I obviously disagree.

I use ETF5 software with my PC and Radio Shack meter to look at freq response in my room. And how can I say this: it does the measurement "fast enough" that there is not enough time for room resonances to occur. (There's a word for what it does, but I can't remember at the moment.)

It's easy to see the benefit. Without eq'ing (and I actually only go after the worst peak), I'm +/- 7.5 dB from 20 to 200 Hz. With the eq, I'm down to +/- 5 dB. I've had up to 5 peaks attenuated in the past, and I can get to +/- 3.5 dB, but in my book, simpler is sometimes better.

Shoot, even SVS recommends eq'ing for sub interactions with a room. And they *build* subs for a living. They probably have a little bit of an idea of how they interact with the room too. And Velodyne incorporates an automatic eq'ing system in their new Digital Drive subs. Not 1/3 octave: parametric digital eq's with precise control over wavelength, bandwidth, and amount of attenuation.

We all know placement and room treatment is the best way to deal with this stuff. But failing that, a parametric eq is a very acceptable way of dealing with sub (low freq) room interactions.
