Can we Poll the Peers here, and get some dialogue on experiences with the WinISD freeware?
1) Does WinISD produce an accurate representation of woofer response?
2) What T-S parameters are the most critical and are the plots most affected by (besides Box Volume)?
3) WinISD does not seem as sensitive as I would have suspected to port area. True, or am I not observing the effect correctly?
The attached plot of the 128H (green) and LE14A (white) transducers in identical 93.8 liter vented enclosures yields probably indistinguishable responses. Is this result reasonable? Is it correct?
