With high excursion capabilities and low Fs, Dayton Audio's TCP115-4 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

The TCP115-4 combines a large motor, 1" 4-layer voice coil, vented pole and a sizable rubber surround to make use of its 4 mm of x-max. This combination of features makes it a very versatile driver which can be used as a bass driver in a small 2-way system, center channel, or even portable Bluetooth speaker designs.



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