Can you give a month when the SB13 ultra will be ready to ship? I was thinking of getting the SB12 then doing the upgrade thing you guys have for the SB13. I need a new sub badly. My current def tech sub has output to only 28hz. I like the way it sounds though in my 1500cu ft room. So either the 12 or 13 is going to be huge improvement.
Also i saw the audioholics review of the SB12 and it was tested to have output to 21hz- http://www.audioholics.com/reviews/speakers/subwoofers/sb12-nsd-subwoofer/sb12-nsd-measurements
The SB13 review from S&V says it has output to 23hz- http://www.soundandvisionmag.com/article/review-svs-sb13-plus-subwoofer?page=0,2
Shouldn't the SB13 measure lower than the SB12? Or this because of different testing procedures?
What kind of output can i expect from both the SB12 and 13 in my 1500 cu ft sealed room?
(I do have windows though)
We did massage the DSP EQ file for the SB13-Ultra, and the tentative FR spec is 22-350 Hz +/- 3 dB. But the bigger story when comparing the SB12-NSD and SB13-Ultra is the shape of the knee and the subsequent roll-off slope. The SB13-Ultra has a broader and more gradual knee and a shallower roll-off slope. This results in less phase change with lower group delay, and it will also take better advantage of available room gain. So in 1500 ft^3 room, the SB13-Ultra will dig deeper than a SB12-NSD.
In terms of max clean output, the SB13-Ultra has about 2X the max clean output (i.e., CEA-2010) as the SB12-NSD, so add about 6 dB to the values showin in Josh's SB12-NSD review and you'll be close. Estimating max SPL indoors at the listening position is more tricky, because of room modes. With that said, each nearfield boundary will typically add about 4-5 dB of additional output, with the ceiling adding maybe 2 dB. Room gain will add about 6-8 dB/octave of additional max output below the modal/pressure transition frequency in the room (probably about 35 Hz in your size room) - so additional max output from room gain is frequency dependent.
We should be taking pre-orders in August and shipping in September. We already have early production samples in-house (see our FB page).
