Dayton Audio DS115-8 4" Designer Series Woofer Speaker
Dayton Audio DS115-8 4" Designer Series Woofer Speaker is rated 4.6667 out of 5 by 9.
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.

Rated 5 out of 5 by from Perfect for a cabinet restoration I just didI have been combing the strangest places people sell used stuff with one thing in mind: well made, floor standing speaker cabinets from the 70's and early 80's. I have found solid wood, made in the USA construction, almost non-existent wear and tear but either rotten or disintegrated speakers. I have been refurbishing these old gems and found this Dayton 4" midwoofer to be perfect for my last application. The pair of cabinets needed all three speakers replaced so I used this 4" for the midrange and it's simply beautiful. It fits perfectly with some 12" woofers I had in boxes and the Phenolic Ring Tweeter 8 Ohm (270-252).I actually received one of these 4" Daytons that looked like it was damaged in shipping- but no worries! Parts Express customer service ook care of me, post haste!

Rated 4 out of 5 by from Dayton 4" DriverGot this to replace a burnt similar unit in a couple of Kustom personal powered monitors. Have heard a little flutter in it from time to time, but overall it seems to be performing well. I may be taxing it a bit in this application, but so far it seems to be holding up.

Dayton Audio DS115-8 4" Designer Series Woofer Speaker

Hello, I'm replacing the woofers from my JBL 2500 bookshelf speakers. Would the ds115-84 fit in the boxes as a direct replacement ? .Joe

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.

Sound Damping material and amount

"With 3/4" material I would recommend external dimensions of 10" H x 5.5" W x 6.5" D with a port that is 0.25" H and 4" W x 6" long. This will tune the enclosure to 70 Hz and give you an F3 also of 70 Hz."In regards to your earlier reply for the enclosure dimensions, how much sound damping material should I use to remove echo and still keep the bass. I already have Acoustic Foam. Should I take into account the volume taken up by the amount of foam used and increase the enclosure size accordingly?Thank you.
Asked by: Chin
In an enclosure that size you don't really need the foam, I would recommend two or three handfuls of stuffing. This is something you can play with until you get the sound you're after.

SPL enclosure advice?

I would like to build a speaker with L shaped vent instead of normal circular port using the Dayton 4" woofer, Phenolic ring tweeter and Dayton Audio XO2W-4.5K 2-Way Crossover 4,500 Hz. Could you please advise me on the dimensions for the SPL enclosure.Thanks in advance.
Asked by: Chin
With 3/4" material I would recommend external dimensions of 10" H x 5.5" W x 6.5" D with a port that is 0.25" H and 4" W x 6" long. This will tune the enclosure to 70 Hz and give you an F3 also of 70 Hz.
