500 Series

Best in Class

Redline 500 Series 12" Subwoofer

The 500 series is one of the best performing subs you can find in its power class. With a highly efficient design, the 500 series can easily be driven to high output levels on as little as 150-400 Watts. When compared to the 200 Series the 500 Series uses a longer coil, more powerful motor and the suspension is designed to handle higher transient peaks. These are very versatile subs that work well in sealed enclosures while providing the extra energy and control needed for vented enclosures applications.

500 Series Features:

  • EROM surround
  • High-temp, 2.0”, voice coil
  • Double Layer Deep bass, high excursion spider system
  • Unique glass fiber and natural pulp cone
  • Back plate coil gap venting
  • Extended pole piece
  • DD stamped steel basket (508-512)
  • DD cast basket (506)

REDLINE EROM Surround
Less -

EROM (Extended Range Of Motion) surrounds, pioneered by DD in the early 90’s, allow our subs to have higher, more linear excursion with more cone area than subs using wider surround profiles. Simply put, this surround design allows our subwoofers to make more and better bass than other subs out there. In fact, we like this surround style so much that some variation of it is used on all levels of our subwoofers. The REDLINE EROM surround features new signature aesthetics including a red accent line pressed into the surround and an embossed REDLINE logo.
