Product Details

Dayton Audio DC300-8 12" Classic Woofer

Dayton Audio Classic Series woofers are excellent for use as replacement speakers or for new loudspeaker system design and construction. The DC300-8 12" 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 0.43 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.

Rated 4 out of 5 by from Great replacement for DLK2I bought these to replace my damaged DLK2 woofers, they fit right in the cutout and bolted right it, the sound was very close to the old drivers, easy fix.

Rated 5 out of 5 by from Amazing bass!Bought these to replace a worn out pair of 12" 'ers in a pair of 3 way speakers. Bass response is amazing now, shakes the whole shop at work. Just now I need to replace the mids and tweeters too, to match the quality of bass they're now putting out

Rated 5 out of 5 by from Quick Delivery and Easy InstallJust dropped a pair of these in my old (circa 1974) Fisher XP7S' and now they're as good as new! They arrived the day after I ordered them and I removed the old speakers and installed the Dayton's in less than 10 minutes. Will probably replace the mids and tweeters shortly.

Rated 5 out of 5 by from Nice Woofer.This woofer has very good sound and frequency response. It goes down to 25 Hz eliminating the need for a subwoofer and goes high enough in frequency response to be used in a 2-way application.

Rated 5 out of 5 by from good replacement speakerBought these to replace a couple of toasted woofers in my 70's ESS Lab Series speakers. After visiting with customer assistance about dimensions and specs he recommended these Daytons. Mounted easily and sound terrific. Very happy with the sound of these woofers.

What woofers would you recommend as a drop in replacement for a 12" M&K V1B subwoofer speaker that has seen better days. I was looking for dual voice coil like the original speaker, but willing to hear your opinion on that. Thank You :)

Hi, can you recommend replacement midrange and woofers for Rectilinear III Highboy speakers? The originals were replaced with non-OEM drivers...and now THEY are shot. All other components (tweeters and crossover) are fine. Thx in advance!
