Two-Way Complex Conic Loudspeaker Systems

PN/PNX Series loudspeaker systems integrate the entire signal chain – from line level to listener – into a compact, two-way system.

Renkus-Heinz engineering begins with the highest quality components: advanced transducers developed with the world’s leading manufacturers, no-compromise analog and digital electronics, and our unique Complex Conic horns. From there, our proprietary design process creates the most transparent, uncolored systems available.

Reference Quality, Unparalleled Versatility

Non-powered PNX Series loudspeakers unite advanced technology and application-driven engineering to bring live sound closer to the ultimate reference point: reality. Cutting edge driver technology and unique innovations such as our Complex Conic Horns deliver natural sounding music and intelligible speech.

Wherever audiences and operators demand superior performance and ease of use, PNX loudspeakers are the choice for transparent, reference quality performance.

All PNX series loudspeakers are handcrafted especially for you in our Foothill Ranch, California facility. Numerous custom options are available.

The PNX81 features an 8-inch Heavy-Duty Woofer and 1-inch HF tweeter.
