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.

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

Would anything about 100hz be a waste of time for this driver, I was really needing some detailed output to 200hz? I notice some potential phase issue about 100, rise db rise above 100 looks tamable with my REW. Thoughts?

Asked by: Fergie04
The Reference series 12" subs have been crossed as high as 500 Hz in active 3 way setups, this should be no issue for this driver. The anomaly you are getting could be cause by a room node depending on measurement conditions.

I'm wanting to build a subwoofer with this driver. I use it for 50% movies and 50% music. Should I go with a sealed or ported box? If I were to go with a ported box, would the 1.00ft (300-7085) knock down box work well? And dimensions for the port itself?

Asked by: CheesyHotDogPuff
This woofer will do very well in a sealed enclosure for these applications. A 1 cubic foot volume will work well sealed or vented, but vented would require a 4" diameter port that is 30" long, so it would probably have to be external.

My aim is to built a subwoofer that produces chest thumping bass. Will this driver works well with two Dayton's 12" passive radiator? If yes, what should my internal box volume be? And what weight is need to have that chest thumping bass for movies? Thank

Asked by: Mike Sim
Chest thumping bass comes from frequencies between 60-100 Hz. I would not recommend using this with the Dayton passives, they do not have enough displacement to handle it. This will give you a punchier sound in a sealed box, so that might be what you are after.

I am considering getting one of these to put in a 1.08 sealed enclosure ( That is about as large as I can go in a single cab truck). Will 500watts at 2ohms suffice for this setup in that box? I am looking for a musically accurate and overall SQ setup. 

Asked by: AdamJosiah
These will work very well in that volume. 500 watts would also be a perfect amount.

What is the volume of this woofer's displacement that will need to be accounted for in box building?

Asked by: agcelica
This woofer displaces 0.135 cubic feet.
