Revel in-ceiling loudspeakers draw upon the same research, resources, and unique perspectives that put all our loudspeakers in a class by themselves. Each model offers a standard-setting low sonic coloration and freedom from distortion over a wide dynamic range. * Long-throw woofers with cast frames and rubber surrounds provide high output with low distortion. * 1-inch (25mm) angle-adjustable, metal-dome tweeter with an integrated waveguide provides optimized response both on and off axis. * High-order crossover network with premium-quality components delivers extraordinarily accurate timbre reproduction. * Boundary compensation switch (C783/C763) lets you adjust the speaker to maintain tonal accuracy when the speaker is placed near a wall. * Three-position tweeter level control (C783/C763/C583/C563) lets you adjust for optimum response in a variety of acoustical environments, or for using the speakers without grilles. WHAT'S IN THE BOX? * 8" Internal In Ceiling Speaker
