So plugged my drivers in WinISD pro and playing around I've found that a 10ft^3 enclosure tuned to 28hz gives me a mostly flat response with a gain of 5db at 28hz and down 5db at 25hz. I'm wondering how accurate this program actually is, do these numbers sound reasonable? I'm running with a 1200 watt saz1200d so I need a very efficient enclosure and I want it to get lowww. My other question would be what do you guys use to measure cabin gain? I know about REW, wondering if theres anything better out there?
I want to measure my cabin response because I need to be able to factor in my peaks and nulls in my car to get a flat response between 40-80hz while maintaining a nice gain in the lows.
