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.
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.
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.
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.
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.
