I have done a search regarding the pros and cons of using the analog vers digital RS spl meters. I currently have the analog version but the digital one is on sale at the moment, and I have read that one of the features of the digital is average reading which some users are using to calibrate their subs. Does this feature make calibrating the subs easier, as currently I have two subs and a BFD 1100 eq, would this make the calibration easier when using a test disc with test tones. i.e. for a 5 second test would the result be more in line with real life results, or due to fact the this meter dosen't resolve less than 1db mean the the results are a waste of time?
