MartinLogan - Motion XT Series CI, Retro-Fit Backbox Enclosure for XTC8-HT - Black/Silver

One of the benefits of in-ceiling speakers is how easily they disappear into a room. Unfortunately, the sound coming from the back of the speaker doesn’t disappear and can distract those in the rooms above the speakers. MartinLogan offers back boxes, or enclosures, for Motion CI and Motion XT CI In-ceiling speakers. For these situations where sound control is desired, these retrofittable back boxes are the perfect solution. They offer 20dB of noise reduction into adjacent areas and offer the perfect solution to achieve consistent performance where ceiling cavity sizes may vary throughout an installation. Please note that the volume of air in the retrofit enclosure is smaller than that of your ceiling, and bass extension will be reduced. If sound control is not necessary for your unique installation, we recommend not using the back box so the speaker can take advantage of the larger airspace in your ceiling cavity.

Installing quality in-ceiling speakers doesn't have to be difficult! This pair of Yamaha NS-IC400WH 4 In. 90 Watt Max In-Ceiling Speakers are easy to install thanks to the large mounting clamp with nonslip tread for sure grip. Plus they have paintable magnetic grilles, making them ideal for various custom installation requirements, including in-wall. Each speaker also features Yamaha's original double-layer 4 in. cone that creates natural sound tonality, a ridge-shape aluminum center cap with stair-like speaker surround that helps smooth frequency response from low to high, a sealed back cover to protect speaker and crossover from dust and moisture, and a grain-finished acoustic baffle with spiral pattern for natural sound dispersion.

The Ci5120QLM-THX features four specially designed 120mm (4.75 in.) bass drivers that offer long throw capabilities and very low distortion, delivering deep, clean bass even from a compact driver
