Rated 4 out of 5 by from Perfict for a DJ !I build speaker cabinets & a customer asked me to build a 2 way cabinet using this woofer in ea. of the 2 units, I was totally surprised by the depth & roll off bass they produced at 200 watts !I strongly recommend these speakers !!

Rated 4 out of 5 by from OEM Replacement4 out 5 stars for longevity. Purchased this 15-inch sub-woofer driver as a replacement for my DSUBK-15 15" Powered Subwoofer Kit (Part Number: 300-770) with help from customer service dept. The original driver gave me 5 years of faithful service in my basement home theater. Checked for DOA quality with a sine sweep - passed.. Replacement was a breeze. Gave it a break-in warm-up period by watching the pod race scenes of SW episode I on Blu-Ray. Sounds great. Thanks for the help, Chris.

Rated 5 out of 5 by from Well designed good sounding subwooferThis was bought to populate a Dayton Audio SWC15 sub cabinet.When properly dampened in this cabinet this speaker does a remarkably good job of producing nice tight bass.

Rated 5 out of 5 by from Tremendous Value And Terrific SoundDecided to take a flier on a pair of these when I saw them on sale, for use in an isobarik configuration in a 1.7 cubic foot sealed enclosure. I wanted a “big box” woofer because I find that big box subs sound better than their smaller counterparts, even when the specs “line up” on both. This woofer far exceeded my expectations, and replaced my favorite sub of 8 years in an Acura MDX. Deep bass, plenty of output, with the added definition an iso provides. Many in the car audio industry sneer at the use of isobarik subs, claiming “no sonic benefit, the added expense of the second woofer, and the reduced efficiency of an isobarik, especially in a sealed enclosure”. With regard to efficiency, watts are cheap, plentiful and now come in small packages with the rise of the Class D amplifier. The JL Audio HD900/5 powering this sub can get louder than you'd ever desire, shaking the entire vehicle, so efficiency is a moot point. There is indeed sonic benefit, and not just for “golden eared tweaks” as one high end car audio company claims. The bass is more defined and potent, especially with large subs like a 15 incher. For me, the added expense of the second woofer is well worth it, especially at the price the 295-470 is being offered for! Yes, using each woofer individually in it's own chamber would provide more output, but seriously folks, who NEEDS two 15” subs in a car or medium sized SUV? Headbangers that care more about how it sounds outside the vehicle than inside, perhaps.This isobarik sub has a Qtc of .926 in a 1.7 cubic foot enclosure with an F3 of 34.77. If you prefer a more “whompy” sound, a 1.5 enclosure has a Qtc of 1.076 and F3 of 35.55 Hz, and a 1 cubic foot enclosure would provide max boom while providing a still very respectable F3 of 38.29 Hz. You can't lose no matter which one you choose!Pros: Price, sound quality.Cons: No binding posts! Stepping up to the slightly more pricey but similar 295-206 would be the answer.

Rated 2 out of 5 by from Two defective subs in a rowI ordered this based on all the positive reviews. The first sub had a loose magnet structure, I replaced it and got another one with the same exact issue. I could only hear the vibration from the loose magnet when running frequency sweeps between 60 and 90 hertz. When listening to movies and music it was very hard to hear the defect. Parts express was great and offered to test a third before sending it to me but I decided to go with the higher quality reference HF 15” instead and am glad I did. This sub does play very low but is of extremely poor quality. If you buy one run a sweep before keeping it or have parts-express test it before they ship it to you.

Dayton Audio DCS380-4 15" Classic Subwoofer 4 Ohm

2 of these will be for ht use. I have a recessed area 48 inches off the floor for a projection TV that was there, planning to seal the 15 s in there ported seeming how I have the space for it. Good tuning frequency also?

Asked by: dfran
If you can get away with that volume, a single 6" diameter port that is 4" long will tune the box to 17 Hz. Keep an eye on woofer excursion at higher volume levels, they will run out of gas pretty quick in that volume.

Good size box for 2 of these together?ported

Asked by: dfran
The recommended ported box for a pair of these will be about 26 cubic feet. They will work in a smaller box, but knowing the application will help determine which would be best.

Hi guys, I have a Velodyne CT150 I picked up for $100. Given it's age I want to replace the woofer. Any ideas if this would work? 

Asked by: K0reanjoe
If there is nothing wrong with the woofer I would not recommend replacing it. the best option for a replacement in that enclosure would actually be the RSS390HO-4. If you were willing to seal up the port the DCS380-4 will work, but I would not recommend leaving it ported.

Recommended AMP? Sorry if it might be a bad question, but only because I don't know...  Do I need all 250 of those watts?  or can I get away with something a little less spendy..   All answers appreciated

Asked by: AUETXEPL
The recommended amp for this woofer is the Dayton SPA250. At minimum I would recommend the Yung SD200.

Excessive Sag for Down-fire?

I have run the numbers for the sag calculation on this sub and it comes up to 5.64%. This is .64% over the recommended 5%. Is this going to be excessive? It is in a 1.8 cu ft sealed box. Can the floor clearance (carpeted floor) be adjusted to compensate? I want to make it down-firing to make it fit the living room decor and keep everyone happy!
Asked by: WyoSteve
I would not be worried about 5.64% and would not hesitate to down fire this woofer. The distance to the floor makes no difference in this case, I would recommend 3-4" minimum.

Enclosure tuning

Thanks mtg90 for the quick reply and helpful response. I have a few more questions before I begin drilling. I used a calculator for port tuning and it said my port for my enclosure (8.26cu ft) and this driver should be at least 6 in diameter. Mtg90 you say that those 2 3" ports would work well, because theyre not at least 6" like that calculator says, will these smaller diameter ports not sound / work well in my enclosure with this driver? What would be the difference in performance? Also please tell me wht will be the difference in performance between my box tuned to 18 or tuned to 31. Thank you for all the help! Mtg90 you seem like you know a lot about this driver with experience in an enclosure my size is there any way I could talk with you on the phone or another way to find the best option for me? Thank you so much!
Asked by: Ando
You could use a single 6" port but I think the dual 4" or dual 3" will work just as well. Those 3" ports have really nice big flares on them and two of them will handle the 15" just fine.Your want your box tuned between 18-22hz, if you move up to a 30hz tuning you'll end up with a large peak at 38hz and it will sound very boomy.I don't think parts express would like me posting my phone number or email as I don't work for them. Your best bet is to start a thread on one of the many forums dedicated to DIY speaker builders like Tech Talk. You should be able to get all the answers you need to finish your enclsoure there.
