The 600 Series is a great entry point for a higher performance system design that keeps the vehicle as close to stock as possible. These subs will perform like a boss on as little as 300-600 Watts, meaning even multiple woofer systems can be driven with one moderate powered amplifier. This keeps electrical upgrades minimal with less added strain on the vehicle. With a high energy, double stack motor paired with a laminated triple layer poly cotton spider suspension the 600 Series works best with vented and multi-order enclosures.

Features:

  • EROM surround
  • High-temp, 2.5”, voice coil
  • Triple 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 (610-612)
  • DD cast basket (608)
