Description
The CS-8R is an 8 inch two-way in-ceiling speaker engineered to reproduce music and multichannel audio with balanced tonal clarity. It combines an 8 in coaxial polypropylene woofer with an NBR surround and a 3/4in pivoting dome tweeter to deliver broad frequency coverage. The design supports a clean midrange and detailed highs for home theater and distributed audio installations.
Key features include a coaxial woofer and pivoting dome tweeter, an extended frequency response down to 48 Hz, and an 87 dB sensitivity rating. The speaker has a nominal 8 ohm impedance and a recommended amplifier power range of 5 – 120 W. The CS Series is built to handle dynamic formats such as Dolby Digital and DTS while preserving instrument separation and clarity.
Performance specifications include a frequency response of 48 Hz – 20 kHz (+/- 3 dB), sensitivity of 87 dB (1 W / 1 m), and a nominal impedance of 8 ohm. The woofer uses a polypropylene cone with an NBR surround for durability and controlled excursion. These parameters produce reliable output levels and stable impedance for common AV receivers and amplifiers.
Connection to systems is via standard speaker wiring to the amplifier or receiver, and the passive crossover is optimized for the coaxial driver layout. The CS Series also supports configurations in the line that include dual voice coils and dual tweeters for specialized stereo delivery options from a single enclosure. The grille is white powder-coated galvanized steel and is paintable to match room finishes.
Practical applications include home theater front and surround channels, whole-house distributed audio, and dedicated listening rooms where discreet in-ceiling installation is required. The shallow mounting depth and finished grille keep installations low-profile while maintaining acoustic performance. The optional pre-construction bracket AC-CS-8R-PCB simplifies rough-in for new builds.
Installation is straightforward with a 9.625 in cutout and a mounting depth of 3.75 in, and the external diameter measures 10.625 in. The speaker is designed for indoor or covered outdoor environments when installed appropriately and offers durable construction for long-term performance. Refer to the manual for recommended amplifier matching and mounting best practices to achieve optimal results.
