How to use

Mount the speaker in the chosen ceiling or on the wall following standard electrical safety practices and local installation codes. Connect the left and right stereo wires to the corresponding amplifier or audio source outputs, observing polarity to preserve channel separation and phase. Set amplifier power limits according to the speaker's rated power to avoid overdriving. After installation, perform an audio check across the listening area and make small adjustments to amplifier volume and tone controls to achieve balanced background sound.

Recommendations

For reliable long-term operation, use with low-power amplifiers or dedicated multiroom audio controllers designed for 4 Ω loads. Position speakers evenly across the space for uniform coverage, and avoid placing high-SPL sources nearby. Periodically inspect mounting and wiring connections and keep the speaker free of dust accumulation to maintain consistent audio performance.
