Short answer: the Genelec 8040B for better sound quality, the Adam Audio T8V for the lower price. The Genelec 8040B ranks #9 of 62 powered bookshelf speakers at $2350. The Adam Audio T8V ranks #28 at $349.99, $2000.01 cheaper.
What the Adam Audio T8V offers: Quite balanced and neutral, very close to the Yamaha HS8. Deeper bass than the HS8 Watch for: A crossover-region notch around 4.6kHz where tweeter and woofer interact, and a hole in the vertical response below the tweeter axis - keep the tweeter at or above ear height. Distortion is well controlled at 86dB SPL but gets messier at 96dB.
What the Genelec 8040B offers: Based on their smaller speaker’s performance against others, I’m ranking this accordingly. Watch for: Very expensive
Buy the Adam Audio T8V if the price matters more than sound quality. Buy the Genelec 8040B if sound quality matters more than the price.
