8ohm is a little different but should be fine.

I've decided that I will only be doing burst measurements from now on at DB. I've found that all of the other measurements are unnecessary and simply window dressing!:D

I can still mess with a td15m but I can tell you it won't fare well in a sine sweep compression test. That's not really a good metric for mid woofers anyway. I could measure distortion at say 20v and...

Man there is stuff piling up around here! Go ahead and send it. $15 will come I'm sure...A check would be fine. Its going to be a few months before it gets sent back so no rush really.

GH is a measured 122dB at 20Hz at 2m outdoors. Winisd defaults to 1m. Change it to 2m for comparison. Long story short either add 6dB full bandwidth for the GH or subtract 6dB for the vented.

Dcx2496 is -1 dB at 9Hz and -3dB at 5Hz. Not enough to matter for any sort of alignment other than sealed/IB.

Nope. Somewhere from 2:1 to 1.5:1.
CEA-2010 burst for the SW152 at 20Hz is 101.5dB, LMS is 108. Add 6dB for a second SW152 and it is 107.5. Close enough. Also worth noting is that the SW152 is in...
