Anyone know anything about this SPL meter? you can get a "kit" on amazon with the SPL meter and a laser aligner/level in a case for about half price. Would this meter be a step up from the RS meter? Will it be more accurate at low freq than the RS meter?
without a calibration file you will not get results that you can use properly, A calibration file can be made but you would need to know the 8810s exact specifications and you would have to make one.
Ideally the Galaxy CM140 SPL meter is the best all around meter to use with REW you can also use a ECM8000 microphone for more accurate readings but you still will need an SPL meter of some sort to get the levels set properly.
