APPLICATIONS

Atlas Sound, the most respected name in paging loudspeakers, offers
Models APX20TN and APX40TN conservatively-rated, 20-watt and 40­watt, constant-directivity paging loudspeakers for use in public
address or paging applications. They combine constant-directivity with
superior engineering design, achieving extraordinary performance with
quick and easy installation. These constant-directivity loudspeakers
offer exact positioning flexibility with a simple twist of the wrist. The
APX loudspeakers are well-suited for indoor applications including
commercial, light industrial, and large retail/distribution applications
where clear and pleasant indoor paging/communications and security
are required. The speakers are also appropriate for installation in out­door retail, commercial, recreational, and public use areas where
dependable weatherproof performance is needed for communications
and security. The neutral-grey finish compliments most interior or exte­rior surroundings. It may also be painted to match installation guide­lines or cosmetics.
