Two 7-inch bass drivers ruled out a two-way layout: their radiating area forbids a crossover around 2 to 3 kHz, and a 2.5-way configuration would have tilted the radiation axis downwards. EPOS therefore chose a three-way with a dedicated 130 mm midrange, crossed at 330 Hz then at 2700 Hz by modified LKR filters of the 2nd and 4th order. The column measures 1050 x 250 x 360 mm and weighs 35 kg.
The 8 cm diameter port opens under the plinth, which allows a length sufficient to tune the cabinet to 30 Hz. Pressure-equalising holes placed halfway along suppress the tube resonance and lower the parasitic output by about 10 dB compared with a conventional port. Response reaches below 30 Hz and up to 25 kHz in room, for a sensitivity of 86 dB and an average impedance above 6 ohms, at minimum 3.9 ohms at 16 kHz.
