Product Description

The Dayton Audio PC105-8 4" full-range driver features a poly damped woven glass fiber cone, damped rubber surround, and high energy motor. Thanks to the vented pole piece and vented aluminum voice coil former the PC105-8 can handle up to 40 watts RMS for surprising output capability with minimal power compression. The addition of a copper cap on the extended pole improves cone control, lowers inductance, and decreases distortion allowing for improved high frequency response. Offering great full-range performance, controlled off-axis response, and high efficiency, this driver will provide impressive output for its size. Perfect for use in line arrays, sound bars, portable speakers, or even car audio systems, the Dayton Audio PC105-8 will deliver high fidelity and low distortion from compact applications.
