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 #51 of 68 powered bookshelf speakers, rated 4.0/5, at $998. The Presonus Eris Studio 8 ranks #59, rated 3.9/5, at $419.98, $578.02 cheaper.
Why pick the Focal Alpha 65 EVO: ASR measured 42.5Hz -3dB extension, providing useful low-end reach for music. 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: An 8-inch active monitor with XLR, TRS and RCA inputs and room-adjustment controls, providing flexible analog integration. 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.

The Two Speakers In Full
Focal Alpha 65 EVO: $998 per pair Amazon eBay
Pros: ASR measured 42.5Hz -3dB extension, providing useful low-end reach for music. Analog input options and tonal controls make it straightforward to integrate into a studio, with a 6.59 ideal-subwoofer score indicating respectable but not leading tonality. Measured bass extension of 45Hz (-3dB).
Cons: The measured 2.7dB response span from 300Hz to 5kHz and listening-window variation do not support a claim of reference-level neutrality. Placement and external correction may help. An anomalous distortion result from an individual sample should not be treated as a proven defect in every unit.

Pros: An 8-inch active monitor with XLR, TRS and RCA inputs and room-adjustment controls, providing flexible analog integration. Its cabinet and connection options suit a conventional studio setup.
Cons: The large cabinet requires substantial desk or stand space. Analog room-adjustment controls offer less flexibility than automatic calibration or parametric correction.
