WavecorPart # 298-1062
Model: SW215WA02
The Wavecor SW215BD02 is an 8-1/2" paper cone subwoofer that was designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities. The SW215BD02 utilizes balanced drive motor technology for dramatically reduced distortion.

Key Features

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • Rigid air-dried paper cone to ensure piston motion even at high levels - for reduced distortion
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • Rigid steel chassis with extensive venting for lower air flow speed reducing audible distortion
  • Conex spider for better durability under extreme conditions
  • Vented center pole with dual flares for reduced noise level at large cone excursions
  • Large motor structure for better control and power handling

Overview

Wavecor SW215WA02 8-1/2" Balanced Drive Paper Cone Subwoofer 8 Ohm

The Wavecor SW215BD02 is an 8-1/2" paper cone subwoofer that is equally at home in a home theater or hi-fi installation. This driver utilizes a rigid air-dried paper cone that is also designed to reduce distortion. The aluminum field-stabilizing rings and balance drive technology also aid in distortion reduction. The SW215BD02 offers extremely low mechanical losses which allows for great performance in low volume or extreme dynamic situations.

The SW215BD02 is ideal in 2 or 3-way designs when being used as a woofer or a low frequency driver. With the attached foam gasket, this driver is easily mounted in several different methods.
