The QM 115 floor monitor features low profile cabinet design employing COAXIAL 15-inch LF woofer, concentric mounted HF driver with 3-inch titanium diaphram and 2-inch exit. The use of coaxial speaker is quite close to one point source and offers 70° conical dispersion which excels for monitoring applications Vs conventional floor monitors employing individual woofer and separate HF horn driver. The result is monitor with an excellent vocal presence, clarity and provides flat response without coloration as well as superior anti feedback resistance. The built in full range passive crossover, also offers bi amped operation via switch on the input panel. The QM 115 is capable of up to 133dB SPL allowing it to be used in concert applications where instrument stage volumes can sometimes overwhelm monitor mixes.
