Elizabeth's First Loudspeaker Project:
Medieval with Ceramics !!!
She chose last summer's sale 3" Aurasound aluminum cone drivers.  The
left and right drivers share the box air space with a single side mounted port.
The doors on the side can be closed to subdue the surprising bass.  Brass
bars defend the drivers from inquisitive fingers (younger siblings).  She is
quite satisfied with the look and the sound.  The inside is damped with
heavy open cell foam (generic Black Hole).
The RED plot shows the port's output and the BLACK shows one driver (both were fed the same signal in this case, but one was smothered to avoid interference)
