Dayton Audio DCS385-4 15" Classic Subwoofer 4 Ohm
Dayton Audio DCS385-4 15" Classic Subwoofer 4 Ohm is rated 4.7778 out of 5 by 9.
Rated 5 out of 5 by from 18 year old replacement subthis was a replacement driver for my 18 year old Sonance subwoofer, only had to make a minor adjustment to the internal bracing ( 1/2 inch of a 4 inch rib )for the additional depth. Everything else was a perfect match, diameter cutouts and bolt patterns were like factory (Sonance ) specs. Sounds like it did 18 tears ago, lovin it!

Rated 4 out of 5 by from Good ValueSounds good in my 4 cubic foot acoustic labyrinth but Would probably do better in a larger cabinet.

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

Building 3.8 ft3 sealed, which amp would work best boost or no boost? 90% used for movies!

Asked by: 67mustang
I would recommend either the Dayton SPA250 or Yung SD300-6 for this, both with boost.

Will this work well in your SWC-15?

Asked by: lastbutnotleast
The rabbit cut will need to be enlarged in order for this woofer to fit properly, but it will work well in terms of volume.
Answered by: MattP
Date published: 2015-07-06

So, the recommended box volume is 3.83 ft.³ and the compliance volume is 10.98 ft.³ Would I be correct in assuming that if I made the volume closer to the compliance volume the F3 would get closer to the drivers FS? What other effects would there be?

Asked by: Lapierre
In this case yes, the larger volume will drop tuning and F3. If you want the most bottom end possible from this driver, a 10.5 cubic foot enclosure with two 4" diameter, 17" long dual flared ports will tune it to 18 Hz and have an F3 of 17 Hz.

I'm thinking about building an Isobaric with a pair of these (size concerns) but I could use advice on the enclosure. I'm thinking a downfiring clamshell slot ported...but I'm getting mixed calc results. Thoughts?

Asked by: WontLetMeReuseMyName
I'm getting a modeled volume of 6.8 cubic feet with a slot port that measures 1.5"H x 12"W x 20"L for a tuning frequency of 18 Hz.

I'm interested in pairing this with the dayton 250w plate amp.  Can you tell me what the optimal size would be for a sealed box in order to get a Qtc of .707 and the Fs down to 35hz where the bass boost of the amp kicks in?

Asked by: Aruss
The recommended sealed box for this woofer for a Qtc of .707 is 3.8 cubic feet.

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.

Asked by: Mojoaudioguru
This is a better question for our speaker repair department. Please send them an email with pictures of the woofer for identification, speakerrepair@parts-express.com.
