The Crescendo (Grande) Speaker System
3 Crescendo Enclosure Designs
3.1 Crescendo 2 Way
The Enclosure for the Crescendo System can be arranged quite
wide arrangements as long as the volume and tuning is preserved.
Here the design we use and recommend. It
uses a simple box with a large cross-section
port, to avoid compression and port noise.
The material should be void-free plywood,
18mm thick. Of course, Corian or Natural
stone or solid stave-glued hardwood, or
bamboo may also be used.
Glue with good filling properties is
recommended for any of the wood materials,
Grip-Fill (the professional version of liquid
nails) or similar work well, as can resin based
glues. Stone requires special glues.
The Back Panel is kept removable to allow
the low frequency drivers to be mounted from
behind. Unless you wish to use an external
enclosure for your crossover building it on the
removable back panel allows easy access for
modification.
We suggest to first try the box without any
stuffing or damping material. All the
resonance modes caused by the enclosure
dimensions are high enough in frequency to
not appear within the operating bandwidth of
the low frequency driver, mainly due to the
low crossover point.
