FRX+660, FRX+660PI specifications

The Electro-Voice FRX+660PI and FRX+660 are powerful and versatile loudspeakers designed for professional audio applications, including live sound, installations, and events. Both models are engineered to deliver exceptional audio quality, reliability, and performance, making them ideal choices for sound professionals and musicians alike.

One of the standout features of the FRX+660 is its dual 6.5-inch high-efficiency woofers. These woofers are specifically designed to provide deep bass response and clear mid-range frequencies, ensuring a well-rounded sound profile that enhances any audio experience. In combination with a high-frequency compression driver, the FRX+660 achieves impressive clarity and detail across a wide frequency range, making it suitable for a variety of musical genres and speaking events.

The FRX+660PI variant comes equipped with an integrated passive crossover network that optimizes the performance of its components. This technology ensures a seamless transition between the woofers and tweeters, resulting in a balanced sound that maintains integrity at high sound pressure levels. This makes the FRX+660PI particularly well-suited for both foreground and background music applications, providing excellent intelligibility for speech and vocals.

Durability is another critical characteristic of the FRX+660 series. The cabinets are constructed from high-quality materials, including rugged plywood and a weather-resistant finish, making them suitable for both indoor and outdoor use. The speaker's design also includes a heavy-duty grille that protects the drivers from physical damage, ensuring that these speakers can withstand the rigors of constant transportation and setup.

Portability is enhanced with integrated handles and a lightweight design, allowing for easy transport and setup at events. The speakers also feature multiple mounting options, including pole mounts and rigging points, providing flexibility in positioning and installation.

The electro-acoustic performance of the FRX+660PI and FRX+660 is enhanced by advanced technologies such as optimized magnet structures and proprietary voice coil designs. These technologies contribute to lower distortion levels, increased efficiency, and improved thermal management, ensuring that the speakers can perform reliably even during extended use.

In summary, the Electro-Voice FRX+660PI and FRX+660 loudspeakers stand out for their exceptional audio performance, robust construction, and versatility, making them ideal for a range of professional applications. With a focus on sound quality, durability, and user-friendly design features, these speakers are poised to meet the demands of audio professionals and enthusiasts alike.
