Product Research


Overview: Atlas Sound Strategy Series II in-ceiling speakers are designed for commercial, industrial, and institutional applications. They are known for highly detailed voice, music, and signal reproduction. The speakers feature a black frame, and can be easily installed in drop-tile or drywall ceilings using a number of mounting options. The included 24-gauge perforated steel grille has a black epoxy finish, and simply press-fits into the speaker.

Drivers: The Atlas Sound FAP42T-B is equipped with a 4" polypropylene woofer with a 1" voice coil, and a Butyl Rubber surround. The 19mm (3/4") PEI dome tweeter is coaxially-mounted over the woofer. The drivers are housed in a low-profile 285 in³ optimally tuned and ported, deep drawn, galvanized metal enclosure.

Wiring Options: The FAP42T-B has a removable 4-pole Phoenix style / Euro connector for 70.7V, 100V, or 8Ω applications. This type of connector allows you to conveniently pre-wire the speaker connections, then simply plug them in when installing the speakers. The connector can accept bare wire up to 14-gauge speaker wire. The speaker is equipped with line matching transformers, requiring an amplifier capable of driving a 70.7V/100V line. Depending upon the amplifier's wattage rating and the number of speakers being driven by the amplifier, you can select a 1, 2, 4, 8, or 16-watt tap at 70.7V/100V. The tap selector is conveniently located on the front of the speaker, allowing you to set or change the taps without removing the speaker. You can also bypass the line transformers and connect the speaker to a consumer amplifier (the speaker has an 8Ω impedance).

Speaker Placement: The Strategy Series II in-ceiling speaker mounts easily into existing construction drop ceiling or drywall with the provided tile bridge assembly. The tile bridge assembly consists of two V-shaped mounting rails and a C-ring assembly. "Dog Leg" tabs hold the speaker securely in place. For new construction drywall applications, the optional FAP42-TR trim ring may be used to mark the location for drywall installers to cut around. Mounting holes in the trim ring accommodate 16" or 24" on-center joist mounting. The top of the FAP42T enclosure includes a support ring for attaching the mandatory auxiliary support cable for drop ceiling installations for safety and seismic considerations.
