Dayton Audio, 295-046, PN470-8 Neo Series Pro 18" Woofer with 4" Voice Coil 8 Ohm
Features:
- 4" diameter inside/outside wound copper voice coil on a glass fiber former
- Powerful FEA optimized Neodymium motor system (Bl over 25 TM)
- High efficiency (97dB SPL at 2.83V/m) for amazing output capability
- Generous 6.5 mm of Xmax with 48 mm peak-to-peak excursion before damage
- Large copper cap for inductance control and low distortion
- Durable fiberglass-reinforced ribbed paper cone for rigidity and natural sound
Dayton Audios PN470-8 18" pro woofer is designed to deliver reliable low-frequency operation with extreme output capability and minimal power compression. Weighing only 16.5 lbs and featuring a 4" inside-outside wound voice coil, powerful neodymium motor, distortion-reducing copper pole cap, great excursion capability, and high power handling, the PN470-8 will produce extreme output levels with low distortion without breaking the bank or your back.
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 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 the temperature at a minimum. Finally, the frame has to vent behind the spider with integrated heatsinks removing as much heat as possible from the sensitive motor and voice coil.
