ErgoSonic Bass Drum Size Advantage
Replace a larger conventional bass drum with a smaller diameter ErgoSonic Bass Drum
The sizes of ErgoSonic Bass Drums and conventional marching bass drums are not equivalent. Our drums have
greatly expanded tuning capabilities due to the size of their resonating chambers and the ability to independently
tune and dampen the resonant head. We’re happy to help you find the right size drums for your ensemble.

The size of the resonating chamber helps determine the potential pitch range
of each drum. As the size of the resonating chamber increases, so does the
potential range. Since our drums have larger resonating chambers than their
conventional counterparts, a smaller diameter ErgoSonic instrument can
replace a larger conventional bass drum. That’s why it’s not necessary for us to
make a 28 or 30 inch drum!

ErgoSonic Bass Drums are the first and
only marching bass drums with
independently tunable resonant heads.
This allows each individual drum to be
tuned to a wider range of pitches and
significantly expands the potential range
of your entire compliment of ErgoSonic
Drums!
The option to port the resonant head
extends the tuning range of the drum
by lowering the pitch slightly while
creating additional venting. The port
allows the air pressure to escape more
quickly, resulting in improved rhythmic
definition, articulation and clarity.
