Sonus faber Lumina Surround Speaker System Review Test Bench

Test Bench

I conducted several in-room measurements using the Parts Express Omnimic measuring software and microphone, a $300 package that offers a usefully accurate response of a speaker at the main listening seat. The results shown here are for my room. All were taken at the single, seated, ear-level position. (Experience in my room has shown that an average of several readings, taken across a span of about 2 feet, differs little from the single position measurement apart from smoothing out small ripples.) The graphs here are 1/6th octave smoothed.—TJN
