You can have two of these parameters, but not all three at the same time: small box size, frequency extension, and efficiency.

here are the specs for my hgsII-18 thx ultra2:
cabinet size (h/w/d): 23.5"x21.25"x18.5"
frequency response: 15Hz-120Hz +/- 3db
harmonic distortion: less than 0.5%
subsonic filter: 15Hz or 35Hz
High Pass Crossover: 80Hz or 100Hz (6dB/octave)
Low Pass Crossover: 40Hz-120Hz (12 dB/octave initial, 48 dB/octave ultimate)
Phase: 0deg/180deg
Amplifier: Class D, 1250 watts RMS, 3000 watts peak
Woofer - forward firing: 18" (15.2" piston diameter)
Magnet: 220 oz (13.7 lbs)
Magnet structure: 380 oz (24 lbs)
Voice coil: Tandem 3" push-pull
Inputs: Line-level, Balanced & speaker-level
Outputs: Line-level and speaker-level
Weight: 115 lbs (approx)
considering that (above) and their "ultra-efficient" amplifier, id say that that theory goes out the window.
