The Crescendo (Grande) Speaker System

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.

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.
