Hello, Can anyone tell if there's some software for the Apple Macintosh for designing loudspeakers. I'd like to have a program to calculate for me bas-reflex and bandpass enclosures for me. A program to calculate filters would also be very welcome. I want to build a 6th order bas-reflex enclosure for a 10'' Philips speaker I have lying around but I don't have any article or book that describes the design well. So I'm kind of stuck on this project can anybody send me some information on how to build a 6th order box. thanks in advance, Hjalmar Dijkstra <A512HJAL@HASARA11> ps. I just bought some real ribbons in Bulgaria for the incredible price of $3.- a piece. They look a bit like Decca copies to me. The only thing is that I don't see a transformer with it. The units were manufactured in Bulgaria. Acknowledge-To: <A512HJAL@HASARA11>

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. -Ti Ti Kan | vorsprung durch technik! \\\ Internet: ti@altos.com Voice: 408-432-6200 ext 4266 \\\ UUCP: ...!{sun|sco|pyramid|amdahl|uunet}!altos!ti /// \\\ The opinions herein are not necessarily those of Altos. ////////\
