The AMK PT615  powered speakers feature a 15 watt Class D digital design amplifier with  > 75% efficiency. An identical unpowered speaker, the (USQ 615)  can be used as a remote.  AMK PT Series speaker assemblies provide quality performance, unobtrusive appearance, and easy installation in suspended ceiling applications. Systems include a choice of factory wired drivers and enclosures mounted to a fine perforated 2’ X 2’ grille.
The speaker is a full range, low distortion, coaxial transducer assembly.  The speaker combines high performance, power handling and a very smooth response. 
The loudspeaker driver, CX601, is one of the few transducers in the commercial sound industry that produces and meets the standards of recording studios. However, it is designed for overhead applications.
Excellent dispersion, wide bandwidth, and a smooth frequency response make this the top choice for today's overhead commercial applications.  There are wide ranges of the application for this unit, especially in educational markets and corporate boardrooms where direct input of the signal from the processor is desired (i.e., ceiling mount projector) They are shipped ready to install and require no speaker cut-outs in the tile or time consuming assembly.  2' x 2' Systems are designed to replace a standard 2' x 2' tile and are supported by the T-bar grid.
Assemblies include a factory wired speaker/transformer mounted to a 2' x 2' subplate with a fine perforated grille and mounted AMK powered speaker enclosure. The backbox is offset to one side of the 2' x 2' grille allowing it to be rotated in the ceiling to install around plenum obstructions. Several options are available for the line level audio and power connections. Each is designed and manufactured to assure consistent performance with clear intelligibility and wide dispersion.
Architectural Grilles feature a fine perforated pattern for a clean unobtrusive appearance. Grilles are engineered to provide maximum free-air space for excellent speaker sound transmission while achieving virtually invisible presentation of the speaker in new or exiting tile ceilings. 2' x 2' grilles simply replace a 2' x 2' tile. All are formed from perforated steel and finished in white powder epoxy for long lasting appearance.

Features

* Systems install quickly into suspended tile ceilings and are supported by the T-bar grid.
* Systems include a complete powered speaker with UL based plenum enclosure.
* Fine perforated grilles blend with ceiling tiles and provide excellent acoustic transparency.
* Self powered with 15 watt Class D amplifier
