Thanks CarlosT, I'm just wondering how accurate that program might be!

 

[CarlosT]

It's pretty neat...you can't ave the files but I think it works OK. You'd have to compare it to some other program like WinISD or something...

LspCad is quite accurate, but not particularly cheap.

What about the Harris Tech BassBox 6 Pro? Would this be compatable to the LspCad?

I think the easiest is winspeakerz.
But u hv to pay 4 it.

My knowledge of BB6 pro is limited to dimly recalling some folks posting on the old Basslist of not being very pleased with it overall, but that was a lifetime ago in software years, so can't comment beyond being very pleased with Lspcad's accuracy.

I hv bassbox pro, winspeakerz, subwoofer design toolbox & ajbandpss.
There is very little difference in designing.
But i found winspeakerz to work easily. U can interact with it very easily. I am using others to just crosscheck.

Thanks guys for the info. I am trying to design a bandpass enclosure, for a 10" woofer, that would be suitable for hi-fi audio. I saw a fourth order band pass calculator on this site: http://www.colomar.com/Shavano/4thorder_info.html
Was wondering how it would compare to the other programs you guys had recommended?

Once again, Thanks for the Help!

...I am using others to just crosscheck.

So you've found the accuracy to be pretty much on par for all these programs?

Every program hv it's plus points & negative points.
AJ bandpass is not interactive.
Bassbox pro shows different matching.
But if results from bass box pro fed to winspeakerz, then they r ok.
Winspeakerz gives u 9 different graphs. u select what u like.
Bassbox pro & winspeakerz r auto as well as interactive so that we can design the box as required by us.
Then we can crosscheck with other softwares.
In Subwoofer design tool box u need more experience to design bandpass box.
But the results r almost same within 2~3%.

palesha, could you check out this link: http://www.colomar.com/Shavano/4thorder_info.html
and let me know if it compares to the other programs you mentioned.

Thanks,

I visited the website.
The software is a simple one.
S factor is with .1 diffrence. it is high.
The port frequency step is 5 mhz. It is too high.
If u want precise results than u hv to buy commercial version.

No lunch is free.
or else give me the speaker specs with DC resistance, Qts, Vas, Fo/Fs. & ur requirements, all at one time, i will give u the box designed along with graph.
