Dayton Audio RSS315HO-4 12" Reference HO Subwoofer 4 Ohm

The Dayton Audio Reference Series subwoofers take the quality and performance of the much acclaimed RS line into the subwoofer realm. As with the rest of the Reference Series, the main focus of these subwoofers is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three short-circuit paths within the motor structure. A durable aramid fiber spider and extensive venting throughout provide quiet and uniform excursion. The black anodized cone, rubber surround, and custom basket give this driver a unique, high-end look. Choose the high output version for automotive applications or for equalized high-power home subwoofers.

A knock-down 1.25 cubic foot subwoofer cabinet built specifically for the RSS315HO-4 is available here. Save 50% off the price of the cabinet when you buy the cabinet and RSS315HO-4 subwoofer (at regular price) together in this package only.

Rated 5 out of 5 by from Build quality.Working perfect. Sounds great as a stereo sub also matched well with the other sub. Will be even better when I build the cabinet this spring.

Rated 5 out of 5 by from ThumperGreat sounding. Plays loud. Made a 1.75ft box with 14.5x1.25x 26" port. More than surprising with Dayton 500watt plate amp

Rated 5 out of 5 by from House Shak'inBuilt my very first sub and it turned out way better then expected. The Yung SD-500 plate amp is set at 3 with reciever setting for sub level set at 3 and this thing shakes it like a "Wild Thing"!!!

Rated 5 out of 5 by from Excellent subwoofer for the moneyI originally purchased one of these to take the place of a blown MK subwoofer. I was so happy with the result I purchased a second. MK subwoofers are always sealed designs, so both of these started as sealed subs in a 2 cubic foot box (each). I enjoyed the sound and fed them appropriate power (one had a 300W bash and the other a 500W bash). After modeling one day, I realized I was leaving some bass on the table, as my F3 in a sealed box was close to 60hz. I quickly drafted plans to port and ended up with a 23" long, 4" diameter port in each box. The sound is simply incredible. My F3 is now about 25hz and the overall sound is so rich and full. I was disappointed with them after awhile in the sealed form, but now after more than a year in ported I still find ways to show them off. I have switched to a pro amp giving each about 550W and they seem to love it. So, in conclusion, I am running them each in a ported MK V75 enclosure tuned to 25hz. They are rich, full and loud. Amazing value, as these are true beasts; you can tell when you see them in person.

Rated 5 out of 5 by from An affordable beast of a subI'm not an audiophile but I pretend to be. In the car I have always stuck to more common brand names for car audio. This sub replaced a 10" Kicker Solo-Baric from the late 90's that actually still worked like a champ but I wanted an upgrade.Right out of the box I was impressed with this sub. It's heavy and well made. The fit and finish are great in my eyes. I don't need flashy so this is perfect. I put it in a sealed 0.82 cu. ft. box. The box is 3/4" MDF and the front baffle is 1.5" thick. I have it powered by an Alpine PDX 1.600 which is run by an Audio Control LC7i. I have the gain all the way down and it kicks! I have played some tones in the high 20Hz range and they are acceptable. It drops off quick below that. The sub is what I wanted, musical, punchy but will still hit those low notes when they're there.If I have one gripe so far it's that the mounting holes are so close to the required cutout that there's not much material to play with. I tried to use some threaded inserts and they were too close to the cutout. I should have made the cutout even tighter.

1 cubic foot box tuned to 32hz to be used in a car. f3, f10, and max spl? also, will 17 square inches of port area be large enough to not present any port noise issues?

Asked by: Tyler99
With that volume and tuning, your F3 is 33 Hz and your F10 is 24 Hz. Maximum SPL with 700 watts is ~115 dB (modeled). That should be enough port area but the length would need to be 37" for a 32 Hz tune.

The frame of this woofer is 9.6mm thick for countersinking.
Answered by: MattP
Date published: 2015-06-15

what size port Is needed for tuning 32Hz in this box: 3/4" MDF Encl. Vol. is 1.25 Cu/ft Height 13" x Length 16" x Top Depth 12" x Bottom Depth 15.5" (slanted box) Im wanna pack it with some pollyfill to bring up the internal Volume to about 1.5 cu/ft.

Asked by: djchino69
In order to achieve that tuning frequency, a minimum diameter of 3" is recommended and a length of 15" is required. A 4" port would be even better, but it would need to be 40" long for the same tuning frequency.

how will this work in a car setup in a 14x14x14 sealed box made of .75 mdf. f3, f10, and max spl with 500 watts?

Asked by: tyler99
In that volume your F3 is 63 Hz, F10 is 31 Hz and maximum modeled SPL with 500 watts is about 113 dB.

The 12 inch version of this sub recommends a .33 cubic foot sealed enclosure. Is this correct? How does it require less air space than the 8 and 10 inch versions?

Asked by: Woofer Pressure
Yes this is correct. The size of the woofer does not directly relate to enclosure volumes, it just so happens that the parameters for this woofer require a small enclosure volume compared to the others.
