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 4.6 out of 5 by 10.
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.

Rated 4 out of 5 by from Great SubsHad a custom box built for two of them that would fit between the wall and the couch. Powering them both with the Dayton 1000 watt HPSA1000-R.

Rated 5 out of 5 by from Dayton Does It Again!!I am currently running 2 of these each in it's own 1 cu.ft. sealed box and I am very happy with their performance. I bought a pair of Mag 1.7's and I have read that it is hard to blend them seamlessly with a sub to acheive the lowest octave of bass. Fortunately with the Daytons, that has not been an issue at all! I have them crossed over pretty low at about 50 hz and they do the job wonderfully. I am runnig them off of the Dayton HPSA 1000 rack amp, another flawless performer. Also, the dual 4 ohm voice coils make for more wiring options. I have used them in my home theater setup too and the low bass output is AMAZING!! Highly recommended.

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.

I installed this speaker in a 2.4 ft^3 net volume cabinet with a 3"x15.5" vent tuned to 21hz. I modeled the speaker with WinISD software for a nearly flat response from 25 to 100hz. Would the 1.3 ft^3 produce a more extended lower end in the real world?

Asked by: cuinches
A smaller volume will produce more output above the tuning frequency. The larger cabinet will have a more extended low end in the real world, depending on application of course.

2.5 cf box w/ 2 4"x10" ports ok or would the rss315hfa-8 be a better choice

Asked by: tmh57
That volume and port size will tune the box to about 43 Hz which is pretty high, and will cause a peak in the response. A single 4" port will drop the tuning to 31 Hz but will still have a bit of a peak. The HO model will be better suited for a vented box but knowing where you would like it tuned will help with modeling.

if i put the Sub in a sealed box of 19 liters, What is the minimum power required by the amplifier? is 200W is enough for Average Apartment?

Asked by: asher
There is no such thing as minimum power without knowing the output levels you are trying to achieve with a given driver. 200 watts will work for low to moderate levels but headroom is always recommended with subwoofers, even if they aren't turned up very often.

In the description it said Bassbox pro suggest sealed .49 cu ft for this sub.  Is this right?  It seems a little small to me. What is the proper sealed enclosure for this sub? Thanks

Asked by: JoeDD
That volume is accurate for this woofer.
