Reference Series

BLACK in-wall and in-ceiling speakers perform a near miraculous disappearing act. Rather than a wide flange found on most built-in speakers, BLACK speakers feature flange-free Perfect Edge™ magnetic grilles that minimize the visible footprint of the speaker for a clean, elegant and unobtrusive appearance.


BLACK by Optimal Speaker Design is a range of premium quality flush mount loudspeakers designed to serve discriminating homeowners and A/V integrators who demand the ultimate in aesthetic style and audio performance. BLACK products includes unique features and technologies that make them better looking, easier to install and more durable, while delivering lifelike sound quality more typically found in free-standing audiophile grade speakers. There are BLACK models to fit every distributed audio and home theater
application and space, offered in three performance levels: Acoustic, Performance and Reference. BLACK products are sold only through custom installation Audio Video specialist dealers in order to ensure proper system design, installation and total customer satisfaction.

Built-in Theater

Exceptional home cinema audio performance with near invisibility is now within reach.
BLACK offers both in-ceiling and in-wall high performance speakers specifically designed
for multi-channel home theater applications. The R62A and R63A models are 6-1/2” two-way
speakers with angled drivers and specially contoured baffles to focus sound at screen
level for a perfect illusion that the speakers are in front of the screen. The T53LCR is a Reference series in-wall speaker that may be used vertically as left/right speakers and horizontally as a center speaker.

TPR Rubber Surround

For installs in tough environments such as indoor pool areas, outdoors under eaves and
commercial settings, use BLACK Reference series models. Their woofer surrounds are fabricated from injection molded Thermoplastic Rubber (TPR) – a copolymer that has superior damping characteristics and greater resistance to chemicals, UV and pollutants.

Custom crossover

BLACK Reference and Performance models feature audiophile-grade crossover components including Mylar bypass capacitors to enhance high frequency extension for exceptional clarity and “air.” Shields* protect the components from debris and suffocating insulation while integrated air vents keep things cool.

Contour Switch

Reference and Performance speakers offer a high frequency contour switch with -3dB,
0 (flat) and +3 dB settings to match speaker performance to the room acoustics. Highly
reflective “live” rooms benefit from a -3dB HF reduction while fabric-heavy “dead” rooms will
sound better with tweeters boosted +3dB.

Pro Mounting

Installers will appreciate the BLACK mounting system for its ease and robust construction.
BLACK’s rotating clamps have brass inserts to prevent thread stripping. The stainless steel
machine bolts are thread-strip and rust resistant. Rubber damping pads on the mounting
clamps minimize the likelihood of sheetrock blowout and damp resonance, vibration and
buzzing. Better installs, better sound, it’s all better with BLACK.
