8½” High Performance Steel Frame Subwoofer Unit.
Suitable for dedicated subwoofer applications  and as low frequency transducer in 2½-, 3- and multi-way speaker systems.

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • Large linear stroke, ensuring low distortion at high output levels
  • Rigid air-dried paper cone to ensure piston motion even at high levels - for reduced distortion
  • Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
  • Vented center pole with dual flares for reduced noise level at large cone excursions
  • Heavy-duty fiber glass voice coil former to reduce mechanical losses resulting in better dynamic performance and low-level details
  • Large motor structure for better control and power handling
  • Built-in alu field-stabilizing ring for reduced distortion at high levels
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Black plated motor parts for better heat transfer to the surrounding air
  • Conex spider for better durability under extreme conditions
  • Gold plated terminals to ensure long-term trouble free connection
  • Delivered with foam gasket attached for hassle-free mounting and secure cabinet sealing
