Aperion Audio Novus 5.0.2 Speaker System Review Test Bench

Test Bench

I conducted several in-room measurements using the Parts Express Omnimic measuring software and microphone. Though the results from this $300 package are not as precise as might be obtained from more expensive test gear, it can provide a usefully accurate in-room response of a speaker at the chosen listening seat when used carefully. The results shown here are for my room. All of them were taken at the single, seated ear position, not an average of several positions. (Previous experience has shown that an average of several readings in my room, taken across a span of about 2-3 feet, differs little from the single position apart from smoothing out small ripples.) For all curves, red is the left speaker, blue is the right.—TJN
