Short answer: the M-Audio BX8 D3. It ranks #50 of 68 powered bookshelf speakers by sound quality, rated 4.0/5, at $129; the Presonus Eris Studio 8 ranks #59, rated 3.9/5, and costs $209.99, which makes this an easy call rather than a real tradeoff.
What the M-Audio BX8 D3 does well: Measured -3dB extension of 48.3Hz provides useful musical bass, with a 6.66 ideal-subwoofer score. Watch for: A 3.9dB response span from 300Hz to 5kHz and downward tonal tilt suggest a darker, less even presentation than the leaders.
What the Presonus Eris Studio 8 does well: 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 M-Audio BX8 D3. It is rated higher for sound quality than the Presonus Eris Studio 8 and costs less, so the other one has nothing left to offer.

M-Audio BX8 D3: $258 per pair B&H Photo Video eBay
Pros: Measured -3dB extension of 48.3Hz provides useful musical bass, with a 6.66 ideal-subwoofer score. The large woofer and analog connections suit a straightforward studio setup without requiring a streaming ecosystem.
Cons: A 3.9dB response span from 300Hz to 5kHz and downward tonal tilt suggest a darker, less even presentation than the leaders. The 8-inch driver and amplifier rating are not proof of deeper or cleaner bass than smaller competitors. Room controls cannot fully correct frequency-dependent directivity.

Presonus Eris Studio 8: $419.98 per pair Amazon eBay
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.
