During this time, we've continually refined our products to balance power, sound clarity and long-lasting performance. The AC6CD six-inch speakers easily install into your ceiling to combine out-of-the-way convenience with the audio needs of your home or business. Used in places where stereo sound is not required or impossible to present, such as hallways or bathrooms, these unique speakers combine R L stereo using dual tweeters and dual voice coil woofers offering a frequency response range of 50 Hz to 20 kHz. The speakers are designed to be moisture-resistant, with the woofers constructed of polypropylene and surrounded with Butyl rubber for durability.
