Short answer: the Genelec 8351B if sound quality matters most, the Klipsch The Sevens if price matters most. The Genelec 8351B ranks #4 of 113 powered bookshelf speakers, rated 4.8/5, at $9,900. The Klipsch The Sevens ranks #105, rated 3.7/5, at $849.99, $9,050.01 cheaper.
The case for the Klipsch The Sevens: Erin reported 49Hz -3dB extension, with useful bass for ordinary music listening. It keeps a wired aux input, which the Genelec 8351B lacks. The tradeoff: 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.
The Genelec 8351B is the better-sounding, deeper-bass choice. The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Its bass reaches about 33Hz before falling 3dB, against 49Hz for the Klipsch The Sevens. The catch: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material.

The Two Speakers In Full
Klipsch The Sevens: $849.99 per pair Amazon eBay
Newer model: the Klipsch The Sevens II, ranked higher, estimated 3.8/5.
Same family: the Klipsch The Fives (smaller bookshelf, rated 4.3/5) and the Klipsch The Nines (larger bookshelf, ranked higher, rated 4.2/5).
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.

Genelec 8351B: $9,900 per pair B&H Photo Video eBay
Older model: the Genelec 8351A (ranked lower, estimated 4.6/5).
Same family: the Genelec 8331A (smaller bookshelf, rated 4.8/5), the Genelec 8341A (smaller bookshelf, ranked lower, rated 4.8/5), the Genelec 8361A (larger bookshelf, ranked lower, rated 4.8/5) and the Genelec 8381A (floorstanding, estimated 4.9/5).
Pros: The vertical ASR measurement scores 7.75 with an ideal subwoofer and reaches 35.2Hz at -3dB. Coaxial midrange and treble help maintain consistent sound as the listening angle changes. Low measured distortion at ordinary listening levels and GLM calibration make it a strong precision-monitoring choice. Measured bass extension of 33Hz (-3dB).
Cons: Bass distortion increases at higher playback levels, so a subwoofer remains useful for demanding material. Upper-treble distortion in the test also cautions against assuming unlimited output. Calibration hardware adds to an already expensive system, and the quoted result is for the measured vertical orientation.
