Hello Bill,

Placing even an excellent quality driver into an arbitrary speaker box
without consideration of box volume and the 'Thiele/Small' driver
parameters (from memory, I think they are Vas, Qts, and fs -- but it has
been many, many years ...) will likely produce very disappointing results.
That is especially true if the box is ported as opposed to sealed because
the tuning of the port/vent is critical and will have a significant effect
on the ultimate frequency response and 'Q' of the system, particularly in
the lowest octave.

No doubt all of that critical system design work has already been done and
optimized on the SP3!  ;-)

73,

Dale - WA8SRA
