| Re: Extech 407730 SPL Meter
Looks like a very nice unit. Most meters and microphones loose accuracy at the low and high frequencies and require a calibration file. SPL meters usually conform fairly close to their C-weight characteristics down to about 30hz and then need a bit of correction.
If you were going to use your meter for subwoofer measurement where you weren't trying to test down to very, very low (i.e. 10Hz), I suspect your meter would be fine for home use by simply using the C-Weight cal file in REW......
