TCP115-8 4" Treated Paper Cone Midbass Woofer 8 Ohm

Quick Overview

With high excursion capabilities and low Fs, Dayton Audios TCP115-8 can produce a surprising amount of bass for a 4" woofer. In addition to its low frequency performance, this driver also performs very well through the midrange, making this driver ideal for use in smaller 2-way designs.

Product Highlights

  • Powerful motor for efficiency and compact enclosure
  • 1" diameter 4-layer voice coil improves power handling and low frequency response
  • Aluminum former keeps voice coil cool for high power handling
  • Extended pole piece creates symmetrical magnetic field for lower distortion
  • Cosmetic low-profile mounting flange looks good without flush mounting
