IQ CM8S In-Ceiling Speakers

Designed like no other, the IQ speakers deliver in quantity and quality. Aluminum electroplated carbon fiber cones with an overhung butyl surround maximize the piston area to produce louder bass effects. Aluminum electroplating the carbon fiber adds strength, life, faster, and more accurate overall performance.

Another hot feature is the dual rotating neodymium tweeters, which give you line-action high-frequency response and broader sound dispersion, eliminating diluted images and hot spots. IQ’s sophisticated and elaborate crossover networks use neither 100 nor 200 but 250-volt mylar caps, delivering performance well above the needed linear response.

These speakers, covered with anti-rust 16-gauge powder-coated aluminum grilled, are ideal for high-humidity areas such as bathrooms, indoor pools, and atriums. Each IQ speaker has three-way switches that can correct human ear imperfections and iron out flaws in your system.
