F215 is a two-way passive, trapezoidal enclosure with dual 15" (380mm)/3" (75mm) voice coil low frequency drivers and a 1.4" (35mm) exit titanium diaphragm compression driver, mounted on a proprietary, rotatable, 80° X 50° Constant directivity horn.

Below 250Hz, both LF drivers operate together to produce low frequencies, whilst above 250Hz, only the upper LF driver is used to reproduce the midrange up to the crossover point. This technique avoids the uneven response which would occur if both drivers were allowed to operate together over the midband.

Each of the two new LF drivers features a tough, water resistant cone and a lightweight, high BL, neodymium motor system with inside/outside coil windings for improved heat transfer.
