Frequently Asked Questions
Can the CMX WSK-640H be installed in outdoor environments?
Yes. The WSK-640H is built with a rugged, UV-resistant ABS cabinet and a powder-coated rust-proof metal grille. It is engineered specifically for covered outdoor environments such as restaurant patios, perimeter walkways, building facades, and open-air transit corridors as well as indoor commercial spaces.
What is the benefit of the 8-Ohm bypass setting on the WSK-640H?
The 8-Ohm bypass setting bypasses the internal line-matching transformer, allowing direct connection to low-impedance commercial or residential stereo amplifiers. This delivers superior transient response and full dynamic range for high-fidelity foreground music playback.
How do I adjust the speaker power tap on a 100V or 70V commercial system?
A rotary power tap switch is located conveniently on the rear panel. Installers can easily switch between 40W, 20W, 10W, and 5W on 100V lines (or down to 2.5W on 70V lines) to balance volume levels across different architectural zones without taking down the speaker.
What mounting hardware is included with the CMX WSK-640H?
The speaker comes with a factory-supplied heavy-duty stainless steel U-bracket. The bracket supports both vertical and horizontal wall or ceiling mounting with full rotational tilt adjustment for precise sound targeting.
Which amplifiers are recommended to drive the CMX WSK-640H?
For 100V distributed lines, the WSK-640H seamlessly pairs with CMX commercial mixer and power amplifiers including the CMX PA-2120MX (2×120W), CMX PA-2240MX (2×240W), CMX DA-240 (240W), and CMX EA-500A (500W). Maintain a 20% safety margin when calculating total connected wattage.
