Alpine SWR-10D4 25cm Type-R Subwoofer The Alpine SWR-10D4 25cm Type-R Subwoofer is a re-designed fifth-generation Type-R subwoofer. The enhanced features will provide even cleaner, deeper bass extension, fast, more accurate transients and greater output capability. The new compact design offers more installation flexibility and application versatility. The FEA-Optomized Motor Structure together with the revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives this Type-R Subwoofers the highest X-max and SPL output in its category. A real-world, measured 21mm of X-max will deliver the best-in-class bass output, ultra-low distortion and unparalleled sound quality. The incorporation of Alpine’s Patented Radial Vented VC Heatsink and Airflow Management System will help to minimize power compression and ensures reliable long playing time by actively eliminating output-robbing heat away from the Voice Coil. The new one-piece cast aluminum frame with integrated shorting sleeve uses the entire frame as a heatsink allowing sustained power output and handling. The inclusion of Alpine’s Patented Compound Radius Curve pole geometry will ensure an ultra symmetrical magnetic field. This will allow you to optimize flux density to greatly reduce distortion while improving power handling and output. The oversized 65 mm voice coil allows for increased power handling of 600W RMS/1800W Peak. It comes complete with High-Amplitude Multi Roll Surround Design allowing for extreme excursions without sacrificing valuable cone area. The HAMR surround is FEA Optimized for linearity and made with injection-molded Santoprene improving overall suspension for distortion-free control. Features Oversized Hairline-Textured Mica Poly Dustcap w/Kevlar Reinforced Pulp Paper Cone Body 2-Piece Parabolic Design Injected Molded Santoprene High Amplitude Multi-Roll H.A.M.R Surround Design 10 Segment High-Roll Progressive Design 180ºC High Temp Wire on Sprial-Cut Aluminum Bobbin 4-Layer Dual Voice Coil Design FEA Optimized Design w/ Compound Radius Pole Geometry Radial Vented VC Heat Sink and Airflow Configuration Cast Aluminum Frame Perimeter Vented Heat Transfer Integrated Shorting Sleeve and Airflow Management System Heavy Duty 8 gauge Push with Housing, Banana Plug Jumper Reinforced Layer Spider Integration Tinsel Leads Specifications Power Range: 250W-1000W RMS Power Handling: 1000W Peak Power Handling: 3000W Mounting Depth: 149mm Mounting Diameter: 231mm Displacement: 0.08cu.Ft.
