Ok, indulge me with these experiments please Curtis... :D
(when you get time of course).
Max Extension Mode.
Turn your sub's volume up to 70dB using your pre/pro and an SPL meter.
What SPL's do you get for...
10, 15, and 20Hz?
If you have "The Incredibles", test this please.
(max extension, sub matched with mains)
Time 0:37:45 to 0:38:30
With an average SPL of 75-80dB and peaks in the 100-105dB range (using the RS meter in "fast" mode) what type of output do you get? Is the bass distorted, or does the sub bottom out at all? This is my weekend volume level which is about as loud as my favorite theater. The SVS bottomed in 12Hz mode at these SPLs.
SPL level is definetly an important number, just as frequency range, and a flat response are. If you can't go over 90dB without compression or the sub starts to distort at 25Hz, the accuracy of the sub is going to be poop unless you listen at 60dB and don't care about extension.. Now that I've experienced the difference a BFD can make, I think the biggest problem with speakers/subs not being "accurate" are huge swings in the FR. I'm not looking for 115-120dB reference peaks, just 100-105dB hits.
I'm definetly curious about what results you get! :confused: :) :confused:
