Dayton Audio DCS385-4 15" Classic Subwoofer 4 Ohm
Dayton Audio DCS385-4 15" Classic Subwoofer 4 Ohm is rated 4.8571 out of 5 by 7.
Rated 5 out of 5 by from Good, Solid SubwooferThis subwoofer is all it's cracked up to be.At 15" diameter and 4 ohms impedance, itshould deliver the low end and it does.Following the suggested closed-box enclosureoption, I put one in a 19" x 19" x 11.5" ODcabinet with an old #300-792 150-watt ampand it makes an impressive presence in mymodest-sized living room while filling outthe bottom in the sound system. (See pics.)

Rated 5 out of 5 by from Fourth order boom box and infinite baffle applicationsI found myself with enough room to build whatever works best regardless of how big the cabinet may end up being. So after running the numbers through a sim program, I found that a 12.5 cu.ft. ported cabinet (per sub) showed the best results giving a fairly flat response from 15Hz out to 100Hz or so. I used an easy to build design.... 24" tall, 24" wide, and 48" deep. Mounted the sub on the 24" x 24" (front plate) along with a slot port measuring.... 22.5" wide, 2.5" tall, and some 40" deep. Tuned slightly below the already low 19Hz Fs of the driver. Each sub is fed from a 400WRMS (per channel) amplifier giving a little extra head room, but has more than enough power to hurt the subs so be careful............ using that type of power arrangement needs a light touch so to speak. Also I must add that this setup is capable of playing a lot of sub-sonic material in your music and should be used in conjunction with a sub-sonic filter set at about 15Hz or so. Without it the subs can waste a lot of energy and time trying to produce notes that, not only you can't hear, but can damage the subs or at least degrade their performance substantially. That being said the finished product can keep up with the more expensive brands.... provided you have the space for such a large cabinet or two in my case. An amp with a high dampening rate is crucial to control those big loose subs, keeping the attack and decay sharp and accurate. With all of that in place the subs are very musical with the capability to mimic an SPL car driving by your house. Also it should be noted that similar results can be obtained from a well executed Infinite Baffle setup, I say similar because a ported enclosure offers more control over tuning, and a well braced enclosure of this type offers a plethora of other performance enhancing benefits.

Rated 5 out of 5 by from Good Bass for CheapI have used this subwoofer for about three months now, in a 5.7 cu ft box (50% stuffed) and powered by a Dayton SA240-B amp crossed @ 70hz. The sound quality and transient response are excellent; it really brings out the kick drum and reproduces synth bass in dance/hip-hop that is inaudible on the 10" main woofers. At normal listening levels, I get useful output down to 25hz. At moderate levels, it shakes the whole house. At high levels (amp up over halfway with rap music, all the way with rock), cone breakup becomes audible. The steel frame is nice and sturdy. Definitely a good buy for $100.

Rated 5 out of 5 by from Pure AmazementSo i bought this mostly because it was cheap and the power was close to the amp that I had for it. WOW what a subwoofer im only giving it 240 watts and this thing is amazing. The pictures make it look small and the magnet small and almost powerless but this speaker rocks. I had my windows vibrating at 50% its so powerful it hurts to listen to it at full volume. The speaker itself also looks nice the cone has a cool texture to it has great connectors, there is no need to worry about the connections holding. This subwoofer went way over my expectation and I am so happy and for the price of it you cant go wrong. And they quality is so clean and crisp. LOVE IT

Rated 5 out of 5 by from Holy subwoofer batman....Coupled this with a 240W dayton amp and a 10000 in^3 box- this thing shakes every door, window, and piece of furniture in the house! Great sub at an incredible price!

Rated 5 out of 5 by from This subwoofer is great!I just got this subwoofer, and let me tell you... Holy (beep) the sound quality is awesome and the spl is intense. For $100 you cant go wrong :D

Dayton Audio DCS385-4 15" Classic Subwoofer 4 Ohm

I purchased 2 of what I believe to be this 'classic' subwoofer, some 15 years or so ago. One is still functioning. The other just recently blew. I'd like to know if the voice coil / basket assembly can be repaired? Please let me know. Thanx.

How well would this enclosure work for this driver?

I just built a 8.26 cu ft box specifically for this subs younger brother and it turns out I made a mistake in my calculations for enclosure volume and I'm not sure If I want to add a port quite yet to fix my volume error. How would this driver perform in my 8.26cu ft sealed cab? What do you suggest I do to either my cabinet or which driver would work best in my enclosure as it is now?
Asked by: Ando
If you want to get the most out of this driver in that size box, tune it to about 21 Hz (for example, by adding a couple of 3"dia x 7.5"long ports) and you should be OK. Your volume is not that far from perfect.

What would the internal volume and port size be fo this tuned to 18-20hz. i would like to go with the round port

Asked by: qx56
This woofer really likes a sealed box more than a vented box, however if you are not too worried about volume than 10 cubic feet with a single 4" diameter, 4" long dual flared port will tune it to 20 Hz.

Considering two of these in a 40x40x16" vented coffee table

Basically two mirror image 20x40x16" enclosures (really one with a divider) should net about 6 cuft each. With a 4" precision port at its full length, I'd be going for LLT alignment at between 16-17hz. Any thoughts on this idea?
Asked by: Bobspeed
Always star with the ideal - .6 x 1 x 1.6 on your box - the golden rule... You can vary somewhat - but be in the ballpark. Make sure your volume and port work for the T/S of the driver you select. I think the issue here is the coffee table concept. These were popular about 30 years ago. Of course, subs then weren't as good as they are today - especially with THX's influence. (Save Velodyne and a few very high priced items...) You will not get the best bass possible with a coffee table placement. Bass needs distance to develop. It's all about wavelength. Also, room loading is important. Psychologically you want a sub up front to the left or left center, unless you are using multiples etc... It also effects time domain... So - given that - I suggest against the coffee table. Never mind your favorite beverage will be on the floor more than it is in your hand. Have fun with the project !!

What is a good size sealed enclosure?

Just wondering what size sealed enclosure would make this sub sound best with classic rock. I would like it to be punchy and not boomy.
Asked by: nick913
To achieve a Qtc of .707, a 7.39 cubic foot enclosure would be required. You could get away with 5.5 cubic feet by using polyfil to make the enclosure appear larger to the woofer. For a slightly higher Qtc of .85, a 3.2 box with polyfill would do the trick. Hope this helps.

How well would a pair of these work in ~20cf IB application?

Asked by: Bugaudiophile
While it may (or may not) work reasonably well, I would recommend going with a true infinite baffle driver for an infinite baffle application. This Dayton Classic has a Qts of 0.43, which really isn't high enough to be well-suited for infinite baffle. I've referenced our 15" driver that is optimized for this kind of application below for your convenience.
