Dayton Audio DS315-8 12" Designer Series Woofer Speaker
Dayton Audio DS315-8 12" Designer Series Woofer Speaker is rated 4.8 out of 5 by 10.
Rated 5 out of 5 by from Excellent replacementShopped around for tower speakers to replace my old Cerwin-Vega D5s. Didn't find any I liked AND could afford, so I replaced the woofers in the D5s with these. They sound better than the originals and I saved some bucks.

Rated 5 out of 5 by from Fabulous bass response!I bought these speakers to replace another pair of 12" woofers in the hopes of improving the bass output of my home-built speakers. I have to say that I am not disappointed. The reproduction of low frequencies is in my opinion likely better than any speaker I've ever owned or built. I'm even tempted to turn down the bass control on my amp because the bass is so powerful. Highly recommended.

Rated 5 out of 5 by from SolidI have a pair of early 1990's Infinity Studio Monitor 120's (12"-3Way). They needed new woofers and for the price and power rating, these Dayton's are excellent ! I did have to enlarge the opening (no problem; duct tape, jig saw, and a vacuum cleaner) and they slipped right in. With the speaker grills off, the replacement speakers look like the originals. A great look. Even better, of course, is the sound. They sound Great !! I am very pleased. Great sound, great looks. Value is excellent. Paul

Rated 5 out of 5 by from Excellent replacement woofers.My original Cerwin Vega speakers had four screws and the Daytons have five.I was a little skeptical at first about these replacements,but after I drilled the new holes and screwed them tightly to the cabinets I realized it was worth the time and effort. When I turned on the tuner and slowly cranked up the volume the speakers sounded fantastic. A very crisp bass sound and a different sound from the drums which I never really heard from the original speakers. Like the drums were more audible and not sounding in the background. Hard to describe the difference. Just better sound quality.

Rated 5 out of 5 by from Perfect fit and great soundI purchased 2 of these to replace the 12" 8 ohm drivers on my circa 1990 3-way Optimus 950 speakers , one with a torn surround. The new surrounds were too large so to keep the speakers working, I found these which required the smallest boxes available, checked with Tech support and then ordered them. Great sound, much better than the un-torn original. The magnet ~2X as heavy & self gasket helps also. Cutout data is wrong, however, as my 10.625 cutout took speaker perfectly & unfortunately I had unnecessarily cut ~1/8 " on one speaker to fit their supposed 10.75 drop in cutout requirement.

Dayton Audio DS315-8 12" Designer Series Woofer Speaker

Hi.  Can you recommend a high frequency speaker which would  be a good match for this woofer in a two way system in a sealed box?  Also, what would be an appropriate crossover?  Thanks.

I have a box I will re-work for this speaker. It will be a 3-way system, but the woofer will be the only occupant in a 1.65 cu. ft. box. Would you provide the proper port dimensions> Thanks.

Asked by: denzee300
I would recommend a port that is 3" in diameter and 10" long for a tuning frequency of 31 Hz.

hi, i would like to use this in 3way ported design in a three way.what is the optimum port size and length?how much stuffing inside box?

Asked by: s rao
The recommended box volume for this woofer is 2 cubic feet with a 3" diameter port that is 10" long. This will tune the box to 28 Hz. Fill is typical, cover 3 of the 5 interior walls.

Using the Dayton Audio DS315-8 12" Designer Series Woofer Speaker

Can the Dayton Audio DS315-8 12" Designer Series Woofer Speaker be used in a closed box? If so can an F3 of 30 Hz be obtained?
Asked by: Joe S
This woofer will work in a sealed box as small as 1 cubic foot. According to my modeling program this will create an F3 of 60 Hz which does not consider room gain. With proper room placement and a little EQ to the bottom end you can get 30 Hz with this woofer, however your excursion will be limited with higher volume levels.
