outdoor test question

[screamersusa]

If the only place I can test outdoors is a large EMPTY parking lot. Are there any suggestions for adjusting readings with an oscillator and a rat shack db meter. My laptop died so no true rta.
Should the cabinet be on the ground or elevated?
For a TH or folded sub, Mouth down or up (upside down)?

I'm going to test at 100w 10m, then with a 35hz cutoff filter in line.
I also want to test max spl to see what the box will do in combat.

Thanks.

You should elevate the speaker if you want to avoid early floor reflection.

You could keep it on the floor if you want to see what some floor interaction will do to the frequency response...

Max SPL tests outdoors are a bit misleading if your speaker will play indoors. The reading will be MUCH higher indoors.
