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 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.

Rated 5 out of 5 by from DAYTON AUDIO RSS315HO-4 12" REFERENCE HO SUBWOOFERUsed the driver in the Drake speaker project. Excellent driver, not overwhelming, tight clear base. This driver and the Dayton Audio SPA1000 plate amplifier make an excellent combination for a sub system. Everyone has their own opinions on base/sub systems. My test is the more you listen to a good system, the better it sounds. This system meets this criteria, very pleased. I cannot see how anyone would not be pleased with the Drake speaker project and components. Excellent, excellent driver, especially for the money.

Rated 5 out of 5 by from Outdoor Subwoofer Application is FlawlessHow do you add dramatic low end bass to an outdoor setting that measures nearly 1 acre in area? Well, you add two of these bad boys and incorporate them into a 1.03 cf sealed enclosure (1 enclosure per sub), and mount them firing down toward the ground under your deck. Then you feed them with a Klipsch KA1000 THX amplifier pushing 1000w per channel RMS @ 4ohms. From the first note, they filled in the missing frequencies that even the best Klipsch outdoor speakers could not reproduce. They sounded well balanced and smooth. They play very clean, and very loudly. Once we went into full "night-club" mode, these beauties performed like The Black Eyed Peas were playing live in my back yard. They sounded equally clean pushing guitar notes from Billy Squier, Bass Drums from Metallica, and the smooth melodic beats of Eminem and Kanye West. Doesn't matter what you listen to, or the volume level you play them at, these subs hit the mark... and then some. Just remember to build waterproof enclosures for outdoor applications. A+

.33 seems really small for this, but I plan on using it in my small hatchback. I have .50 cuft available in the predetermined location. An old Orion with 400 watts will push it. Will this work ?

Asked by: fireredv8
Yes this will work fine in a larger enclosure.

I'm considering trying this sub with a rms 600watt  @ 4 ohm amp and an enclosure about 0.7  cubic feet. My question: is this enough power for this rms 700 watt sub and will it make my amp overheat? 

Asked by: Bmoz
That will be plenty of power in that volume. The woofer will not cause the amp to overheat, it does not draw power from the amp. The amp will only overheat if the impedance load is lower than it is rated for, if it is ran hard for extended periods of time, or if it is defective in some way.

Would a 1.25 cu.ft. slotted port enclosure tuned to 33hz work well for this sub in an SUV for SQ or would a small sealed sound better?

Asked by: Worc1
That volume and tune will provide a little more output at lower frequencies. Sealed is generally regarded as "better sounding" so it depends on the sound you are going after.

Will these work in a bandpass and if so what would be the box specs. To run at 30-35hz

Asked by: FTL music
Unfortunately this driver is not well suited for a bandpass box. I would recommend a standard sealed or vented enclosure for this, around 0.5-0.75 sealed and about 1.5 vented, tuned to about 30 Hz.

Looking for a pre-fabricated ported dual 12" box for two of these woofers. Any recommendations for a good size and tuning to look into for these woofers in a car?

Asked by: countvalidus
I would recommend something around 3 cubic feet for both with a tuning frequency between 32-35 Hz. The only option we have is a dual 12" Goldwood box which is tuned to about 41 Hz, so port modifications would be recommended.http://www.parts-express.com/goldwood-e-12d-12-dual-vented-box-speaker-cabinet--260-634
