Dayton Audio's PN470-8 18" pro woofer is designed to deliver reliable low frequency operation with extreme output capability and minimal power compression. Featuring a 4" inside-outside wound voice coil, powerful neodymium motor, distortion reducing coppe


Dayton Audio left no boxes unchecked on the PN470-8 woofer. It features high power handling, 4" inner and outer wound voice coil, glass fiber former, powerful FEA optimized Neodymium motor, ribbed paper cone, and a copper cap on top of the extended pole piece. Thanks to the lightweight motor assembly, the PN470-8 is 30% lighter than a comparable ferrite driver making it "Roadie approved" and perfect for mobile DJs and portable PA systems. The PN470-8 is an ideal driver for any high output 2-way and 3-way speaker systems, bass bins, or horn loaded designs.

 

Lightweight but Powerful Motor Assembly

The lightweight but powerful neodymium motor assembly on the PN470-8 has been FEA optimized to provide a combination of low distortion and high efficiency. With the large neodymium magnet mounted inside the voice coil nearly all of the magnetic strength is concentrated into the magnetic gap providing up to 40% better utilization than conventional motor designs. The extended pole piece includes a large copper cap helping to lower distortion and linearize inductance.

Rugged Construction and Suspension

To stand up to the use and abuse of the professional sound environment Dayton Audio made sure the PN470-8 can take a beating. The cast aluminum frame uses 8 wide spokes to firmly support the motor assembly, and the thick mounting flange is reinforced to create an incredibly solid mounting surface. The cone, constructed of thick paper for a natural response, includes glass fiber reinforcement and uses a ribbed design offering additional structural support. Supporting the cone is a heavy spider with integrated silver tinsel leads and triple roll treated cloth surround, both designed for high excursion applications allowing the PN470-8 to handle short bursts of excessive power without damage.

High Power Handling and Low Power Compression

Along with high efficiency, you need a lot of power to achieve extreme SPL levels. Capable of handling up to 800 watts RMS and 1,600 watt peaks, the PN470-8 can take the heat. The 4" voice coil uses a vented fiberglass former with an inside/outside winding configuration which doubles the coil's exposed surface area for improved heat dissipation. The motor assembly includes a large pole vent along 8 large peripheral vents in the voice coil gap to keep fresh air moving across the coil keeping temperature at a minimum. Finally, the frame has venting behind the spider with integrated heatsinks removing as much heat as possible from the sensitive motor and voice coil.
