What I can tell you is that parametric EQ is merely a way to boost or attenuate a specific frequency within a specific Q parameter and it is not limited in any way to which frequencies you can affect. A parametric EQ will be no more or less effective at 30 Hz than it would be at 20 kHz.
If you would like to read a bit about the specifics of our parametric EQ as well as the low bass adjustment feature in our subs, check this out:

Just let me know if you have any further questions, thanks!

Thanks for the link Jason. Some good info there. Helped me understand the parametric EQ of the Bravus subs.
After some more research into parametric equalization and MultiEQ, I think I was misinterpreting their statement. I think their point is that using parametric equalization alone to correct the entire frequency range 20Hz-20kHz is difficult to do because of the limitations of the technology (processing power and the spread of the frequency range). They go on to state that this is especially detrimental in the low frequencies where the long wavelengths are more susceptible to room acoustics.
Basically, having the parametric EQ in the Bravus subs is of great benefit to helping deal with room acoustics to mitigate "boomy" or "muddled" bass issues. This will hopefully be furthered balanced/corrected using the MultiEQ system.
At least this is how I interpreted the various sources of info. I think my head might explode if I try to understand it further.
























roll the eyes.
but more about dealing with post vacation bills, my upcoming NYS school tax bill (due Sept. 30th) and of course the ever present WAF.
