The Ref FOUR from B2 Audio proves that B2 Audio is also extremely experienced in the SQ sound range. They prove with this high end 4 channel Class AB power amplifier their ability in the high end range and offer at the same time an optimal power amplifier to fire the reference series speakers REF15TW tweeter, REF3MR midrange and REF8 woofer.

The reference project has taken almost 2 years to arrive at a working design that meets our expectations.

Reputable component manufacturers such as Mcap, Nichicon, Burr Brown and IR were used to meet the stringent component level specifications required for this project.
