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 4.4722 out of 5 by 72.
Rated 5 out of 5 by from An excellent performerI have been very pleased with the performance of all of the Dayton Audio drivers that I have purchased. I bought two of these to replace the 12" drivers in my Lowrey theatre organ. They perform exactly as the originals did. I am considering purchasing two more to upgrade some Sansui speaker cabinets I have.

Rated 5 out of 5 by from Terrific sound!These speakers replaced 12 inch woofers built into tower cabinet speakers my wife & I purchased in January, 1984 (a funny story goes along with this, but I'll skip it). Over the years the original speakers deteriorated to the point of disintegration.I found these replacements on-line at your site. They sound GREAT!A warning to the mechanically challenged - although these 12 inch woofers replaced the original 12 inch woofers, you need to be prepared to do some minor modification work on the cabinetry as these may not fit as an exact "drop in" installation. Once they are in place, however, crank it up and enjoy!!

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!

Dayton Audio DC300-8 12" Classic Woofer

Can I use 2 of these 8 ohm in parallel to replace a 4 ohm speaker on my Cerwin Vega T-12 using the original crossover with no alteration?

Asked by: CuckoJR
Aside from the obvious cabinet modifications, adding a second driver in parallel will boost the sensitivity up 6 dB from a single woofer. Depending on the actual sensitivity of the original driver, two may overpower the mid and tweeter in the cabinet.

I want to use this in a 3-way system - mid and hi in their own sealed compartment.  What would the recommended port volume be for a vented enclosure?

Asked by: NewB
Using the recommended vented volume that is online, A port that is 3" in diameter and 4-3/4" long will tune the box to 23 Hz.

What is recommended band pass subwoofer configuration tuned at around 40-50 hz for this woofer? (volume of each chamber and the port dimensions) 

Asked by: markpen883
I would recommend chamber 1 being 1.8 cubic feet and chamber two being 1.4 cubic feet. Chamber 1 will need a 4" diameter port that is 6.5" long for a tuning frequency of 48 Hz.

Is this the same driver that's in the Dayton Sub 1200?

Asked by: Jimbo85281
Unfortunately no, we do not sell those drivers separately.

I have jansson 4400 studio monitors I want to replace the 12" woofers. What do you suggest . Mind you I play my music Loud .

Asked by: Teddy202

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
