Space Series 12-Inch Single 4-Ohm Low Profile Subwoofer

Enhance your vehicle's audio system with the Space Series Subwoofers, delivering powerful bass in a sleek, slim design. These subwoofers are engineered for maximum low-frequency output in shallow spaces, ensuring deep, rich bass with weather-resistant durability.

Features:

  • Low-Profile Shallow Mount Subwoofer
  • Fiber Matrix Injection Molded Polypropylene Cone
  • Weather-Resistant Design
  • 3-Layer High Temp Voice Coil Former
  • Optimal Thermal Efficiency
  • Wrap-Sealed Rubber Gasket to Protect Enclosure Interior
  • Removable Subwoofer Grille Included

Pairings:

  • A single Space Series 4 ohm subwoofer pairs fabulously with the ACM-2.300 or ACX-300.2 amplifiers for conservative to moderate listeners. For higher output levels, consider the LC-1.800.
  • LC-5.1300 or D-5.1300 amplifiers deliver rich, robust output, with channel 5 being an excellent match.
  • For systems with two Space Series 4 ohm subwoofers, LC-1.800 is recommended.
  • Consult an expert for configurations with three or more subwoofers.
