Product Details

Dayton Audio DCS450-4 18" Classic Subwoofer 4 Ohm

Dayton Audio Classic Series woofers are excellent for use as replacement speakers or for new loudspeaker system design and construction. The DCS450-8 18" subwoofer has developed quite a reputation for having the best bang-for-the-buck performance and value available anywhere. Extended bass response and generous Xmax make this driver ideal for use in high output subwoofers. A Qts of 0.47 allows the DCS450-8 to work well in both sealed and ported speaker enclosures.

A polymer laminate paper cone offers rigidity, while the 3" four-layer 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 DCS450-4 18" Classic Subwoofer 4 Ohm
Dayton Audio DCS450-4 18" Classic Subwoofer 4 Ohm is rated 4.5667 out of 5 by 30.
Rated 5 out of 5 by from Great for home theatreI've had this about a year and couldn't be more pleased. I built this into a 13 cubic foot vented box powered by the Bash 300W amp and the sound is amazing. The only problem is I've been reminded everyday by the wife that this huge black box does not belong in the living room. She'll never understand :)

Rated 5 out of 5 by from THE sub to buyIf you are building and actual home theater (like you are building each speaker and striving for it to sound exactly like the movie theater) then this is the sub for you. I have this sub paired with the Dayton 250 watt amp and with the rest of my system it is just like the movies. I've had a few parties and music sounds good but where this thing shines is ht, I have it in a sealed box that looks just like an end table, complete with fake drawers so if your wife won't let you have something this big just do what I did and make it look like furniture. I could not be more thrilled with it. I have built many sub boxes for home and car audio and this sub is not the loudest I've built but by far the best sounding. In my room, from 20-60hrtz is just as smooth and flat as can be. I love getting on YouTube and looking up the dlp sound intro because this sub has that earth shaking low note at the very end just like at the movies.....5 stars all the way

Rated 4 out of 5 by from Very Happy With PerformanceFirst time building a subwoofer. I read a lot of the reviews and tips on this site (thanks for that). I overbuilt walls and bracing, if that's possible. 7.5 cu ft sealed box. Large room. Had to turn down sub as the furniture started moving watching the opening of Star Trek into Darkness. I have no objective data here, but this sub and the Dayton 250 watt plate amp, have given me a very descent subwoofer system for HT. And at a very low cost.There is a spike at around 40 HZ, so now I guess I will have to look into a notch filter to smooth that out. Thanks again for the comments that helped with this project.I would definitely use this again.

Rated 4 out of 5 by from Good bass for the buckI ordered a set of these woofers for stereo listening of classic rock. I built two 4 cu. ft. sealed cabinets. The sound is solid and fairly deep. Power handling is good and Xmax is good. I am running a Crown XTI 1002 amp and it has plenty of power to shake the walls with ease. ( if you don't have a Crown amp it should be your next purchase, amazing quality, extreme power!!!). I think the subs would play louder and deeper with a vented box, but it would be larger than I want. Overall they are not the best 18" subs I have ever heard, but at $125 each they are a great value. I also have one in my sons car and with 250 clean watts it shakes everything in sight. Great for car audio as its 4 ohm and fairly efficient.

Rated 4 out of 5 by from AWESOME SUB FOR THE PRICEI HAVE BOUGHT 3 OF THESE SUBS, THE LAST PROJECT WAS IN A 22" SEALED BOX WITH THE DAYTON 250 AMP...IT SOUNDED GOOD BUT THE LOWS BELOW 35HZ SOUND A BIT OFF WHEN THE EXCURSION IS A LITTLE OVER HALF WAY. THEY SOUND AMAZING AT LOW TO MODERATE VOLUME AT ALL FREQUENCIES. MY LAST PROJECT WAS A 24" CUBE VENTED BOX TUNED TO 21HZ, IT DID NOT EXIBIT ANY PROBLEMS AT THE LOWER FREQUENCIES AT HIGH VOLUME, SO I WOULD RECOMMEND GOING PORTED IF YOU CAN. EITHER WAY, YOU WON'T GET THIS MUCH SOUND FOR THIS PRICE ANYWHERE ELSE.

Rated 5 out of 5 by from Great sub for Ht!I bought this sub a little over a year ago and I couldn’t be happier with it. Its currently being used in my main floor living area for HT in a 10cf enclosure tuned to 24hz disguised as a sofa table. The output of this sub is incredible and at times a bit much for my smallish living space. I ended up having to tighten/deaden all of the light fixtures in the house as well as add double sided tape to pictures that wouldn’t stay on the wall! I would highly recommend this sub to anyone with the extra space that wants a ton of sound on the cheap.

Dayton Audio DCS450-4 18" Classic Subwoofer 4 Ohm

For car use, given roughly 4.5cu sealed net and 350w on tap, would one or two drivers give the best results?

Asked by: Deiko
One woofer will work best in that volume sealed. Two will allow for more output capability, but with only 350 watts it will not matter either way.

Would this woofer be ideal for horn loading? 

Asked by: cadidady84
Yes, this would be a good option for horn loading.

Would two of these be good for IB sub set up in a manifold?

Asked by: 67mustang
These should work fine in that application, but you will want to watch excursion levels at higher volumes.

What size box and round port would I use to tune box to F3 of 19hz?  Using WinISD beta .44 it says I need a 464 liter box with 1 = 4" port that is 1.574" long. That port can't be right?

Asked by: ChuckB
Bassbox recommends a volume of 14 cubic feet with a 6" diameter port that is 11" long for a tuning frequency of 19 Hz.

I currently have 2 dayton classic 18" in 2 7ft^3 enclosures running stereo in 2 corners of a very large room. It sounds amazing. I only us them for music listening. Can I put 1 more 18" in each enclosure or would that not be enough volume? 2 18s in 7^3?

I already have 2 classic 18 subs and they sound awesome. I would like to upgrade. What would give greater SPL 2 new replacement Dayton reference 18" subwoofers or add 2 more 18' classic subwoofers. I only use 4 ' sealed boxes. I have unlimited power.
