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.

Dayton Audio DC300-8 12" Classic Woofer
Dayton Audio DC300-8 12" Classic Woofer is rated 4.4571 out of 5 by 70.
Rated 5 out of 5 by from NIRVANA--but always replace in pairs.This woofer completely resurrected a circa-1980 AAL floor speaker for a very modest price. Second-day delivery and a perfect drop-in fit were pleasant surprises about Parts Express, which is a new vendor for me.Replacing only one speaker, however, merely highlights the shortcomings of the other member of the pair. So I bought another with the same good result. Lesson For Me → Always replace stereo speaker components in pairs!

Rated 5 out of 5 by from Way better than the original!I have been hanging on to a pair of vintage BIC Venturi Formula 6 speakers that my dad had bought new in 1975, with burned out woofers. These speakers sounded amazing and are worth holding on to. To my dismay, the correct replacement woofers are not available and anything reasonably close is very expensive. With this in mind, I decided to do a resto-mod and replace them with drivers with a rubber surround instead of the cloth. Best decission I've made for these speakers.Eric was invaluable in me selecting the correct replacement, and SAVED me a boatload of $$$!!! Although I had to do some minor modifications to mount the drivers, the end result was nothing short of fantastic! The bottom end extended much farther than the originals ever could, and they sound totaly natural (not exagerated or boomy).I now have an awesome set of speakers, again...Thank you PE and Eric.

Rated 2 out of 5 by from OkayBought a pair of these to replace my blown original woofer. I have Infinity SM-122 speaker towers on my wall at home. I had to make my woofer hole larger to accommadate the size, but only slightly, about 1/4 inch all around. To me they lack the punch my original ones provided.

Rated 5 out of 5 by from Great Advent Replacement WooferI used the Dayton 12" classic to replace the original 10" wooferd in my vintage Advents. The Advent Loudspeaker used a 10" size cone in a 12" frame, so most standard 12" woofers will drop right in. Out of the box and installed I'm pleased with the bass. Rubber surrounds typically need a break in period, so they will only improve as they get some use. A good sounding hi-fi replacement woofer without breaking the bank is a winner in my book!

Rated 5 out of 5 by from Excellant response!I used these woofers to replace defectives in an old and obsolete JL Audio pair of speakers, they are crisp and tight with excellent bass response. I was very pleasantly surprised at just how great they sounded.

Rated 5 out of 5 by from Great WooferA very good replacement woofer for my 12 inch 3-way Sony Speakers SS-U6033. They sound very good. I had to trim 3/8 of an inch so they would fit my cabinets. You cannot go wrong as they produce a fine bass response. My only complaint is no mounting screws were included with the speakers. Still a 5 star item.

How many

The price for this DC300-8 12" speaker, is it for one speaker or a pair?
Asked by: Cigarjohn
This item is sold individually, not in pairs.

What is causing the very loud buzzing sound coming form my dc300-8. I have yet to push these speakers very hard. The other one i ordered works well.

Asked by: acmeece
Dayton Audio speakers are covered by a 5-year warranty against material and manufacturing defects. If you believe you've received a defective unit, I'd suggest giving us a call at 1-800-338-0531 so we can arrange for a replacement.

Sealed Or Ported??

I'm looking into a replacement woofer for an old ported box, i was told that a low Qts would work well with a ported box, is this correct? If it is, would anyone recommend this driver?
Asked by: BigWayne
Based on the measured specs of my pair of DC300, the optimal box is about 4cuft tuned to 24.5Hz. That should produce a flat anechoic response to a -3dB point of 25Hz. Use no smaller than a 3" round port, suggest using a flared port and lining walls with acoustic foam.

dimensions screw hole to screw hole?

Asked by: fordtec03
The dimension from hole to hole around the perimeter of the Dayton Audio DC300-8 are not listed. However the dimension across the diameter (12 oclock to 6 oclock) is 291.5 mm. There are 8 evenly spaced mounting holes.This a standard speaker and performs best between 25hz. and 2.5khz.

Good replacement for a 3 cu. ft tower?

20yr. old home built towers need new 12'' woofers; 3 cu. ft., 3walls 'n bottom lined with acoustic foam. Thinking I can add a port and tune to around 30hz. Does that sound about right?
Asked by: mr.mark
That sounds like a good plan, there will be no problem tuning that voume to 30 Hz.

can   i use this woofer or other woofer, in a diy subwoofer cabinet, and a dayton plate amp ?

Asked by: webbfeet65
Yes there are hundreds of options for this application. This particular woofer is better suited for a 3-way cabinet and not very well suited for subwoofer duty, although we do have a Dayton Classic 12" subwoofer that would work better. You can see it below.http://www.parts-express.com/dayton-audio-dcs305-4-12-classic-subwoofer-4-ohm--295-204
