Dayton Audio Classic Series woofers are excellent for use as replacement speakers or for new loudspeaker system design and construction. The DC380-8 15" woofer has developed quite a reputation for having the best bang-for-the-buck performance and value available anywhere. Smooth frequency response and extended bass performance make this driver ideal for use in large format two-way and classic three-way loudspeaker designs. A Qts of 0.35 allows the DC300-8 to work well in both sealed and ported speaker enclosures.

A non-pressed treated paper cone allows for smooth frequency response, while the high temperature aluminum voice coil and vented pole piece combine to increase power handling without compression. Longevity is ensured with the use of a rubber surround, treated cloth dust cap, and an extended bump plate.
