The New Sound of JBL: MS Series Subwoofers

JBL MS-12SD2 Subwoofer JBL MS-12SD2 Subwoofer Cone

The Cone

No sound system is complete without some seriously deep bass. The hard hitting 12" JBL MS-12SD2 subwoofer provides just that. The dual voice coils allow for greater flexibility and more wiring options.

  • Lightweight polypropylene cone
  • Double stitched laminated polyurethane and fabric surround
  • Peak power handling: 1800 watts
  • RMS power handing: 900 watts
  • JBL MS-12SD2 Subwoofer Connections

    The Details Matter

    JBL has carefully engineered and constructed the MS-12DS2 from the ground up to ensure use for years to come. The durable, light weight aluminum basket is nonferrous, which dedicates more magnetic power to the motor assembly.

  • 56 oz. Barium ferrit magnet structure
  • Silver-plated push terminals
  • Stitched tensil weaves
  • Vented pole piece
  • The Sound of quality

    Sonic Electronix, one of the leaders in car audio, recently visited Harman, the premium global audio and infotainment group, at their research and development locations in Northridge, California and Detroit, Michigan. The purpose of these visits was to utilize and combine the powerful brand of Harman and the industry leading knowledge behind Sonic Electronix to begin working together on developing future car audio projects.
