The B-112P in our 'OG' aesthetic perfectly complements our A3 speaker by adding significant bass capability. 
 
It's a 75 litre (internal) box containing a high performance hifi woofer / subwoofer driver. This box / driver combo will reach down to 20Hz in room.
 
The 'P' is the most basic version of our B-112 as it contains no crossover. The intention is for it to be matched to an external DSP crossover and amp.
