## About

4.4 kg and 79 mm deep, with its cabinet machined from solid aluminium and the bass handed off entirely to separate boundary woofers — which is how something this small reaches 114 dB. The trick it borrows from the Model D is dipole radiation: an angled reflector throws the tweeter's rear output sideways instead of absorbing it, widening the sound field while cancelling the first sidewall reflection. The maker files it as bookshelf, on-wall, in-ceiling or stand-mounted, all four.
