Thanks Zero. searching wpr only found the projects shortcuts, but an advanced search found it lurking at C:\users\app data\local\virtual store\program files\linearteam\winisd pro\projects.

I have copied projects to the desktop, but wonder if I need to try a reinstall. WinISD seems to be working. I need to go online and find out how to use things like xmax, maximum spl and such.

So, how do I calculate maximum spl of a SWR 1041D which isn't my driver (1040D) with just one 4 ohm voice coil hooked up to the Crown DC300A which has 150wpc @8 ohms (I don't know the wpc @ 4 ohms)?

Good news, it worked

For the future, if you right clicked on, one or more shortcuts, it should bring up Properties. On there a Tab called Find Target, which should locate them.

Using the WS should have found Projects in there before ? I should have mentioned using AS ! Anyway i'm glad you've found them at last, & not lost them forever. I thought you would find them with a search

It won't do any harm to Reinstall, but make SURE All your .wpr's are Definately saved in that Desktop Folder for now FIRST. Plus keeping backups in there would be a nice safeguard, just in case something goes amiss again ! I've never had such issues though in All the years i've been using it. So it probably was a one off ? Uninstall before you Reinstall.

Sure, but the more you experiment with WinISD the more you'll learn. Try different box sizes & tunings & power etc & you'll see how things change. Sometimes for better/worse, depending on what you're trying to achieve.

It depends on the size of the box & tuning frequency. It's rated @ 305WPC @ 4Ohms http://www.crownaudio.com/media/pdf/legacy/dc300a2.pdf

Here's the data for various drivers, including the SWR 1041D http://vault.alpine-usa.com/products..._SWR-1241D.PDF

I found both those via https://www.startpage.com

I notice that quite a few important parameters are missing from their TS specs ? And from your WinISD screenie. I suppose you couldn't find them due to Alpines not including them ?

I've worked them out for you.

BL = 14.98 NA

Mmd = 138.84 Grams

BL is the Really important one missing, & without it you won't be able to design anything meaningful. Mmd i've just shown for completeness. Do NOT input it yourself, allow WinISD to Auto calculate it, due to the reason below.

Please pay CLOSE attention to the advice i gave in my Tutorial i linked to earlier. ONLY Input the parameters in the EXACT way i described. Otherwise you will end up with incorrect data in WinISD = Not good !

Also you didn't Input any Power rating for the driver ?

Ok, after many hours of trial and lots of error, here is what I have. The Alpine is low passed at 80hz, but mayby it should be lower?

Thanks for the help Zero, I did delete and reinstall WinISD Pro and did not lose my projects. The program still has major issues running on Vista, with error reports popping up contantly. Strange little program.

80Hz is usually fine. You need to raise the Xover f on the Altec to match the Alpine. Same f & dB Octave

For some reason i can't view your screenies on photobucket ? So in future could you upload them directly to here

Wierd ! I thought it was Vista compatable.

Why don't you install WinISD v0.7.0.809 which is what i've been using for some time now. Their www forum is offline due to Lots of Spam, but i've managed to find the download link for you

It auto-closes if you try to input distance <1m, but some of the new features are rather nice - thanks for the link!!

@ chris661

Pleasure !

I've never tried it @ less than 1M, or need to. But your observation might be useful to others

Remember it is Beta

WinISD v0.7.0.809 wound't install, I am down to my last 11Gigs of harddrive. What to do now? Should I get an external magnetic drive or a digital flash one?

Just got the wires to hook up the Crown and Soundcraftsmen and freaked out when one of the subs channels was dead. Ripped out all of the wiring, wired and rewired until everything was in knots and finally hooked up the Sony Discman to the Radio Shack switching thingy to the EQ, to the pre-amp, to the Crown, and finally the Altecs, and all is good. It must be the wiring inside the sub box as both subs work, just not at the same time.

Amazing how the Crown sounds compared to the Radio Shack Sherwood amp. Tomorrow, hopefully I will get everything sorted out and be able to run the Alpines full range and see what the sensitivity difference between the two is.
Makes me want to re-cone the A7-500s. J

What error messages did you get ?

It's still a lot, depending on what you store etc ! And WinISD is less than 2.5Mb

External will give a a lot more space

I have a feeling something/s "might" be wrong with your comp. Are you running in Admin mode, or LUA for eg ? First off, try this on BOTH versions. Right click on one at a time ONLY, & follow my screenies for each one in Turn & see if they run OK.

Hope you get the subs sorted !

Help!!! How do I hook up all this crap? Anybody have a Soundcraftsmen SP4000 Manuel, or a 4001/4002? This preamp looks 2 inches too short for the internet pictures. I can get the sound source to flow un-amped to the secondary EQ to the amp for the Altec's or through the volume control to the EQ to the Crown to the Subs, but not both at the same time.
It looks like it should be possible, but I'm not smart enough... I guess I could Y the imput source to the Soundcraftsmen preamp and the crown amp?

Arg.
