Denovo Audio PS74-4 Point Source 2-1/4 inch Full Range Driver - 4 ohm

Denovo Audio set out to fill the missing link in small full range drivers with their beautifully engineered 2-1/4 inch PS74-4 point source woofer. A great performer that also looks amazing. This full range uses a compact yet powerful neodymium magnet that's encased in a specially designed cast aluminum frame. The frame design helps with cooling, venting, and also reduces back-wave reflections. A custom curvilinear rubber surround allows sound to flow smoother from the paper cone which significantly reduces diffraction issues. A copper-anodized phase plug controls dispersion and gold plated terminals allow for easy hook up.


Performance:

  • Incredibly flat full-range frequency response.
  • Neodymium magnet to increase efficiency and reduce distortion.
  • Paper cone for a smooth natural sound characteristic.
  • Increase X-max for more bass output potential.
  • Custom phase plugs to enhance off-axis dispersion.
  • Custom curvilinear shaped rubber surround smooths the transition from the cone giving a flatter response.
