Rockford Fosgate has taken their P3 subwoofers to the highest level. The Stage 3 subwoofers offer deep bass and unparallelled quality with the best features. These subwoofers accept up to 500 watts of power RMS, the reinforced Kevlar 15" cone provides excellent sound quality with minimal distortion. The new dual linear spider keeps the cone in perfect alignment and allows for high excursion levels. Checkout all of the features of the P3D4-15 15" subwoofer.Anodized Aluminum Voice Coil Former
Heat is the #1 concern with subwoofers, dissipating the heat is the challenge. Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide excellent heat dissipation. Aluminum is an excellent heat-sink and allows the Rockford P3D4-15 subwoofer to stay cool during high volume conditions. The high-temperature voicecoil is designed with a Nomex reinforcement collar and meant to handle even the loudest volume levels.CEA-2031 Compliant
The Rockford Fosgate P3D4-15 conforms to CEA-2031 industry standards. This means your 15" subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time can damage voice coils.VAST Surround
V.A.S.T. Stands for Vertical Attach Surround Technique, this technology significantly increases a subwoofer's effective radiating cone area up to 25%. This design allows for more output from an equivalent speaker size without increasing installation challenges. This is done by eliminating the large flat glue surface area (the landing), which allows the surround to be shifted for increased cone area. This improves efficiency and output dramatically.Stitched Tinsel Leads
To reduce fatigue and prevent catastrophic damage from shorts the P3D4-15 15" subwoofer uses stitched tinsel leads. By using this technology fatigue on the leads is dissipated over a greater area which improves the life of the subwoofer and contributes to a robust design.Rockford Fosgate P3D4-15 15" Punch P3 4-Ohm DVC Subwoofer:
