The first M12 was launched back in 2008, since then the amplifier has always made a statement that set itself apart from the other high end competition amplifiers.
Backing it up were scores of 175 dB + at the 2009 World Finals with a single M12! The second generation of the M12 dawned in 2011 and completely redesigned for a specific purpose;
the ultimate power output without loss of efficiency and the increase of THD.

M12R builds on the same cornerstones as its predecessor, but the limited production run makes it even more sought after, only 30 are to be made. Any of our amplifiers bearing the R badge have ushered in a revolution of change! Never dwelling on past sucess, B2 audio continues with the same passion to raise the bar effortless.

The M12R is a result of such, even surpassing the power of the M1u, (another amp knowing to have been the choice of the world champions), the bridgeable dual mono design can control multiple of your woofers with an authority of  more than 14.000 watts!* Clear to say, only proven and tested parts from the worlds leading manufacturers are used in this amplifier.

No stock is kept of old parts, only freshly picked from the same batch , hand matched and tolerance tested prior to finding its way into the M12R. Power is nothing without control, while juice is needed to maintain power. A properly dimensioned battery system will keep your M12R running healty as the current draw can easily go beyond 1100 ampere.

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over) dimensioned. Failure to upgrading will constrain the power output & lower the efficiency which can cause damage to the amplifier & void the warranty, this also includes ohm loads below of what is written in the manual. Do take your time and read the manual thoroughly before installing!
