Wavecor SW182BD03 7" Balanced Drive Black Aluminum Cone Subwoofer 4 Ohm

Wavecor
Part #298-1056  
Model: SW182BD03
The Wavecor SW182BD03 is a 7" aluminum cone subwoofer that was designed specifically for high performance compact subwoofer applications where sound quality and low distortion are the priorities. The SW182BD03 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 aluminum cone to ensure piston motion at high levels and for better heat transfer at high continuous power levels
  • 4-layer voice coil for increased control and better small-cabinet performance
  • Built-in aluminum field-stabilizing rings for reduced distortion at high levels
  • Rigid die cast aluminum 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
  • Vented voice coil former for reduced distortion and compression

Overview

Wavecor SW182BD03 7" Balanced Drive Black Aluminum Cone Subwoofer 4 Ohm

The Wavecor SW182BD03 is a 7" aluminum cone subwoofer that is equally at home in a home theater or hi-fi installation. This driver utilizes a rigid aluminum cone that is also designed to reduce distortion. The aluminum field-stabilizing rings and balance drive technology also aid in distortion reduction. The SW182BD03 offers extremely low mechanical losses which allows for great performance in low volume or extreme dynamic situations.

The SW182BD03 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.
