Alpine 12" Type-E Series Black Subwoofer - SWE12S4

Alpine 12" Type-E Series Black Subwoofer - SWE12S4

Turn up the volume and crank that bass without putting a large dent in the bank account. The new Type-E subwoofers now have proven high performance technology and new rugged materials to outperform and outlast any subwoofer in its class.

• More Bass In Less Space
  What is unique and amazing about the new Type-E subwoofer is not only the engineering behind the build, it's the new requirements for them to optimally perform. The new Type-E 10” specification requires 0.5 – 0.85 cubic feet air space for superior performance. That’s 34% less air space used in your vehicle!
  
  
• Progressive Conex® Spider
  This woofer uses a durable Conex spider to ensure reliability and helps avoid interference typical of many high-excursion designs.
  
  
• Leading the Class with Output
  Get bass you can not only hear, but also feel? Through its new optimized suspension design and new cone materials, this woofer allows over 55mm peak-to-peak cone travel. Now that’s woofer movement you’re sure to feel!
  
  
• High Strength Steel Frame
  With such an advanced airflow system we have incorporated a high strength steel frame to keep the bass going while keeping your sub cooler.
  
  
• Improved Power Handling
  The oversized 65mm voice coil with high-temp 3-layer SVC winding on a spiral cut aluminum former offers increased power handling to 250W RMS / 750W Peak. To get the best performance, we recommend you pair Type-E subs with Alpine’s new MRX digital amplifiers.
  
  
• 8 AWG Push Terminals
  Keeping power consistent to your woofers is just as important as keeping them cool. The 8 AWG Push Terminals are used on the Type-E woofers to keep power current flowing, allowing your subwoofer to get the power needed from the amplifier to run cool and consistent.
  
  
• High-Grade Strontium Ferrite Magnets
  Creates a symmetrical magnetic field with evenly distributed flux density to greatly reduce distortion, while further improving power handling and output.
  
  
• Clean, Concealed Mount Gasket System
  These subwoofers have a shallower mounting depth allowing for more application flexibility and the concealed mount gaskets give Type-E subs a clean finished appearance for any vehicle.
