Electro-Voice PRO-8A 30-Watt 8" 2-Way Coaxial Ceiling Speaker with Dome Tweeter, 80-16000Hz Frequency Response, 8 Ohms Impedance, 96dB Sound Pressure Level, Single

The Electro-Voice PRO-8A (Single) is an 8", 8 Ohm, 2-way coaxial loudspeaker designed for professional high quality distributed sound systems. It is 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-speakers 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 a pole piece of the woofer. The small size of the tweeter eliminated the usual high frequency beaming, while being mounted to a stationary surface minimizes intermodulation 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 woofer voice coil and the tweeter.
