Electro-Voice PRO-8AT5
8" 2-way Ceiling Speaker with Transformer

PRO-8AT5

The PRO-8AT5 is a low-power transformer version of the PRO-8A. The PRO-8AT5 allows for connection to 25-, 70.7-, or 100-volt systems of 0.62 to 5 watts.

The PRO-8A is an accurate, highly intelligible and musical sounding loudspeaker that is well suited for the reproduction of both voice and music. The PRO-8A employs an unusually large 1 1/2" voice coil. This provides increased apex-driving-point cone area and greater thermal capabilities. The result is higher acoustic power output than other brands, which translates into unmatched durability and reliability at lower levels. High frequencies are reproduced by a 1 1/2" piezoelectric tweeter that is mounted directly to the pole piece of the woofer. The tweeter being mounted to a stationary surface at the apex of the woofer minimizes intermodulation distortion and allows for improved time alignment over other coaxial ceiling speaker designs. An acoustically transparent dust dome mounted on the woofer cone encapsulates the tweeter offering excellent dust protection for both the woofer voice coil and the tweeter. The PRO-8A series of speakers may be used in ported enclosures where improved low-frequency response is desired. Placing the loudspeaker in an enclosure of 1.0 cubic foot with a box-tuning frequency of 75 Hz will yield a -3 dB point of 80 Hz. An 80 Hz tuning may be optained with a port having an area of 7.0 square inches and a length of 0.75 inches.
