The PRV Audio FR Series sets a new standard of value in high-performance Full Range drivers. The 8FR250 full-range driver is an excellent choice when space is at an absolute minimum, eliminating the need for a tweeter.

This loudspeaker has a dual cone design, the primary cone handles low to midrange frequencies while the smaller secondary cone increases high-frequency response from 50 Hz to 18,000 Hz.
The combination of a low-distortion motor system with a copper ring and a unique woven-cloth dust cap provides exceptional clarity, detail, and dynamics at an impressive 93.5 dB of sensitivity.
