Brand: Genelec

#5 Genelec 8330A: $2,250/pair Sweetwater

Pros: Sits between the compact 8320A and the larger 8331A in Genelec’s SAM lineup, with a die cast aluminum Minimum Diffraction Enclosure and Directivity Control Waveguide that deliver a measured 55.7Hz extension point, well beyond the 8320A’s smaller cabinet. The bass alignment is well damped at a measured Q of 0.379, so the low end rolls off cleanly rather than peaking near the tuning frequency.

Cons: On axis deviation measures 0.324dB average, rougher than several similarly priced monitors in this catalog, and listening window smoothness sits at a moderate 0.38. GLM room calibration requires the separate 9320A SAM Reference Controller or GLM Calibration Kit, an extra cost on top of the speaker price. At $1,125 each it costs roughly double the smaller 8320A for a moderate step up in bass extension and output.

How it compares: Just above it: Kali Audio SM-5 - $1150 more. Just below it: Genelec 8020D - $1150 cheaper.
