Short answer: the Focal Alpha 65 EVO for better sound quality, the PreSonus Eris Studio 8 for the lower price. The Focal Alpha 65 EVO ranks #81 of 119 powered bookshelf speakers, rated 4.0/5, at $858. The PreSonus Eris Studio 8 ranks #99, rated 3.9/5, at $419.98, $438.02 cheaper.
Why pick the Focal Alpha 65 EVO: Studio monitors with useful bass for music, tone controls, and XLR, TRS and RCA inputs for easy studio setup. The catch: The measured 2.7dB response span from 300Hz to 5kHz and listening-window variation do not support a claim of reference-level neutrality.
The case for the PreSonus Eris Studio 8: A budget 8 inch studio monitor with XLR, TRS and RCA inputs and room adjustment controls for a conventional studio desk. The catch: The large cabinet requires substantial desk or stand space.
Buy the Focal Alpha 65 EVO if sound quality is the priority over the price, or the PreSonus Eris Studio 8 if the price is the priority over sound quality.
