MSRP $450, SAVE $170! Revel in-wall loudspeakers provide unparalleled value and are known for their standard-setting low sonic coloration and their freedom from distortion over an extraordinarily 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 (W893/W873/W783/W763) lets you adjust the speaker to maintain tonal accuracy when the speaker is placed near an additional wall or the ceiling. Three-position tweeter level control lets you adjust for optimum response in a variety of acoustical environments, or for using the speakers without grilles.
