Can Foam Really Absorb Bass?

[FrankDebro1]

I'm having bass problems in my control room and I'm using some expensive bass
traps in the corners that aren't fixing the problem. My buddy says he has some
Venus and Big Lenrd Bass Traps from Auralex and his room has been measured to
be as flat a project studio can be. He has spent about one quarter of what
I've spent. Can anyone attest to the Auralex Venus and Lenrd bass traps. Can
they absorb below 100Hz?

** Are you referring to the semi-religious faith folk have in the use of
1/3 octave pink noise tests for rooms as compared to "old fashioned" slow
sine wave sweep testing ?

A deep ( ie high Q factor ) room null or sharp peak will only show up in
its full glory in a slow sweep test.

How much money do you want to spend on 12" thick foam ? ;-)

This really deserves emphasing. No matter how crappy your room is now you
can always make it crappier. Either fix it right or leave it alone.

Yes, that's exactly my point.
