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 4.5128 out of 5 by 78.
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.

Rated 5 out of 5 by from This replacement worked out wellI have been using a 70's era Craig receiver and larger 3 way Craig matching 70's speaker enclosures for a while now. It is used in a personal nightclub at my residence at moderate to sometimes higher dB SPL. This brand was among equipment sold by my father's business back in the day at a TV/Appliance sales and service store. This is where I cut my teeth repairing radios by age 12 and up to the component level repair on color TV by age 14. I have a few decades or so in this type of work.The original 12 inch woofer surrounds finally gave up recently and I chose Parts Express as a likely source for replacements. I purchased a pair of DC300-8 12" instead of fixing the deteriorated surrounds. Upon receiving the new speakers, I removed the originals and those certainly had a fairly low weight magnet structure, as might be expected with a moderate priced 70's product. The new drivers seemed to be fairly priced for what I judged to be a decent design and build.I expected a possible bolt circle alteration to be required, but the new drivers ended up pretty close, and near enough for no modification to the threaded insert locations for the drivers in the original enclosures. I am happy about that result.I did compare the first new one installed to the one old driver that still had enough surround in the other enclosure just to see the difference. Again, I am pleased. The receiver is a true 60 watt continuous per channel discrete bipolar output transistor design. I am not a hi-fi nut but I did notice the new driver had better clarity and enough power handling ability to suit my needs, compared to what I had been hearing previously...I do have extensive experience in live sound and own a substantial sized quality rig for my rock group. Of course these drivers would not be appropriate for that sort of use but I can honestly support these drivers for home club applications similar to mine.

Rated 5 out of 5 by from Sound great!I bought these 12" woofers to update some walnut Silvertone speakers from the 60's and they sound great in those old ported cabinets.Those old Silvertone speakers even have adjustable crossovers that still work.

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!

My infinity cabinet crossover is 800 hz 2nd order out of the 4 ohm woofer. Puting in an 8 ohm dc300 will be @ 400 hz. I am thinking of bypassing the whole woofer leg of the XO. Will a dc300 work if the entire 20-20K hz signal is fed to it.

Asked by: Srinath
It's unlikely that the DC300-8 driver will be damaged by receiving a full range signal, however the sound quality will not be a good match for what the original driver could provide. I recommend investigating the DCS305-4 12" subwoofer; even though it is a subwoofer, it has an extended upper frequency range and a 4-ohm impedance that will likely work well in your original application. Keep in mind that the only way to truly restore your speakers to factory performance is to locate a factory-original replacement woofer from Infinity.

I have a 2.42 cuft sealed Infinity kappa 7 cabinet not subtracting the driver volume. What is the driver volume of the DC300 and will I be able to keep it sealed and get good sound.

Asked by: Srinath
The displacement of this driver is 0.09 cubic feet, so not enough to matter in this case. This will work well in that volume sealed, with an F3 of 50 Hz and in room response into the low 30's. If you wanted, you could install a 3" diameter, 6" long port into the cabinet which will tune the enclosure to 30 Hz and provide a little more extension.

I would like to use these in a 4.90 cu ft enclosure, what should I use for a port size?

Asked by: straycat602
I would recommend a port that is 3" in diameter and 4-3/4" long for a tuning frequency of 23 Hz.

Hi, I am looking to replace the dry-rotted Realistic 12" woofers (#40-1026)in my 20 year old homemade boxes. My boxes are about 2.66 cu.ft with 3 inch ports roughly 4.5" long. Foam installed on 3 sides and bottom. Would these be suitable replacements?

Asked by: Ben Jammin
Yes these will work. Right now the enclosure is tuned to about 33 Hz, you could make the ports 8" long and drop that tuning frequency to about 26 Hz for smoother in room response and more extension.
