Short answer: the Adam Audio S2V for accuracy, the Klipsch The Sevens for bass. The S2V’s spinorama shows clean driver blending through an imperceptible crossover, with distortion 70dB down at 1kHz, though a shelving curve dips the low bass around 200-500Hz. The Sevens cost $2,399.99 less and reach about 40 Hz in-room with a solid, controlled thump, measured to F3 49Hz/F10 36Hz, but their horizontal radiation is narrower than the Klipsch The Nines.
Buy the Adam Audio S2V when sound quality outweighs the price for you, and the Klipsch The Sevens when the price outweighs sound quality instead.

The Two Speakers In Full
Adam Audio S2V: $3,399.98 per pair Amazon eBay
Pros: A 7.98 ideal-subwoofer score and relatively even listening-window response support a strong role as a subwoofer-assisted studio monitor. The review’s low-distortion findings add useful evidence beyond amplifier ratings, and onboard DSP permits tailored adjustment. The review measured distortion about 70dB below the signal at 1kHz. Measured bass extension of 52.7Hz (-3dB).
Cons: Measured -3dB extension is 52.7Hz, so the large cabinet does not automatically deliver the deepest bass here. The native balance rises toward the treble, with some lower-midrange unevenness. DSP can improve that balance, but an EQ-optimized result is not its unadjusted performance.

Klipsch The Sevens: $999.99 per pair Amazon eBay
Newer model: the Klipsch The Sevens II. It’s likely to perform similarly, though we can’t confirm that yet.
Pros: Erin reported 49Hz -3dB extension, with useful bass for ordinary music listening. HDMI, phono, USB, optical and Bluetooth connections make the system convenient for TV and music, while app controls and a subwoofer output provide adjustment options. Bass reaches about 36Hz at -10dB, delivering a controlled thump near 40Hz in-room without strain. Measured bass extension of 49Hz (-3dB).
Cons: The review found a recessed 2-4kHz region and upper-treble emphasis, producing a scooped balance that a simple treble reduction did not fully fix. Relatively narrow horizontal coverage limits consistency across seats.
