Product description

Most 12-Inch Subwoofers Prioritize Output Over Accuracy

A lot of subwoofers are designed to produce excessive bass without control.

That usually creates:

  • Muddy low frequencies
  • Poor musical detail
  • Loose bass response
  • Distortion at higher volume

The Sony XS-W124ES 12 Inch Mobile ES Subwoofer is engineered differently.

It is built to deliver deep, controlled bass with premium sound quality performance.

  • Low distortion performance

Built with Mobile ES Engineering
