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.

Klipsch The Nines: $999.99 per pair Crutchfield eBay
Pros: The 1.7dB response span from 300Hz to 5kHz supports even mids, and measured -3dB extension is 42.5Hz. Extensive consumer connections and app adjustment make it convenient for TV and music, while the horn provides a focused listening presentation. Erin called it his favorite Klipsch speaker. Measured bass extension of 42.5Hz (-3dB), with a measured sensitivity of 82.5dB.
Cons: The 6.90 ideal-subwoofer score reflects limitations beyond the narrow midband span. Horizontal coverage is relatively focused, so placement matters for multiple seats. The reviewer preferred reduced treble, and bass limiting at higher playback levels means the large woofer is not a guarantee of unlimited output. The app’s flat setting leaves treble elevated; Erin preferred a -2dB tweeter trim.
