Edifier R2850DB vs Adam Audio S2V

Last updated: August 18, 2026

Short answer: the Edifier R2850DB. It ranks #32 of 40 powered bookshelf speakers by sound quality at $424.99; the Adam Audio S2V ranks #37 and costs $3500, so there is not much of a tradeoff to weigh.

On the Edifier R2850DB side: 3 way speaker. Set against that: Quite large and heavy.

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.

Buy the Edifier R2850DB. It ranks higher for sound quality than the Adam Audio S2V and costs less, so there is no real case for the other one.

If sound quality matters at all to you, skip both of these and look higher up the 40 powered bookshelf speakers instead.

Adam Audio S2V: $3500 Bhphotovideo

Adam Audio S2V ranking card

Pros: 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 350W amplifier was the first the reviewer tested that didn’t run out of power on demand, delivering over 120dB SPL per pair.

Cons: An intentional shelving curve creates a dip in the low bass response, roughly 200-500Hz. The rotary-encoder control interface is non-intuitive, and the companion PC app requires serial-number registration with settings that only take effect after a manual “write” step that takes 5-10 seconds and produces audible ticks and pops. Expensive at $3,500 per pair.
