Dayton Audio DS115-8 4" Designer Series Woofer Speaker
Dayton Audio DS115-8 4" Designer Series Woofer Speaker is rated 4.5 out of 5 by 6.
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.

Rated 5 out of 5 by from Great little speakerI bought these to replace my JBL speakers that blew. Although the enclosure was a little larger than the recommended size, they sound pretty good. The only issue I had was that the Dayton mounting size was smaller than the JBL so I had to get creative and cut the basket from the old speakers and use it to clamp the Daytons in place.

Rated 5 out of 5 by from Significant UpgradeI bought this woofer as an upgrade to an inexpensive Logitech 2.1 computer speaker system I've owned for several years. Despite the system's price point and compromises that follow suite, I've never been happy with the subwoof. It is a ported box and always produced very boxy and 'woofy' tone. I recently decided to tweek it a bit so I tried various degrees of port blocking, internal dampening, etc. attempting to get this thing more pure and transparent. I've always been a fan of sealed enclosures for just that reason as I always find ports add too much "flavor" for my taste. When it comes to woofers, I don't want to hear the box I just want to move air. After running out of combos and not yet satisfied, I decided to upgrade the woofer. Having been a long time customer of Parts Express, I naturally looked here for a solution. I liked the specs and price point of the DS115-8 and decided to give it a try. Running the specs, the Logitech box is pretty far from the recommended volume/port recommendations but I thought it was worth a try anyways. It couldn't be any worse than the very obviously cheap OEM woof that was in there. At the very least, I would be gaining VC size, excursion and control via magnet size. The install was straight forward and trouble free. Initial impressions were increased bass response and more solid, potent lows for sure. Taking it a step further I decided to use the sound card's EQ and check/flatten things a bit w/my SPL meter and signal generator. After a bit of futzing... BAM! this thing sounds great. I had some definite peaks and valleys to deal with but now my cheap-o 2.1 computer speaker system sounds great!! Bass is full and solid while relatively colorless and a huge improvement over the OEM driver. This little 4" woof rocks. It has great excursion and really moves some air for its size. Definitely took this meager setup from a 4 to a 7 or so. Despite the box being overly large and port not comforming to WinISD's recommendations, I couldn't be happier with the results. Great, cost effective upgrade and two-thumbs up. With a proper box, I'm sure it would sound even better.

Rated 5 out of 5 by from That much bass shouldn't be coming from a 4 inch!I used the 'golden ratio' for the vented cabinet. If you port the driver properly you can get the capabilities of an 8 or a 10 inch driver out of this little 4 inch. Also it's a solidly constructed driver, from the frame to the terminals.

Dayton Audio DS115-8 4" Designer Series Woofer Speaker

What size port should I use with this speaker?

Asked by: Grampa
In a 0.25 cubic foot enclosure, a 1-1/2" diameter, 4" long port will be perfect.
Answered by: MattP
Date published: 2013-01-10

Thanks for the response.Now I need to know what tweeter would go with it and what should the crossover be at?

Asked by: Grampa
Hi! I would recommend something like this if you have smaller space to work with. It will probably be more sensitive or louder per each watt input. So you can try a Zobel network for impedance matching. Or if that's too technical, simply wire a 12 watt Mills non-inductance resisitor on the positive side going from inside the box to the tweeter (or after the crossover to the tweeter). I hope this helps you!http://www.parts-express.com/pe/showdetl.cfm?partnumber=275-040The Vifa's also have a nice quality sound if you want to try those. Again, they may be more sensitive in (db) than your woofer! Depending on your crossover slope ex. 3/6/12/24 db or what they call 1st, 2nd, 3rd, 4th Order. I prefer Linkwitz-Riley alignments :)

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.

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.

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.

I am confused on the vented box calcs. Specs show a vented volume of 0.09 ft³ at 70hz. The vented cabinet description states, "Type: Bass reflex; Size (internal) including volume displaced by driver and port: 0.12 ft³." What is the difference in these?
