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 together in this package.

Dayton Audio RSS315HO-4 12" Reference HO Subwoofer 4 Ohm is rated 4.8214 out of 5 by 28.
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.

The box for the sub is about .80cubic feet and given the sub only 600watt and it wants More Power! ....... The build quality is solid cast aluminum very very heavy magnet......Sorry... my English is my second langue....

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+

Rated 5 out of 5 by from Hits the lows great!I had a 12 inch infinity subwoofer with a rear port in a fairly big enclosure. I bought a 500 watt bash amp & as I expected the stock speaker couldn't take the power and finally blew out.For a $130 this speaker is the best bang for the buck. Finally putting the bash amp to work and this pair absolutely shakes the whole house and will hit every low frequency.Enjoying my 7.1 setup more than ever!

what is yhe smallest enclosure this sub will perform in?

got a trunk box 20*20*6. Just built it in spare tire area...Would this woofer do well in a box that small with polifill? the current 12inch powerbass does the job but i want something more high end...
Asked by: brauhmaudio
You don't state the wall thickness, or whether your stated measurements are OD or ID, but assuming it's OD, and your wall thickness is 3/4", that gives you about .9cubic feet, which is just about perfect for this driver, which likes a box in the .6-1.0 cubic foot range. Loosely stuff it with Polyfill (sealed box please!), and it should perform excellently.

HO vs. HF

I need some help choosing between the HF or HO. I have a 2010 Chevy Crewcab and want to run dual 12's under the rear seats. I'm having trouble picking between the HO and HF. The HO runs 700 watts RMS and has a xmax of 12.3mm and the HF runs 400 watts RMS with an Xmax of 14.3mm. I'm confused, I was assuming the HO would push more air and be the "louder" of the two? Also, do you recommend ported or sealed and what do you think the min cubic feet would be with each. Thanks
Asked by: PaRider380
I'd go with a sealed box and the HO is better sealed. The HF has a thinner cone and is reported to "oil can" (flex) in a high power sealed alignment. HF is great vented though, but much larger cab. Look at The Drake: http://www.parts-express.com/projectshowcase/projectindex.cfm using the same driver. I have two drakes. I'd use it in a .9-1.1 ft3 sealed cabinet with lots of power. In home use it needs some eq at 30hz. In a car, you will get plenty of gain to compensate for the small enclosure.

Are these drivers usable in a bass Horn ? If it's the case, what sort of Horn will do the job ? An example using 2 drivers in each horn ?

Can such horns deliver more than 100 dB SPL up to 200 Hz ?
Asked by: ondesx
I would not recommend this driver for a horn design. A great contender would be the Eminence Lab 12. There are many designs that involve this woofer around the net, I would recommend a Google search for some great ideas for a horn. Unfortunately we have no way of modeling one.

Cabinet Size for 4 of these

I have two questions what size cabinet would I need for four of these in a sealed cabinet that would be suited for both music and movies and two how would the sound of the subwoofer mesh with a pair of Polk Monitor70's?
Asked by: Jarad
Sealed cabinet with a Qcb of .7 (optimally flat), 2.465cu.ft., approx. .6cu.ft. per driver, as stated in the other answer.For a Qcb of .6, which to my ears sounds better, and has a slower low end roll-off, 4.135cu.ft., approx. 1cu.ft. per driver.Anything between 2.4-4cu.ft. would perform just fine.Get your phase and levels matched, and it should match up with your Polks with no problems.I must point out it is unlikely you need four to do the job, two would be more than enough, and the HF version of this woofer, while needing a somewhat larger box, would extend further into the low bass. The HF is the sub I use, and I could ask for none better. I have one placed in a 3.3cu.ft. vented box, powered by a BASH300 sub amp, and it rattles the walls. F3 is around the 20Hz mark in my room.

ht sub

I wanna build a box with this sub and a 500 watt amp and wanna use it for movies and music and play down into the 20's ported or sealed.
Asked by: frankr
To the right of the product is a specification sheet. On that are all the thiele/small parameters you will need to plug into a box calculator. You can find many on the internet for free. You can then look at various alignments for ported or sealed. For the most accurate bass - go with a total Qts of .707. This driver will most likely deliver the best bass performance with a ported enclosure. Don't expect anechoic response much below 26hz as this will be an impedance peak. However, real world, in room performance should be flat to about that point if properly designed. Keep in mind while this sub will go low - loudness is another factor. A single 12" is fine for a small room. For a larger room, 2 would be in order. Small being in the order of 12 x 15 with an 8 foot ceiling... larger being 16 x 20 with a 9 or 1o foot ceiling... Low bass is great - but you also want to move a lot of air - and the structure of the walls and placement effect the performance. And concrete floors make for more accurate bass - but wood floors interact and can make sound effects such as explosions more involving... Goof luck with your project.

Down-firing distance?

I am considering buying one of these drivers to use in a custom-built subwoofer enclosure. The reason for the custom enclosure is that I want to build a low-height cabinet so that I can "hide" it under another piece of furniture. There is enough space to make an enclosure with an internal volume of 1.70 cubic feet. But I only have 8" of vertical height to work with, and by the time I add up 3/4" for the top of the cabinet, the mounting depth of the subfoofer (plus some small amount of clearance between the rear of the driver and the inside of the cabinet top), I only have about an 1-1/2" between the face of the woofer (mounting flange) and the floor (hardwood floor by the way). Is that enough distance, or will the air moved by the woofer bounce back from the floor and interfere with the cone movement? Is there any rule of thumb to use when determining how close to a floor or wall or other surface a woofer can be positioned? I could use multiple 8" subwoofers, for example, that have a shallower mounting depth, thereby allowing for a bigger vertical distance between the woofers and the floor, but I would still be wondering how much space is enough?
Asked by: Lane
There is no rule of thumb for this, however 1-1/2" may be pushing it. I would recommend about 1/4 the driver diameter, in this case no less than 3-4". You may be farther ahead using multiple smaller woofers to achieve good results.
