## About

A two-way transmission-line stand-mount from Kerr Acoustic — a 180 mm wood-fibre mid-bass and a 60 mm True Ribbon tweeter in a Baltic-birch cabinet, revised to Mk.3 for a cleaner midrange. The larger driver and ribbon reach deeper than the K400, a hand-built British monitor for a medium room.
