Martin Audio F215+ Full Range 2 x 15" + 1.4" Passive Enclosure
The Martin Audio 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. An aluminium demodulating ring improves the midrange performance at high levels and increased excursion is available via a triple roll surround and deep motor structure.
The F215+ can be used with or without a controller. Use of the M3+ or DX1.5 will enhance the low frequency performance of the system and provide high quality limiters to protect the F215+ from being overdriven.
