Off topic: speaker boxes

[Bill Clarke]

I shop at Amazon on a very regular basis. That said, I would never have
expected to find a huge assortment of speaker boxes listed. You can
populate them with the speaker(s) of your choice. To me this is
interesting, as I am getting ready to redesign my radio desk and am
thinking of a couple of SP-3s.

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
