Just wondering if any of you good people out there have used the program and then measured different results than what was projected? As you surely know, certain enclosures can involve quite a bit of time and money, and since it is a free program, I wonder sometimes just how much I should trust it.
There is no reason it should not be accurate. I think it’s more a features issue than an accuracy issue. You are probably asking this in the wrong place, the AVS Forum DIY section would probably be better. http://www.avsforum.com/avs-vb/forumdisplay.php?f=155
I don’t do much with box speakers anymore and virtually never with ported. Just don’t have a use for them! A simple pocket calculator is all you need for sealed systems or open baffle systems. The tools you do need are LspCAD and some sort of measurement system. I use Arta with an Earthworks M-30 microphone but a cheaper option would be this… http://www.parts-express.com/pe/showdetl.cfm?Partnumber=390-790 It uses a modified Panasonic mic element that is pretty close in quality to my M-30. I haven’t tried this system but I’m familiar with the guy that designed it and it should be very good.
You’ll have to check with the DIY’ers on the AVS Forum about box modeling software. I know Bass Box Pro is a popular one. I’ve been doing almost exclusively open baffle for 16 ~ 17 years and have little or no interest in conventional box speakers. They do still have their applications, not sure that’s true of ported systems but I suppose that’s a matter of taste.
