Community D4 4.5" 2-Way Ceiling Speakers
The smallest member of the D series, the D4 possesses the advanced features of its larger siblings with performance that belies its small size. Suitable for paging, background music, or to augment larger systems, the D4 is a versatile performer. It installs quickly and provides exceptionally uniform coverage with excellent sonic properties.
Uniform voicing among the Distributed Design product family makes for an easy match to the other models in the series, while a host of design innovations set the D4 apart from other products in its size and price range. Featuring genuine coaxial design with separate magnets for the LF and HF drivers, the D4 exhibits reduced distortion and industry-leading sensitivity permitting 3 dB to 6 dB greater output level, while requiring half the amplification power of competing products.
The proprietary Tru-Phase™ waveguide and perfectly centered driver produce a consistently wide conical polar response up to 16 kHz. Community's patented Carbon Ring Cone Technology™ increases the effective cone area to further reduce distortion while reinforcing the cone for improved durability. Exclusive Drop-Stop™ and Twist-Assist™ tabs allow single-handed placement to speed installation and reduce labor time. Drop-Stop's spring-loaded legs support the back can on the included tile rails and snap-on C-ring, so that the installer no longer needs to hold the can against the tile while tightening the clamps. Twist-Assist performs a similar function for the baffle assembly: when the loudspeaker back cans are pre-installed into a conduit system for termination at a later date, a simple twist of the baffle into the back can brings the Twist-Assist clips together, supporting the baffle assembly while the installer fastens the screws.
The front-face wattage selector switch enables quick adjustment of 70V/100V tap levels. A variety of installation accessories are available to accommodate different ceiling materials. The D4 face-only assembly and back can are also available for separate purchase.- Features
