Atlas Sound introduces constant directivity re-entrant horns

Atlas Sound introduces a new line of constant directivity re-entrant horns consisting of three new models in 90° x 40°, 60° x 40°, and 40° x 20° configurations. Offering greatly improved uniform sound coverage over conical designs, as well as predictable and tight pattern control; the horns, when ready for shipping later this year, will bear model numbers CD64, CD94, and CD42.

"Basically this is a completely new twist on a well-known story," explains Atlas Sound Senior Vice President of Design and Engineering Bruce Marlin, describing the evolution of the designs. "The concept of a constant directivity horn was well defined by Don Keele in the early '70s, and we're all familiar with it. What we've done today is simply taken the idea to the next level in the commercial market."

Typically, most constant directivity horns on the market today are outfitted with either a refraction slot or standard throat. Atlas Sound has added a re-entrant design to the equation giving the three new models increased air column length. Additional output and greater pattern control result when compared to traditional designs.

"This all translates into more efficiency," Marlin adds, "as well as a need for fewer and much smaller horns to achieve the same results of what formerly required larger horns. You obtain a much more impressive low frequency response and more sensitivity out of the driver as well, and the horizontal coverage pattern is more precisely controlled over the entire frequency range."

Ideally suited for paging, announcements, warning and signaling systems, and even music, the new Atlas constant directivity re-entrant horns are made from a polyester resin and fiberglass laminate. An integrally-molded die-cast zinc throat section is included in each design to accommodate Atlas Sound PD Series drives, as is a heavy-duty steel mounting bracket.

Existing within a class unto themselves in the marketplace, Atlas Sound's new constant directivity re-entrant horns, as well as the full line of Atlas Sound solutions, can be viewed online at www.atlassound.com.
