For the most part you can't detect distortion below 100Hz. That's because distortion occurs in the harmonics, so 60Hz distortion, for instance, is heard at 120,180,240,300Hz etc. That doesn't mean you can ignore distortion in subs, though. because driven past xmax the driver itself creates those harmonics. Even below xmax long excursion will create Doppler distortion, as was well documented by Paul Klipsch. Getting the highest possible SPL from the shortest possible excursion is the reason why horn loaded subs have low distortion figures that direct radiators can't approach. Add in the low pass function of folded horns that filters out above pass band harmonics and one can understand why they give unrivaled results.
