to the best of my ability, desire, and time. To me they sound incredible. No negativity toward any other sub manufacturer here... but you wouldn't see this post unless you weren't happy with what you have...

I would be more than happy to (show off) exhibit what HSU can do in MY room. YMMV. I'd like to hear other subs, (just none better

Currently running HB1 mk2's x 4, with a HC1 mk2 center, through an Onkyo 707, output to an Emotiva UPA-5 (125 watts x 5 channels). I do have a pair of Polk Monitor 70's (previous fronts), a pair of Monitor 50's (rears) and a CS2... I'd even be willing to hook up for a serious 'about to purchase' AVS user that's local and would like to hear a Polk set-up (yes, it's for sale...500 obo, just for the Polks).
Of course, I would like to communicate through AVS before opening up my home.... safety.
Hope it helps, Joe
