Dayton Audio RSS315HO-44 12" Reference HO DVC Subwoofer

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. The High Output (HO) drivers are optimized for automotive applications and equalized high-power home subwoofers.

Dayton Audio RSS315HO-44 12" Reference HO DVC Subwoofer is rated 4.3333 out of 5 by 12.
Rated 1 out of 5 by from Repeated failures, known problem with adhesiveThese drivers have a known problem that causes a part under the dust cap to separate and rattle. This was supposed to be fixed in 2014, yet it keeps happening.After three failures I have to advise not to get this particular driver. It's not worth the risk.

Rated 5 out of 5 by from Perfect small powerful subI bought this about 2 months ago for a subwoofer that I planned to take to college , I made a very heavily braced 1.5 cubic foot enclosure tuned to right around 25 for an estimated -3db point of 25 hertz, I have to say the results are amazing. Easily could be a subwoofer for a larger home theater system. Depending on room arrangement and sub placement I have gotten response down into 20 hz region. Easily compares with my 12inch dvc series dayton, but it is a third the volume. As other reviewers have said though, this sub requires a lot of power to actually produce the low bass. I am currently powering it with a Pyle pexa 8000. As you start to get into the higher drive levels you will notice that the cone will start to become warm because of how much power it is drawing. This isn't a problem honestly. As far as xmax goes, this sub seems to be able to go almost double its xmax before it will actually hit the back plate, as far as linearity is concerned, I have used it probably to 18mm and still had it linear. My port is a slot port that is 12x1 and 29 inches long curved into the box, it does make some amount of port noise when doing tone generation at low frequencies, but within any music or home theater content you would never hear it. As far as transient properties go for this sub it is incredibly clean and accurate, it does not sound sloppy. I was a little worried with such a high moving mass, but it sounds better than I could have hoped. From articulate jazz to the hardest hitting edm, this sub can do it all, and sound good doing it. I currently am using this in a tri-amped system taking 120 down, it could easily go up to 180 or 200, but I like the way my Kevlar mid sound in that range.

Rated 5 out of 5 by from Good SQ with correct power and box set-up.Purchased this and made a custom sealed 1.1 ft^3 box that fit under the rear seat in a Dodge Ram 1500 ex. cab. Powered with Alpine MRD-M605 rated at 606 w/rms verified on amp birth sheet. Works great, am thinking I may add 2" port at 7" long to bolster low end output. Have not had any problems to this point, purchased 11/15/13. Also thinking about purchasing another and running at 1 ohm on a Zapco ZX 2K amp. Making another 1.4 ft^3 box with 3" by 6.5" port. Will update with outcome.

Rated 5 out of 5 by from A very solid subwooferI purchased one of these to put into a 1.5 cu.ft. enclosure in the trunk of my car. I ran it sealed at first and it was very detailed and tight but dug down pretty low thanks to cabin gain. I later added two ports to the enclosure, tuning to approx 23 Hz. and with a subsonic filter with an 18Hz corner frequency to avoid unloading the cone below tuning. I have to say, the ported configuration wins hands down for listening to classic rock, country, or oldies. I am driving it with a 550W rms amp in 2 ohm configuration and it has more than enough output to rattle any loose trim in the car. If this unit has any drawback at all, it would be that it needs a lot of power to really get cooking, but i guess that's to be expected based on the voice coil length, cone mass, "small" Vas, and low resonance. Mechanically, this unit is built like a tank, I expect it will survive most any sane drive levels with ease. I find it is extremely accurate and detailed, which is exactly what I was seeking. The very reasonable price for a unit of this quality makes it a best buy in my book for automotive use.

Rated 3 out of 5 by from Great sound quality, not so great build qualityOk so let me start off with the good. This sub sounds excellent! Can't stress that enough. With a proper size enclosure, with a proper size port, this sub has an excellent range with a nice flat response. Perfect SQ sub that rivals much pricier options. Now the bad. The first one I received was basically DOA. Voice coil started burning up bad within 2 minutes of use, at low level and only 300w RMS feeding it (wasn't even a bass heavy track). Spent the $38 to ship it back, and P-E replaced it. The new sub worked great, sounds great, etc. Well it developed an issue after 2 weeks of normal use. I heard a loud 'clunk' and went to check it out- the dust cover blew off the sub, along with the hard plastic vent cover on the VC. Looks like it was poorly epoxied at the factory. I refuse to glue it back on myself, as I shouldn't have to. I refuse to send it back, since there is no way I'm spending another $38 to ship it. Very disappointed. I'll just use it as-is and hope nothing makes it way between the magnet and voice coil.

Rated 5 out of 5 by from Outstanding performance/excellent priceFirst of all, this sub was delivered when promised. It was well protected and professionally packaged. This subwoofer is sturdy and well constructed using first class materials. I dropped it into a MDF box with an internal volume of 1.5 cf with a 2" x 9.5" port. With room coupling the sub measured flat to 20 hz using pink noise and 1/3 octave real time analyzation.This sub sounds great without any EQ. It delivers fast articulate bass when reproducing music yet has the ability to deliver room shaking low frequency effects from movie soundtracks. When coupled with the Audyssey EQ provided with my AV/Pre Amp, the room effects were smoothed out and performance rose to an even higher level.I couldn't be more pleased.

I like the specifications on this sub and I'd be inclined to use it for home theater, but I'm wondering if you have any home theater subwoofer amps that are 2 Ohm stable. Is there an amp you would recommend for use with the coils in parallel?

Asked by: bbutterfield
Unfortunately we don't have any subwoofer amplifiers that are 2 ohm stable. You might consider the single 4 ohm coil RSS315HO-4 instead.

Can the two voice coils be put in series for eight ohms rather than parallel as it seems to be advertised?

Asked by: PoLoMoTo
Yes this woofer can be wired either way.

What's the deepest playing 12 for a .85 cu. F. Truck box? Boss amp 2 ohm mono, eq, is what I have. Real amp power is about 300 watts. I've tried a few old subs but that volume is too restrictive. Old alphasonik did well in 3 cu. F. But junk in.85.options

I noticed that the optimum Sealed Volume is 0.49 ft.³.  It is such a small cabinet.  Is this net or gross volume?  Any recommendations on pre-fab sealed enclosure for this sub?  What is the volume of the sub itself?

Asked by: bpwells
This volume is net. The woofer displaces 0.135 cubic feet.

Is it ok to bottom mount this sub?

I'm looking to run a single 12" for an SQ set up for car audio. My question is how does the HO Ported compare to the UM Sealed? What is the best size box for the HO ported after sub and port displacement and correct port length? UM needs 3cf sealed?

Asked by: Jcarp
In order to get a relatively flat response the HO will need about 2.5 cubic feet total tuned to 29 Hz and heavy fill. This will be louder when compared to the Ultimax and have a stronger bottom end, but will roll off sooner and not play as low below about 25 Hz. The Ultimax will work in smaller enclosures with good results in a car application, 2 cubic feet will work well.
