Electro-Voice PRO-8A 8 inch 2 Way Ceiling Speaker (Discontinued)

The PRO-8A is an accurate, highly intelligible, and musical-sounding loudspeaker that is well-suited for the reproduction of voice and music.The PRO-8A employs an unusually large 1.5" voice coil. This coil provides increased apex-driving-point cone area and greater thermal capabilities.

The PRO-8A full-range reproducer is an 8", 8-ohm, 2-way coaxial loudspeaker designed for professional high-quality distributed sound systems. A developmental program combining state-of-the-art engineer¬ing techniques with extensive listening evaluations resulted in the PRO-8A being an accurate, highly intelligible and musical sounding loudspeaker that is well suited for the reproduction of both voice and music.

The PRO-8A represents a new concept in 8" ceiling speaker design. The woofer section employs a 1.5" voice coil. Large by ceiling-speaker standards, the oversized voice coil provides increased apex-driving-point cone area and greater thermal capabilities, enabling unusually high acoustic power output for this class of loudspeaker. At lower levels this translates to unmatched durability and reliability. The high frequencies are reproduced by a 1.5" piezoelectric tweeter that is mounted directly to the pole piece of the woofer. The small size of the tweeter (smaller than is typically used in ceiling speakers) eliminates the usual high-frequency beaming, while being mounted to a stationary surface minimizes intermodula-tion distortion. The tweeter being located at the apex of the woofer 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.
