Dayton Audio DS115-8 4" Designer Series Woofer Speaker
Dayton Audio DS115-8 4" Designer Series Woofer Speaker is rated 4.8125 out of 5 by 16.
Rated 5 out of 5 by from great little woofer for the priceHi fans, I put a pair of these in my self-designed-1/4 wave labyrinths, the length was optimized for ~50Hz. I tested these woofers (as new) as having a higher Fs than advertised: 65 Hz, but that may decrease once they're broken in, and match the labyrinth length more closely. Anyway they are performing great in these enclosures, especially since they are priced so low. Their upper range response is quite good, too, I crossed them over to some horns @ 9500Hz.

Rated 5 out of 5 by from Impressive! direct replacement for SP-BS22LRI received a pair of Pioneer SP-BS22LR bookshelf speakers with broken rubber surrounds for the woofers. After looking around on pe for a replacement, I found these and they are exactly the same except these woofers have improved the magnet support legs with a concave shape versus a flat leg that could bend.I have always made the (wrong) assumption that woofers smaller than 6" will not have any low end. I was wrong... these woofers along with the proper enclosure and port will have no problem going down to 50-40Hz.The price point is also great and helped me inexpensively bring those awesome speakers back to life.Thanks PE!

Rated 5 out of 5 by from Great quality for priceI used these a Bluetooth speaker that I made. I have 2 of these in it. I am running them off a cheap Bluetooth amp bought from ebay. They are on a 2 way crossover crossed at 4500hz. I quality on these are great. Haven't had a single problem with them. The bass response isn't great but not bad for a 4" speaker. It is what I expected.Pros: Quality, Price, Size, Hz rangeCons: None

Rated 5 out of 5 by from Unbelievable sound quality...I put two in one box... separate chambers. I use them as my front main speakers for now while I'm building the sub. My friends keep looking for a sub-woofer. They think I have a 12" sub-woofer hidden somewhere in the wall unit. I can't believe I'm getting that amount of bass from 4" woofers.I built these speaker for my home work shop... after listening to the sound quality, I decided to swap them with the MartinLogan 6 1/2 bookshelf speakers in the family room. Now I have a pair of $1249.98 speakers in my workshop and a pair of home made speakers in my family room. They sure don't look as good as the MartinLogan speakers, but who cares... they are inside of the wall unit.I have to say that they cannot handle as much power as the ML speakers... but overall I'm very impressed and satisfied. Will build a sub soon so that I can reduce the amount of bass going to my main units.

Rated 5 out of 5 by from recommendI bought this to replace the midrange in my 1970 speaker. -works very well...good buy for the $amt. To get a better sounding midrange, you'd have to spend a great deal more. -Brett

Rated 5 out of 5 by from Great for 20 bucks.I made a small pair of computer speakers with these with some old vifa XT25 neo tweeters that I had from a previous project. Crossed over at 3k.The cone and surround look they belong on a driver costing twice as much.They sound great and appear very high quality.Charge a few more dollars more to throw in a cast frame and you'll have an amazing driver.

I'm looking to put two of these in 0.106 cu. Ft. sealed enclosure. Will this config work?

Asked by: Aaseymour
It is a little larger than normal for this application, but it will certainly work as long as you are not lookign for a lot of low end.

 I am planning to build up a 2.1 portable speakers with the dimension of 12 x 6 x 5.5 inch with 2 peerles 3.5 inch PR system driven by this amplifier # 320-608. Would this works well as a woofer for the given system? Thank you very much.

Asked by: Hmeenoi
Yes this will work well for that application.

4 of these in .45 cubic feet, with dayton 10" passive radiator? Powering with tda7492 2x25w, weight added for low f3? Will BC25SC06 x'ed at 6db/oct 6700hz and these running full range sound good? Or 2nd order ~3000hz be much better? Thank you, Daniel

Asked by: asdfghjkl
Four of these will work well in that volume without any weight added to the passive. The tuning frequency will be about 60 Hz which is as low as you can really expect from these woofers. You will have to experiment with different crossover types, but my personal opinion would be to use a second order at 3,500 for these.

I was thinking of using two of these in parallel for a center channel speaker. according to the spec sheet a .09 cu ft vented box is suggested for one driver, so I plan to build a .18 cu ft for the two woofers. What would you recommend for a port?

Asked by: keithym53
I would recommend one of 260-472 cut to 3-1/2" long for a tuning frequency of 55 Hz.
