[QUOTE="Buck, post: 8795846, member: 591582"] I use winisd pro a lot. I’ve ran 1000+ woofers through winisd, so I know what to look for. I’ve seen a few programs not model well, but it all comes down to you knowing what you’re doing, from my experience. Like I have my own port length calculators in excel, amongst other things, that I all setup myself. If you ever do put box formulas onto your own spreadsheet, it can really help you understand some dynamics of boxes based on the equations you have to use. To a large extent, tuning is tuning. Most of the time the simple models you can get for free aren’t really that useful; it is useful to compare models against each other with different woofers to understand the woofer better. I just mean no matter what your model looks like, box space is box space and tuning is tuning, and any different woofers of the same cone size are only going to vary so much with what they need. Say tuning to 32 hz is typically going to give you a similar response across the board, because that’s a hard structure pressurizing at the frequency, regardless of woofer Fs or cabin gain. The woofer specs and cabin gain some, but the biggest factor in response with ported is your hard tuning, and the response will revolve largely around that. Some vehicles boost differently than others, but then again, there’s only so much variance between vehicle shapes and resonances that you’re going to run into. Too many factors can change sound, so you really have to develop a feel for it, if you want to be good or better than you are now when designing, or have an easier time. At certain point of knowledge, you may be able to see sound better in your mind; that’s what happened to me over time. [/QUOTE]
