Product Details

Radian 651PB-8 2" Aluminum Horn Driver 8 Ohm 4-Bolt

The 651PB, with a 3” diaphragm, represents the refinement of Radian's design efforts in 2” exit-format compression driver technology. Superior sound quality, unparalleled power handling, extended high frequency response, and high reliability make Radian compression drivers the preferred choice of loudspeaker systems manufacturers, consultants, contractors, designers, and engineers around the world.

Specifications: • Power handling: 50 watts RMS/100 watts program above 1 kHz/24 dB slope • VCdia: 3" • Impedance: 8 ohms • Frequency response: 500-20,000 Hz • SPL: 110 dB 1W/1m • Dimensions: 6.5" diameter x 2.62" depth • Net weight: 9 lbs. • Replacement diaphragm available.

Over a decade ago, Radian Audio Engineering went into business with a commitment to manufacture loudspeaker components that accurately reproduce the full frequency range of the audio spectrum. They began by building coaxial loudspeakers and compression drivers. The Radian 450PB, 465PB and the 475PB, with a 1.75” diaphragm, represent the refinement of their design efforts in 1” exit-format compression driver technology. All Radian compression drivers feature heat-treated structural alloy aluminum diaphragm domes which form an optimum balance of strength and low weight. This is a key factor in extending high frequency response.

Radian diaphragms utilize a Mylar® surround, which not only enhances the diaphragm’s reliability, but eliminates fatigue which destroys other compression driver diaphragms. In addition to being virtually indestructible, Mylar® surrounds provide excellent dampening characteristics which translate into smooth, low-distortion, linear output devoid of the resonant peaks typically present in diaphragms made with metal surrounds. Beyond the obvious advantages of our Mylar®-aluminum composite construction, Radian diaphragms utilize high temperature voice coil formers and advanced adhesives which allow Radian compression drivers to sustain high RMS and peak power levels over extended periods of time.

Radian diaphragm assemblies are self-aligning and may be rapidly serviced in the field by simply removing the three screws on the driver’s backcap and replacing the old unit with the new one.

Superior sound quality, unparalleled power handling, extended high frequency response, and high reliability make Radian compression drivers the preferred choice of loudspeaker systems manufacturers, consultants, contractors, designers, and engineers around the world. They are ideal for use in high output, high power touring sound systems and stage monitors, while their low distortion, high fidelity, and linear response deliver clear, crisp music and speech for theatrical, auditorium, stadium, convention and church installations.

Reviews

Radian 651PB-8 2" Aluminum Horn Driver 8 Ohm 4-Bolt
Radian 651PB-8 2" Aluminum Horn Driver 8 Ohm 4-Bolt is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Great DriverI have these Radian 651PB drivers connected to 17 inch wide, deep throat, horns in a two way system with a 12" woofer. I have the system crossed over at 1000Hz. I love the smooth natural sound from this system. I believe with the proper matching and crossover adjusting of these drivers, one could make a loudspeaker system that could turn the heads of audiophiles in a blind test. Horns produce a different sound that I prefer over the dome tweeters. I didn't rate the 651s a 5 only because Radian's more expensive 850PB may sound better.
