too good
these monitors have fantastic low end, the best of any 6.5" monitor I've ever used. They're clear and detailed when driven by high end converters. They're powerful but sound good at low volumes. Lots of thoughtful fine tuning on the back which coupled with price point makes them a perfect home studio option. Top end? Whoa, its detailed. They seem to have a slight midrange dip which is not a problem but I don't personally like it. They also throw a really wide and diffuse stereo image so I wouldn't mix on them without another playback system. I actually am using them mostly for tracking ebcause the sound off axis sitting at a keyboard is so sweet versus my preferred passive tannoy and yamaha mix monitors that have a small sweet spot because of their accurate stereo imaging. Coupled with an NS10 or PBM6.5 and amp setup I'm really happy with these. I have the big sound for tracking and checking a mix and I can also use my midrangey, directional passives to really get the balance right. Its great to switch to these when soloing in place to get a really detailed and defined representation of a sound that's not sitting, make some tweaks, then go back to the B setup and listen, then un-solo. I highly recommend these for a small room. These replaced my trusty Events that have served me since time out of mind. Never looking back.

they're officially rated down to 39Hz... do things seem solid all the way down to 39? How fast do they disappear after 39?
41029
I've not measured but with the flat amp settings I'm really hearing deep bass extension I usually use larger woofers and 3 way cabs for.... one fault is the bass transients aren't fast if you're used to NS10s but they're n par with other ported bi amped designs

Great frequency response out of a 6.5" driver
I've used alot of monitors, from the KRK Rokit 5, 6 and 8, the HS5, HS7 and HS8 by Yamaha, as well as the Sterling MX8, Mackie MR524, MR824 and CR3 (not acceptable for any studio imo, but good for starting out) and these monitors have AMAZING depth and clarity for their size. They have a lot less harsh mids than the HS8 in my opinion, not in the sense of lacking mids, but flatter and smoother response. Even the HS8 has a slight bit harsher midrange than these, I use them as my daily drivers for monitoring. Easy 5 stars.
