Short answer: the Genelec 8330A for better sound quality, the Focal Alpha 50 EVO for the lower price. The Genelec 8330A ranks #5 of 64 powered bookshelf speakers at $2250. The Focal Alpha 50 EVO ranks #34 at $320.71, $1929.29 cheaper.
What the Focal Alpha 50 EVO offers: The available response trace suggests reasonably smooth on-axis and listening-window behavior, with Spinorama narrow-band-deviation values of 0.448 and 0.366 respectively. With a subwoofer its calculated preference score is 5.05, and the rear shelving controls provide some useful room and placement adjustment. Watch for: The only Spinorama data is a low-quality graph digitization rather than a Klippel measurement, so the extreme calculated bass and sound-power results should not be taken literally. That limited dataset produces a very low 0.40 full-range preference score, weak predicted in-room smoothness, and unusually inconsistent directivity. Independent high-quality measurements are still needed.
What the Genelec 8330A offers: 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. Watch for: 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.
Buy the Focal Alpha 50 EVO if the price matters more than sound quality. Buy the Genelec 8330A if sound quality matters more than the price.
