Want fatter, non-flat bass? Crank the tone control.
While I don't see him much on this side of the forum anymore, it was bossobass who first opined that our relative insensitivity to the deepest bass frequencies is already
compensated for in HT source material by the mastering/mix engineers. They mix the audio track so infrasonic (or near infrasonic) content is a level which sounds flat/level/even to our ears, and additional correction/compensation is therefore unnecessary.
The key limitation to the above is that the bass will only sound balanced at a given playback level (typically fairly loud) and won't sound that way at lower volumes, which was the basis for the house curve concept. The problem with a fixed house curve is that it will also only sound correct at a given playback volume.
This limitation of the fixed house curve ultimately spawned the development and release of Audyssey Dynamic EQ, which (as the name implies) has an EQ curve which changes with playback level. Dynamic EQ is very well conceived and works extraordinarily well in actual use; the house curve is always perfect, no matter what the playback level.
So I definitely recognize the need for a house curve as Spyboy suggests, but I eventually found the limitation of a fixed house curve to outweigh its usefulness. Now with Dynamic EQ, consumers can enjoy the benefits of a flat subwoofer response at higher playback levels, and then also enjoy the benefits of a customized dynamic house curve which works equally well at all lower playback levels.
