DESC: Who said your whole-house audio system has to sound like the tinny, unfocused music you get in an elevator? For big bass and smooth, well-dispersed highs, try these Niles High Defition ceiling-mount speakers. The CM8HD speaker from Niles Audio was designed to bring you detailed, high-fidelity sound, while leaving your walls and floors free for your furnishings. A long-throw, low-distortion 8" TCC (talc-, carbon- and ceramic-filled) woofer delivers full bass. A 1" fluid-cooled Teteron® trilaminate tweeter sends out clean, accurate highs. Because the tweeter is housed in a custom pivoting enclosure, you can angle your sound up to 20° for greater impact.
