Here's a rough calculation I just tried:
1. Estimate RT60 for a 9 x 10 x 8 residential room with carpeted floor and a few windows on one long wall: 0.44 seconds.
Reverberation Time Calculator
2. Calculate room cutoff frequency using Cf = 20000*SQRT(T/V): 494 Hz
"Every studio has some frequency above which the modal frequencies are close enough together to merge into a statistical continuum... At frequencies higher than [this] cutoff frequency, various components of the signal will be treated more or less uniformly... At frequencies below cutoff, excessive spacing of modes exists with resulting uneven treatment of signal components."

This calculation suggests that you'll have smooth sailing above roughly 494 Hz, and you can try treating the room with bass traps and diffusers to smooth out many (i.e. 20) individual modes below 494 Hz. Lower frequencies would generate more harmonics (modes) below 494 Hz, which I think is why bigger speakers and subwoofers might be problematic. I never tried to aggressively treat my small room, but going to nearfields with higher cutoff definitely helped.
Ouch, my brain hurts and that's all I got.
Perhaps some experts in the Studio Construction & Acoustics Forum can assist?
