## About

A two-way open baffle with everything inside it: streamer, DSP and 370 W of Class D per speaker, split between separate amplifiers for the two 15-inch woofers and the brass horn above them. There is no cabinet, so nothing is compressing air behind the cones and nothing is colouring the sound with its own resonances — the trade is a 56 cm-wide oak baffle that needs room to breathe. Neither speaker is the master: the two are electrically identical, linked by I²S over HDMI at 24-bit/192 kHz, and the pair works out between them which one is playing the left channel.
