Improving a benchmark proved to hard, the first Duo was at its best for several years & is still considered unique.
But we are not known to dwell, therefore we started working on the successor. The B2 audio Duo MKII.
With a brand new pcb we opted for a wider heatsink to allow for better heat dissipation.
2 oz copper traces on a dual sided pcb along with hand picked and matched components from the finest suppliers (Sanken), ensures the pure audio reproduction. The Dual 0 Gauge power terminals ensures better efficiency and optimizes dynamics which are cornerstones in any SQ installation. However they do also serve a purpose as 1 ohm operation sets demands to stock electrical systems.
For those in need of something more than the ordinary, the Duo now features individual gain for each channel and also potentiometers with corresponding frequencies for each click.
That way you will be able to set your crossover at the exact setting required for a true audiophile experience, also described as Sweet Like Danish.
Even if a full range amplifier, the Duo will truly show its strenght in a subwoofer configuration. With 3000 class A/B watts into 2 ohm bridge or 2ch stereo (2 x 1500 watts), it will surpass many larger class D amplifiers in SQ, dynamics and headroom.

*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!
