Description

The 15" High Output version of Dayton Audio's Reference Series subwoofer, built for ultra-low distortion: three short-circuit paths in the motor keep second, third and intermodulation distortion low. A durable aramid fibre spider and extensive venting give quiet, even excursion. The HO version is designed for car audio or equalised high-power home subwoofers.

Features

  • Extensively vented motor eliminates compression and allows quiet excursion
  • Extra-thick black anodised aluminium cone for maximum rigidity
  • Triple shorting ring motor for ultra-low distortion
  • 4-layer coil for high power handling
  • Optimised parameters for small enclosures
  • Highest quality materials throughout for long-lasting performance
