better bass than 50hz? -Bob Bernstein.

The problem you have is too much 50 Hz. If you have an 8-foot ceiling you have
the axial length and width moded stacked up at 50 Hz followed closey with the
ceiling mode at 70 Hz.

But you will get wonderful lower frequency room reinforcement below 50 Hz (12
dB per octave as frequency falls.) However because you have so much at 50 Hz
you just can't appreciate the lower stuff. If you think about how deep your
voice sounds when you sing in the shower you get an idea of how bass works in
small spaces.

The smaller the easier it is to get bass. In a small room however, especially
with identical dimensions things get complicated by the modal range. In yourt
case the modal range starts at 50 Hz and runs to about 300 Hz. In a medium
sized room it usually starts around 30 Hz and runs to 300 Hz.

In a car the modal range is shifted up an octave (60 too 600 Hz) which makes
it easier to get low bass but complicates acoustics in the midrange.
