Bookshelf Speaker Reviews

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 of them were taken at the single, seated ear position about 10 feet from the speakers, not an average of several positions. (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.) All curves here are 1/6th octave smoothed.

The graphs here are for the L/R Elac UBR62s. Fig.1 is for the left channel only, without subwoofers. Red is without Audyssey, blue is with Audyssey used only below 300Hz. The latter is obvious from the graph in which the two curves overlap so precisely above that frequency that they can't be seen separately. Audyssey here corrected for room-related peaks between 100Hz and 200Hz and slightly but usefully extended the Elac's response between 50 and 60Hz.—TJN
