Default Crossover Modelling Program

Greetings from Christchurch, New Zealand.... I have just bought an older version of David B. Weems book on " Great Sounding Stereo Speaker Manual"... I have to say that it is REALLY easy reading, technical, yet easy to understand, very much enjoyed. I bought it 2nd hand and 'as new' condition, even had an un-opened CD in the back pouch. I have a problem, as the CD is from 2000, my new computer is not able to support this program. Is there an updated version available for the 'Crossover Modelling Program' or can someone advise on another good 'Freeware' item... I am really enjoying my venture in tube amps and speakers... many thanks.... Keith Brinch

Default yep - PCD

I'll stick my neck out and say that the best freeware passive crossover modeling program is Jeff Bagby's Passive Crossover Designer, or "PCD" for short. I host it on my web site, where you can find other freeware for speaker design:
software

I have developed and have been beta testing an active crossover modeling program. Please post here or send me a message if you are interested in active crossover design.

You do know, you need correct models for the drivers and your baffle. None of the spreadsheet calculations are anywhere close because of that. I use Sound Easy. Not cheap, the stuff to measure everything is not cheap. Not quick. The results are close enough for a first prototype. You are not even going to get the right number of poles and zeros.

Hi Keith, Yes, I have a Weems book I bought new in the early '80's in Palmy North and have found it one of the most easily followed too.

Assuming your software cd is for older Windows then if Win2000 can you not use the compatability mode of your current Windows ?
(Assuming here you are using some version of Windows ?? and not mac or Linux.)
What about running in a Virtual environment if you have an old Win200 install disc..?
Or a dual boot using a Linux O/S and Wine to run the software..?
I would be happy to test some of these options if that would help.... pm me if you want to try that.

Cheers, Bob.
