Actually, it's not my interpretation (or misinterpretation
and need to "look more carefully"
as you so kindly worded it
) - it's Ilkka's own factual analysis of his own measurements posted in his own summary table in one of his own threads at the HT Shack that I was referencing and it has been updated with the newest PB12-NSD. Ilkka shows in this "CEA-2010 max clean RMS output" summary table that the new PB12-NSD outperformed the VTF-3.3 in max extension mode by +4.3db
ultra low-bass average (20Hz-31.5Hz, SVS@104.3db vs. HSU@100db) and +2.2db
low-bass average (40Hz-63hz, SVS@110.9db vs. HSU@108.7db), and even outperformed the 3.3 in max output mode in low-bass average by +.7db
and virtually equaled it in ultra low-bass average (SVS@104.3 vs. HSU@104.5), yet in that max output mode the 3.3 is only managing 85.5db @ 16hz while the PB12-NSD is still delivering a powerful 96.9db@16hz - an SVS advantage of +14.4db
in that mode comparison!
Oh, and I notice you did not want to discuss Ilkka's distortion measurements comparing the two subs - I don't blame you
So the current PB12-NSD with new amp provides all of the overall dynamics of the 3.3 in max output mode while simultaneously delivering all the 16hz performance of the 3.3 in max outpt mode, less distortion, exceeds its SQ to my ears in my subjective listening tests, and does all this at about $100 bucks less than the 3.3 - by all unbiased no-spin observations SVS has a winner here!
Ain't competition a great thing folks?
It certainly is for all of us subwoofer consumers
BTW Pete, if you feel Ilkka has erred in how he measured your 3.3 and have a beef with the numbers he published for all to see, then perhaps you might want to take that up with him...
Best regards to you,
