Wavecor SW270WA01 10-1/2" Balanced Drive Paper Cone Subwoofer 4 Ohm

WavecorPart # 298-1072
Model: SW270WA01
The Wavecor SW270WA01 is a 10-1/2" air-dried paper cone subwoofer that was designed specifically for high performance subwoofer applications where sound quality and low distortion are the priorities. The extensive venting on the frame allows for optimal cooling.

Key Features

  • Balanced Drive motor structure for optimal drive force symmetry resulting in largely reduced even order harmonic distortion
  • Very rigid air dried paper cone to ensure piston motion at high levels for reduced distortion
  • Low-loss suspension (high Qm) for better reproduction of details and dynamics
  • New reinforced die cast aluminum chassis with optimal ventilation and increased stroke
  • Large motor with 2” voice coil diameter for better control and power handling
  • Built-in aluminum field-stabilizing ring for reduced distortion at high levels
  • Vented center pole with dual flares for reduced noise level at large cone excursions

Overview

Wavecor SW270WA01 10-1/2" Balanced Drive Paper Cone Subwoofer 4 Ohm

The Wavecor SW270WA01 is a 10-1/2" paper cone subwoofer that is equally at home in a home theater or hi-fi installation. This driver utilizes a very rigid air dried paper cone to ensure piston motion at high levels for reduced distortion. The aluminum field-stabilizing rings and balanced drive technology also aid in distortion reduction. The SW270WA01 offers extremely low mechanical losses which allows for great performance in low volume or extreme dynamic situations.
