About the Apex 40

The Monitor Audio Apex A40 is a versatile centre or surround channel speaker designed for vertical or horizontal use, freestanding or wall mounted. It combines advanced Monitor Audio technologies in a stylish, compact, and rigid die-cast alloy cabinet. Equipped with twin 140mm (5.5") C-CAM mid/bass drivers featuring Rigid Surface Technology (RST) and a 25mm (1") C-CAM Gold Dome tweeter, the A40 delivers a frequency response from 50 Hz to 35 kHz with a sensitivity of 90 dB and nominal impedance of 8 ohms. The speaker offers a maximum SPL of 116.8 dBA and is recommended for amplifiers between 50 and 200 watts RMS. Bass reflex alignment is achieved through twin front-mounted Dual HiVe II ports, providing smoother airflow and tighter bass response. The crossover frequencies are set at 600 Hz and 3.0 kHz. The cabinet's rigid die-cast alloy construction and single bolt driver fixings reduce distortion and box coloration, especially when wall mounted. The included bracket allows forward/backward adjustment and a 22.5º tilt for optimal setup. Dimensions are 610 x 140 x 100 mm (24 x 5.5 x 3.94 inches), and each unit weighs approximately 6.85 kg (15.1 lbs). The Apex A40 is finished in high gloss metallic black or pearl white and is praised for its build quality, aesthetics, and powerful, detailed sound uncommon in satellite speakers.
