I have for sale my Bryston 10B sub active crossover. This is the version that has selectable crossover frequencies from 40 - 500 hz. It also has adjustable high pass gain and three different crossover slopes (6, 12 and 18 db/octave). The inputs and outputs are all unbalanced RCA and not XLR. The unit is in perfect functioning condition and cosmetically is scratch free on the front. The top is scratched as I think this one was once used in a professional rack. I can ship anywhere in the world and its a 120V version. I can send pictures on request. It is the current model but older cosmetics (also doesn't have the mute switches).
