Product Details

Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm

As with the rest of the Dayton Audio Reference Series speakers, 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 for the Reference Series RSS315HF-4 12" subwoofer speaker. The black anodized cone, rubber surround, and custom basket give this driver and the rest of the Reference Series a unique, high-end look. Choose the high fidelity version for home systems when you are looking for clean, low bass and are not restricted by cabinet size.

Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm is rated 4.8125 out of 5 by 64.
Rated 4 out of 5 by from Great performer!There isn't much to say. I am very satisfied with mine in a sealed enclosure. Very clean output, great lows, and quality construction.

Rated 5 out of 5 by from Great HT SubThis sub replaced an old 12" JBL I had in a custom 2+ cu. ft HT enclosure. Terrific quality. The JBL was nicely built, and this one probably weighed in at about 2-3x what it did. I'm using it with the 240W subwoofer plate amp, and am impressed with the performance. Good output, low distortion, no bottoming out.

Rated 5 out of 5 by from Great driverI installed this driver in a 2 cubic foot sealedenclosure. The bass is strong and not boomy. Iam quite satisfied with this driver. I would recommend it to anyone looking for a great quality driver at a reasonable price.
Date published: 2008-06-10
Rated 5 out of 5 by from European build quality and excellent performanceThis driver is built very well with really nothing coming to mind for improvement. Very low distortion and if used in a well braced and damped enclosure with a high quality amp can compete with very expensive commercial subs.

Rated 5 out of 5 by from Outstanding sub!!!Put this sub in a 3.75 cu.ft. mdf box with 2 flared ports. Powered it with a 300 watt bash amp. It has plenty of punch with only 300 watts. this thing goes deep. 3db down 18.4 hz!!!!! I very highly recommend this sub to anyone who doesnt mind a big box.

Rated 1 out of 5 by from so so subFirst of all this is a very nice looking sub but that is the only thing nice about it. The sound is acceptable but not exceptional @300w rms(is a lot). I had build two custome boxes for it recomended by parts express techy. Which are the 12" Titanic MKIII Sealed 12" Titanic MKIII Vented boxes the sub sounds ok but I have to send tons of power to it to here anything. I have tried severals amps including Carver 1.5t, Kenwood M2A, and dayton240w rms 4ohm amp. SPL: 89 dB 2.83 V/1m not good SPL. I am going back to my Infinity 15DVC sub for HT which is hands down the better sub. Also have Dayton bookshelf speakers that consume alot of power too.

Rated 5 out of 5 by from Great WoofersThese are simply the best 12" woofers I have ever heard in a car, period. I put two in my Ford Escape and they are awesome. Quality and volume are more than I expected.
Date published: 2008-04-06
Rated 5 out of 5 by from Phenomenal soundPurchased to replace the tired driver in my JBL D112 Subwoofer. Without knowing anything about driver parameters, I simply substituted this for the original driver. The resulting sound quality is much better with noticeably more low frequency output.
Date published: 2008-04-04
Rated 5 out of 5 by from KSSurpassed my expectations!HT application.4.2 cubic inch with 4" aero port & 300 watts.
Date published: 2008-03-23
Rated 4 out of 5 by from Great buyThis driver reproduces bass with authority. I ve had at least 5 different drivers in my DIY subwoofer enclosure this ones the keeper. Deep, accurate, hard hitting great for HT use. Would recommend to any DIY sub builder, and the price of $119 can NOT be beat.
Date published: 2008-03-20
Rated 5 out of 5 by from Wow!An awesome sub. Truly captures the lowest of lows. It replaces an older Phase Technology subwoofer that had blown, and it made the cab sound 10 times better. That true bass sound.
Date published: 2008-03-15
Rated 5 out of 5 by from This woofer works very clean from 25Hz to ~ 250HzThis woofer is very solid. The suspension is harder than expected, yet the output is very clean. In a mid-size box this driver goes down to ~25Hz. I cross it over at ~250Hz at the top end. It replaces an old 12 inch JBL driver... wow what a difference in clean undistorted low bass. I would not go much higher than 250Hz due to a significant resonance ~ 1600Hz. Use at least 12dB / Oct in the crossover to avoid that frequency. Have I mentioned that Parts Express is great to deal with.... well now I have!
Date published: 2008-02-28
Rated 5 out of 5 by from Very high quality subwooferThis subwoofer handles very low frequencys with ease! Sounds from it are clean, full, and veryaccurate. This speaker is ideal for a driver for a very high end home theater subwoofer system with enough headroom to meet the requirements for even very high volume levels. It also complements music with the bottom end lows that complement higher end main speakers. Great product!

Rated 5 out of 5 by from WOW, I just LOVE that DEEP SMOOTH BASS...I had two old Velodyne cabinets that had 15" Passive Radiators in them and the original drivers had some problems. I decided to try the RS315HF 12" driver because of all the good words I've heard about them. I must say that I now have a much better sounding Sub Woofer than what Velodyne originally had put together. I just love how well they integrate with other speakers I've used them with. They are a very musical Driver, I find myself enjoying music I seldom use to listen too.The RS315HF 12" Driver is AMAZING for its size. Make sure to buy two if you have a huge listening room. It just doubles your listening pleasure.
Date published: 2008-01-19
Rated 5 out of 5 by from ExcellentI replaced an NHT 12" sub with the RSS315HF and what a difference. These are the best value sub drivers on the market and the best looking. You simply can't go wrong with the Reference line.
Date published: 2007-12-28
Rated 5 out of 5 by from Awesome Sub.I installed this sub in a sealed 1.6 cubic ft. box with 300w of solid power crossed @ 80hz.It is very nice at low volume and just pounds like mad when you turn it up.
Date published: 2007-11-01
Rated 5 out of 5 by from Can't Be Beat for the PriceI put this sub together in a similar design as the RS1200 before RS1200 was available. After some EQing it has great low-end extension sealed, and with 500 watts it can put out more bass than I can handle in my 400sqft listening room. The woofer stays clean and crisp sounding even at high levels. For the price I don't think this woofer can be touched.
Date published: 2007-10-25
Rated 4 out of 5 by from A Real Audiophile DriverThis sub is well crafted and the performance in my home made sealed enclosure was beyond my expectations.
Date published: 2007-10-18
Rated 5 out of 5 by from This is a Best Buy Subwoofer/DriverVery musical...Can rock the house (and everything in it!)...Loud deep lows that can be scary! Recommended Best Buy @ $109.00!
Date published: 2007-10-17
Rated 5 out of 5 by from Great sub, well builtThis sub is built very good for the price, huge magnet, nice motor venting, integrated tinsel leads, all nice stuff. For my build I went with a 4.5 cuft. box with a slot port tuned to 19 Hz. I just finished a few hours ago but on my first movie experience it was actually moving the pictures on the walls, not a dinky picture either its a 24x30 with a metal frame, not light. I was extremly impressed with the ability of this sub, it played sounds my other subs have never even tried to before. Also, I used the Dayton 240 amp to power it

Rated 5 out of 5 by from Great performerIve been using this woofer everyday for 2 years.I use it un a large vented enclosure. It performs beautifully. Very low bass with no distorsion.
Date published: 2007-06-29
Rated 5 out of 5 by from High QualityI'm a speaker builder and have been using this sub in a custom built enclosure for over 2 months now. I am very impressed with the performace. It has musical qualities while still being able to fill a 3000cf room with bass quite nicely.

Rated 5 out of 5 by from BeautifulFrom overall appearance to build quality to sound quality, this driver just exudes beauty. I have yet to find a subwoofer that can deliver the same level of clean, musical output at such a low price. An excellent choice for someone wanting a musical sub that can also do a decent job with home theater duties.
Date published: 2007-05-29
Rated 5 out of 5 by from Haven't found a problem with it at allI've owned this sub for over a year and it's really a favorite of mine. I haven't experienced such clean and low bass perfomance like this outside of my IB sub installation. For the money I don't think there's anything better when it comes down to it. If there is another 12" sub out there that costs the same or less with the amount of performance the 12" HF possesses I would sure like to see and hear it. Still I don't think I will ever give up the RS. Plus it just looks great. Yep, it gets a five star rating in my book.

Dayton Audio RSS315HF-4 12" Reference HF Subwoofer 4 Ohm

what is the optimal enclosure size for ported sub?

i have this sub in a 5.1 cf box w/ 4 by 11 port. the combonation of the box & sub is too heavy. looking for something smaller like 3 cf or so. if you know the answer, can you give me the box size and port to use for optimal enclosure size
Asked by: KSHIZO
For this driver in a 3.0ft³ ported enclosure, your 4" port should be roughly doubled in length. Approximately 21-22" according to BassBox 6 Pro, referenced below for your convenience.

Whats the Big Difference?

Is there really a big difference between this and the Dayton Audio RSS315HO-4 12" Reference HO Subwoofer 4 Ohm?
Asked by: Tim 46528
The HF (high fidelity) subwoofers feature a two layer voice coil that has very low inductance and a lighter cone for music applications.The HO (high output) subwoofers feature a thicker cone and a four layer voice coil for high power home theater applications. They also work very well in small sealed enclosures.
