his bass. He said that, as far as sounding like a musical instrument
goes, his Ampeg cabinet with six or eight speakers sounded better
overall, but he just _wanted_ to have a bigger speaker than anyone else.
And this was even before Spinal Tap.

The 30W was an interesting beast. Back then, voice coils and suspensions
did not allow a very wide xmax, so if you wanted to move a lot of air you
needed a lot of area. The T-S math hadn't been worked out back then, either,
so cabinet tuning was more or less trial and error and nobody really had a
grip on driver Q. So, by the standards of modern bass drivers it was pretty
crappy.

But, if you wanted a box that could move air at 20 Hz, you could do it with
a 30W in a huge sealed cabinet, like they did for the Sensurround system.
Want to put it in a small cabinet to carry around with your bass guitar, you
are going to find the Vas is not appropriate for the application.

And anyway, the lowest string on the bass guitar is what... 65 Hz or so?


You're thinking cello. Bass goes down to 41.something. But yeah, it's far
from 20.
