Technology meets the challenge in a tough arena.
Holosonics has an interesting new concept for beaming sound into a specific area with minimal acoustic spread to the surrounding area in the Audio Spotlight AS-24. From a height of about 12ft., the unit spots a 1kHz tone with a 20dB drop beyond a 3ft. radius. The system consists of the transducer unit and the matching Sound Beam processor/amplifier.
Introduced this year, the Control 47CT from JBL features the Conical Radiation Boundary Integrator (RBI) adapted from the JBL VerTec series of line arrays. This design combines a large-diameter HF waveguide and LF projection apertures to allow 120 degrees of coverage over a wide frequency range to allow fewer loudspeakers to cover more area.
For whole house audio systems, Klipsch offers the CDT-5650-C with separately pivoting 1in. titanium tweeter and 6.5in. cerametallic woofer. The tweeter and its tractrix horn swivels 100 degrees while the woofer can rotate 360 degrees and shift 15 degrees in any direction. They provide a frequency response of 60Hz to 20kHz ±3dB at 8Ω with program power handling at 50W and 200W peak.
Leon Speakers offers its 6in. model in the Axis series, the Axis AX-61with a silk dome pivoting tweeter and Leon's Acoustic Resonance Control (ARC) technology to eliminate standing waves. The 70W, 8Ω unit has a frequency response of 85Hz to 20kHz and provides 90dB SPL at 1W/1 meter.
The weather-resistant construction of the Mirage Omnican OC-55 allows a wide range of installation options aided by the rotatable OmniGuide module for selectable directivity. The 8Ω unit can work with power amps delivering from 10W to 125W and deliver 80Hz-to-20kHz frequency response. It also features a paintable grille and bezel.
