Dayton Audio DS115-8 4" Designer Series Woofer Speaker
Dayton Audio DS115-8 4" Designer Series Woofer Speaker is rated 4.7273 out of 5 by 11.
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.

Rated 5 out of 5 by from Great for guitar ampI'm bought one to test in a PVC-pipe guitar amp idea. It's great! I don't think I'll need a tweeter because the highs are good enough with some EQ. Very impressed with the quality/performance.

Rated 5 out of 5 by from Nice little speakerI got this to replace my JBL 2500 woofers .The boxes were a bit large for these speakers so I added more foam to the boxes to match there specs .Now they sound great .

Rated 5 out of 5 by from Great for small speaker projects!These woofers are great for small speaker projects. I am using a cabinet made of 3/8” MDF with ½” baffle. Outside dimensions: 9 ½” by 5 ¾” by 6” deep with an internal volume of .11 cubic feet with acoustic insulation stuffed inside. The port is 1” flared by 5 ¼” set in the rear. The sound of the woofer is beautiful mated with a Dayton ND28F6 1 1/8” fabric dome tweeter with second order crossover at 3500 Hz. By putting them as close to the wall as possible the bass is fantastic. Since they have 4.5mm Xmax, the go down 50 hz easy. I had to do this low tech by just playing test tones, but 45 hz still comes out strong, then they role off fast any lower. So, for most music, I don’t need a subwoofer. The sound is very natural with my type AB amplifier and line conditioner, flat and well blended. I would recommend this woofer for any mini monitors or mini speakers used in a small room.

Rated 5 out of 5 by from Quite a nice surprise!I have a brace of these woofers (twelve total) installed in the Curt Campbell/DIY Sound Group "Fusion-4 Quad4" L/R and Center speakers in my exercise room. Usage is on the order of 90% HT, 10% music; while the speakers do a great job in the music role, they absolutely shine for watching movies- especially on those with dynamic soundtracks with lots going on. Couldn't be happier!

Rated 3 out of 5 by from A good value but better for a few $ moreOverall a nice unit with excellent power handling. Hefty magnet and v/c can go quite loud before becoming unlistenable. T/S params compute very well, confirmed by actual field results with finished speakers and specified air loads. Impedance shows a clean trace. Smooth response allows for simple crossovers .Major caveat is the frame. Basket is shallow and rear hole openings don't really clear if using a baffle greater than 1/4 " . Recommend using a 3/8 " Baltic Birch baffle and countersinking 1/8" d. Round over the back side of the entry hole opening. Sound improvement is substantial over surface mount and thicker baffles.Considering the quality of the cone, magnet and voice coil, charge an extra $5 and make available a cast frame version with better basket windows.

Hi! I am looking to replace my Wharfedale Wh-2 Surround drivers. Will this speaker fit into the existing cut out? The out side edge of the speaker is 4.5". Here is a link to the pdf file http://hcr2lorme.free.fr/fiches/wharfedale_wh_manuel.pdf

If I were to put 4 of these in a sealed enclosure how much internal volume would I need to get down to around 70 to 80 hrtz , looking to build a satellite with a lot of punch . 

Asked by: spunk
A sealed box will not have an F3 that low with this driver regardless of size. With the addition of room gain these will play to 80 Hz using the recommended volume on the product page.

If I was using a cabinet with internal dimensions of 9 x 5.5 x 4.5 what size port should I use?

Asked by: Remy
I would recommend a 1" diameter, 4" long port like the one below. This will tune the box to about 60 Hz.http://www.parts-express.com/speaker-cabinet-port-tube-1-id-x-4-l-flared--260-470

dimensions for a tuning frequency of 50Hz - 60Hz --- also can it be possible with 2 1" x 4" port tubes?

Asked by: speakerfreack
I would recommend .24 cubic feet total, which will be internal dimensions of 11"H x 5"W x 7.5"D with two 1" x 4" ports for a tuning frequency of 57 Hz. I would recommend relatively heavy stuffing in the enclosures.

Suitable as a midrange driver?

I'm trying to find a midrange replacement driver that will fit a 3.75" baffle cutout. This little gut would fit perfectly but will it work well as a mid driver in a 3-way speaker?
Asked by: btntx
Yes, this would work as a midrange woofer--It is a woofer, but it has a useable response up to 8,000Hz--so it will cross over to whatever tweeter you have. Many people prefer the sensitivity of an accordion surround for a midrange speaker though. There is a slight added sensitivity there--but this speaker will take more pounding over time.
