Lack of low frequency response

[Richard Brekne]

Hi folks.

Just a general question I would like some thoughts on.  What are the
major reasons for a soundboard not having very good low frequency
response.  I've heard several makes from former eastern Europe...
Zimmerman comes to mind right away.... with a particular kind of nasal
sound to their instruments... and I've come to the conclusion that this
sound often corresponds to a panel with poor frequency response under
say... 300 hz.  Like turning down everything below 300 hz on a stereo
system... turning up the midrange... and leaving everything above 2000
hz alone.

I'd appreciate some thoughts on the matter.

Cheers
