Dayton Audio DCS305-4 12" Classic Subwoofer 4 Ohm is rated 4.7778 out of 5 by 18.
Rated 5 out of 5 by from Nice SubInstalled this with a 250 Dayton Audio plate amp in a 3.2 cu ft ported box. Loving it so far.

Rated 5 out of 5 by from Great replacement wooferI picked up a pair of these to replace the 12 inchers in my 26 year old Klipsch Forte IIs (one of them blew after all that time). After researching for over a week I found myself back at parts express buying these. I couldn't be happier. They differed a little from stock in wattage and a few other specs, but they work well with the passive radiator. I may be hearing things but these sound tighter and slightly more dynamic than the originals.

Rated 5 out of 5 by from Great sound!The woofer in my 15 year old Kenwood powered subwoofer finally self destructed. Rather than spend the bucks on an entire new subwoofer, I decided to just replace the speaker. I ordered this speaker as a replacement and it's by far better than the original with a much bigger magnet and a crisper sound.The old Kenwood sounds better now than it did when new.Also, thanks to Parts Direct for their excellent service.

Rated 5 out of 5 by from Dayton Subwoofer...Great replacementI have an old KLH 200 watt subwoofer that I used in my tv audio chain. The original 12" speaker was cutting out and showing signs of deterioration. The Dayton appeared to be an upgrade and a well made replacement. Other than having to slightly enlarge the cabinet fitting, replacement was fairly straight forward. The result is a much tighter and cleaner sounding sub that blends perfectly w/ the system. And the price was great!

Rated 5 out of 5 by from Great speaker, just maybe not in 3-way towerI bought a pair of these as woofer replacements for my DCM KX-12 towers. I needed 4 ohm woofers, and these seemed to have the power handling I needed. I was wondering about the frequency response as a woofer, and unfortunately they didn't have enough range. However, as a subwoofer speaker, these Daytons are very well constructed, nice looking, beefy. I'd not hesitate to put them in an actual subwoofer box, or as a replacement if I needed strictly a sub. The excellent rating is for that part. These are worth the price, and in the towers, the bottom end was tremendous.

Rated 5 out of 5 by from Monolith III Woofer ReplacementAfter installing these woofers a year ago I thought I write this review. I replaced the factory woofers on my Monolith III speakers which were beginning to distort due to the dust cover coming unglued from the cone.I already have a subwoofer set up for movies. For purely musical applications, pop, jazz, classical they are highly recommended. Articulate, powerful, musical, they were able to better bridge the gap between the electrostatic element and woofer frequencies. If you looking for a great woofer replacement, these speakers are what the doctor ordered.

Dayton Audio DCS305-4 12" Classic Subwoofer 4 Ohm

Like Rusticman a year ago, I have a blown speaker in a Paradigm PDR-12.  The inside of the cabinet is 1.6 cu. ft., not 2.  And it has a big piece of cotton batting, 26x10x1.8 inches.  The current speaker is 4 ohms.  Does your answer change?

Asked by: sotall
The volume is a little on the small side but it will still work well. I would still recommend sealing up one port to help lower the tune a bit.

Hi PE, I'm currently busy with building a 2.1 Setup for my living room. I'm thinking about using this driver for my subwoofer, however, I prefer a sealed box but I want to tune it to about 30Hz. How big should my enclosure be? And how much filling?

Asked by: HouyuS
You cannot tune a sealed enclosure. The recommended sealed volume under the product details will provide in room response into the low 30's without a problem. We recommend a half pound of stuffing per cubic foot of volume.

Does this driver come with mounting screws? If yes what size? If no what size do I need? I would like to secure it with hurricane nuts, which ones should I use?

Asked by: ThisJustin
These do not include screws. If you are using hurricane nuts, a #10-32 would work with this driver.

What dimension box would I need for good extension into 20 or 30 Hz range. 2x12 sub with slot port(s). Height of the front mounting board is 17". Would be interested in dimension of a similar 1x12, which would also have a 17" front board.

Asked by: Ibjm
I would recommend an enclosure that measures 17"H x 32"W x 18"D externally with a single slot port that measures 2"W x 15.5"H and is 14"D. This will tune the enclosure to 32 Hz.

Trying to find box size for a 2x12 sub. Must use these drivers. Goal is pretty punchy bass, and hopefully hz in the 20's or 30's. Must keep box height close to the height of the drivers, so ports would ideally be slots on the ends. Thanks.

Asked by: Ibjm
A box that measures 13"H x 31"W x 18"D externally with a single slot port that measures 11.5"H x 2"W x 20"L will tune the box to 31 Hz and provide extension into the 20's.

Im planning to build a box with this driver and the SPA250 Dayton Audio plate amp and how do i tune the box using 2 ports (to match the rest of the system) for an F3 in the 30Hz zone??

Asked by: Speak Freak
I would recommend a 3.8 cubic foot enclosure with two 3" dual flared ports that are 17" long each for a tuning frequency of 24 Hz and an F3 of 24 Hz.
