1 Question, 1 Answer or
The Wavecor SW223BD02 is an 8-3/4" aluminum cone subwoofer that was designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities. The SW223BD02 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
  • Very rigid black aluminum cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
  • 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
  • Large motor with 2” voice coil diameter for better control and power handling
  • Vented center pole with dual flares for reduced noise level at large cone excursions
  • Conex spider for better durability under extreme conditions

Overview

Wavecor SW223BD02 8-3/4" Black Aluminum Cone Subwoofer 4 Ohm

The Wavecor SW223BD02 is an 8-3/4" aluminum cone subwoofer that is equally at home in a home theater or hi-fi installation. This driver utilizes a rigid black aluminum cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels. 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 SW223BD02 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.
