Yes, these are the subs that I got from my daughter after I gave her my KEFs. Was going to try and sell them for her but I think I'll keep them for my den. Maybe try one in combo with the SB2000Pro. I have my Umik mic on a stand and laptop connected to my AVR. Just need time to review the REW video before making any measurements.
, the build quality on these looks to be pretty good. It took the protection circuitry a minute before they would turn on the first time, but they had been stored for months. I have them set to auto now and they power on and off as expected. These have spun aluminum 8.5" drivers, are ported and have curved metal grills. The grills slide into a groove and have soft pads in several locations so that they don't rattle. Box is MDF and there is a gloss plastic trim on the front to hold the grill. They look nice for what they retail for.
Lots of controls and connections on the back. There are two levels of room compensation (normal and narrow) and two levels of auto-on sensitivity. Level control runs from -54dB to +12 dB. Crossover range is 55Hz to 200Hz and phase is adjustable from 0 to 180 degrees. There are two sets of RCA and speaker connections, both input and output, so these can be easily daisy-chained without any Y adapters. They retailed for 480 Euro or about $550 USD in 2015. They are rated from 25Hz to 200Hz, but I think that's pretty decent given the size of the driver and cabinet. I would not have expected these to go down to 20Hz.
Too early to say how they compare to the SB2000Pro. Had them playing back ground music most of the day today, so nothing with super deep bass, but enough to keep them humming all day. For the typical alt-rock that I listen to they do very nicely. Had the system running at around 90dB last night and did not notice any strain from the subs. I have yet to try the resampled songs Pogre recently posted in the subwoofer candy thread; those will be a good test.
BTW, do not place your subs in front of your mains. The reflections off of the tops were so bad I had to place cushions on top.
