I am currently writing a speaker enclosure design program with a nice
user interface, but it is for MS-DOS.  I have no plan to support the
Mac.  This program, SPKR, supports computing the enclosure volume,
dimensions as well as vent dimensions (for a vented system), given the
Thiele/Small parameters of the woofer.  It supports 2nd order closed
box systems, 4th order vented (in three alignments), and 6th order
vented (also in three alignments).  A frequency response plot can be
displayed.  Driver and enclosure design data can be saved/retrieved
to/from files, and parameters can be altered via a simple menu-driven
editor, to view changes in enclosure specification (and system bass
performance) virtually on-the-fly.  Context sensitive pop-up help
screens are available.  SPKR will be runnable on MS-DOS 3.x systems
with a Hercules-compatible monochrome monitor, and it supports full
color on an EGA or VGA-equipped system.  A minimum of 256KB of memory
is recommended.

I am wrapping up the final coding, and will soon write a complete
manual for it.  Once that is done, I welcome any speaker system
designer/builder to beta test it.  If you are interested in becoming
a beta site, please contact me at the e-mail address or voice number
listed below.  At this point, I have not decided whether to release
it as a commercial product or to make it shareware.  Your suggestions
are appreciated.
