Dayton Audio TCP115-4 4″ Treated Paper Cone Midbass Woofer 4 Ohm
 
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 for use in smaller 2-way designs.
Key Features
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
 
Dayton Audio TCP115-4 4″ Treated Paper Cone Midbass Woofer 4 Ohm
 
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 XMAX. 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.
