Short answer: the Adam Audio S2V for better sound quality, the Klipsch The Sevens for the lower price. The Adam Audio S2V ranks #13 of 67 powered bookshelf speakers at $3500. The Klipsch The Sevens ranks #64 at $999.99, $2500.01 cheaper.
The case for the Adam Audio S2V: CEA2034 spinorama shows excellent driver blending through an imperceptible crossover between the 7” woofer and AMT tweeter, with distortion measured 70dB down at 1kHz. The tradeoff: An intentional shelving curve creates a dip in the low bass response, roughly 200-500Hz.
What the Klipsch The Sevens gets right: Genuinely good bass - reaches about 40 Hz in-room with a solid, controlled thump and no real strain, backed by measured extension to F3 49Hz/F10 36Hz. The catch: Notably narrower horizontal radiation than its stablemate, 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.
If sound quality matters at all to you, skip the Klipsch The Sevens. It ranks near the bottom of the 67 powered bookshelf speakers, so look higher up the list instead.

Adam Audio S2V: $3500 B&H Photo Video eBay
Pros: A 7.22 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.
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 Amazon eBay
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.
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.
