Dynamic Balance Drivers:

  • Dynamic Balance is a proprietary Polk Audio technology using laser imaging to determine what combination of speaker materials create the least amount of resonance.
  • Eliminating resonance in speakers results in a wide, smooth response and low distortion.
  • Using just the right materials enables Polk to eliminate issues that reduce speaker performance and tune out performance-robbing resonances before they occur.
  • Dynamic Balance ensures a rich, clean, full-range sound no matter what you're listening to.
  • The Polk Signature S15 bookshelf loudspeaker incorporates a Dynamic Balance two-way driver array with one 1" tweeter and one 5.25" woofer.
