Fulcrum Acoustic has introduced a new coverage pattern for the AH series of coaxial horn loudspeakers with the release of the new AH66 that’s specified to provide 60- x 60-degree dispersion with control to below 400 Hz,
As with the other models in the series, the new AH66 utilizes proprietary Compression Head horn architecture that’s designed to deliver optimized low-frequency loading to its twin 10-inch low-frequency cone woofers.
In addition, a pair of proprietary Oculus phase plugs are employed with the woofers to extend their high-frequency response to “mesh” more smoothly with the loudspeaker’s 4-inch-diaphragm HF compression driver.
The AH66’s compact trapezoidal shape allows it to be mounted close to ceilings with minimal effect on sight lines. Go here for more specifics.
