Brand NEW!
With high excursion capabilities and low Fs, Dayton Audio's 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.

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
