Our first dipole model, the D1 looks like a traditional box, but is an open baffle. Front drivers are a 11" x 9" planar magnetic horn mid-tweeter 650 Hz-14 KHz, a 1" horn super-tweeter 14 KHz-28 KHz, a 12" mid-woofer 60 Hz-650 Hz and a 12" servo amplified subwoofer 14 Hz-60 Hz . On the rear, a 10" x 7" planar magnetic mid-tweeter fires directly behind the front horn in dipole fashion 650 Hz-18 KHz.
The system is fully active. An external box contains a dual channel Hypex and Rythmik servo amplifiers, with controls for bass levels and variable low pass crossover to best match the room.
