Short answer: the Genelec 8351B for better sound quality, the Adam Audio T7V for the lower price. The Genelec 8351B ranks #6 of 66 powered bookshelf speakers at $9150. The Adam Audio T7V ranks #55 at $289.99, $8860.01 cheaper.
What the Adam Audio T7V offers: Spinorama’s digitized Audioholics data shows a fairly controlled 2.4dB frequency-deviation band from 300Hz to 5kHz, with only 0.7dB reference-band variation. The response above 200Hz is broadly balanced and the supplied correction filters require relatively modest adjustments, consistent with a monitor that responds well to EQ. Watch for: The available Spinorama record is a low-quality scanned graph truncated below 200Hz, so no preference score or trustworthy bass-extension score can be calculated. Vertical dispersion is narrow and listening height matters; the incomplete data does not justify the previous 4.3 rating, so an uncertainty adjustment is applied.
What the Genelec 8351B offers: CEA2034 spinorama shows exceptionally flat response both on- and off-axis. Predicted in-room response is “as good as it gets” - should sound very neutral in nearly any room. Horizontal beamwidth of about ±50 degrees is described by the reviewer as exceptionally smooth, a model example of well-executed directivity control. Vertical directivity is nearly as good as horizontal, a benefit of its coaxial driver design that’s rare among non-coaxial monitors. Distortion at 86dB SPL/1m is remarkably low - the reviewer says it’s “better than many headphones.” Watch for: Deep bass distortion rises substantially at higher output (96dB SPL/1m) - the reviewer notes “deep bass suffers” below about 100Hz. A distortion spike also appears near 8-10kHz at that same higher output level. Cumulative spectral decay (waterfall) measurements show resonances around 1-2kHz. Very expensive.
Buy the Adam Audio T7V if the price matters more than sound quality. Buy the Genelec 8351B if sound quality matters more than the price.
If sound quality matters at all to you, skip the Adam Audio T7V. It ranks near the bottom of the 66 powered bookshelf speakers, so look higher up the list instead.
