Product Details

Dayton Audio RSS315HFA-8 12" Reference HF Subwoofer 8 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 the RSS315HFA-8 12" driver is ultra-low-distortion. Second, third, and intermodulation distortion are kept extremely low by utilizing three magnetic 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 this High Fidelity (HF) version for home speaker systems when your priority is clean, low bass and you are not restricted by cabinet size.

Dayton Audio RSS315HFA-8 12" Reference HF Subwoofer 8 Ohm
Dayton Audio RSS315HFA-8 12" Reference HF Subwoofer 8 Ohm is rated 5.0 out of 5 by 4.
Rated 5 out of 5 by from bad a** and wow!I used it in my surefire/bob carver box and it sounds awesome! the stuff rattles off my walls. It may be better than the original.

Rated 5 out of 5 by from Great SoundI matched this driver to the Dayton 2cu ft cabinet, and what a great combination. I am using only one channel (125W rms) of a backup amp while my dedicated sub-amp is being rebuilt, but wow even with only 125w pushing it the bass is nice and low and even (not thuddy) at medium volume levels.I am choosing not to port the cabinet for now since the bass is so tight and smooth. There is some drop off at very low freq but I was expecting that with this setup and no port.Music sounds rich and full and this is what I bought this unit for (paired with Mordaunt-Short satellites). Movies also sound great although I can't get the really intense bass yet as 125W is not enough to shake the house.Overall excellent bass driver.

Rated 5 out of 5 by from excellent sub for 8 ohm applicationsI am using two of these in seperate cabinets due to the odd shape of the room I am using them in. I am using these with a SA1000 Dayton outboard amp. These units perform very well together. The manual for the amp states not to go below 4 ohms so i chose these drivers. I originally used them in a 3 cubic foot sealed enclosure. I have since ported the cabinets (first one and then the other). They seemed to work well in both applications. I use them for movies, but mostly for music. I am very pleased with the overall performance. As you can imagine, I do not lack any bass response.

Rated 5 out of 5 by from great soundi matched this speaker with the dayton 240w b amp and it sounds really great...at first i was thinking i should have went with a more powerful amp but i tried the 2 together in a 2.5 ft sealed mdf box and the bass is punchy and low even at low volume, i am very pleased on the sound quality and the wall shaking capabilities of it all...i gave the value a good just because i'd wished i could of got it on sale, still a great sub speaker...

would this be a good upgrade for a klipsch synergy sub 12?

Asked by: tdog979
The best woofer for that enclosure would actually be the Dayton Classic 12" subwoofer below.http://www.parts-express.com/dayton-audio-dcs305-4-12-classic-subwoofer-4-ohm--295-204If you wanted to use a Reference series sub, the RSS315HO-4 would be the best option.http://www.parts-express.com/dayton-audio-rss315ho-4-12-reference-ho-subwoofer-4-ohm--295-466

This says optimized for large enclosures, I have a large ~10.5 cu.ft. 2x12 ported box which I am looking to upgrade. This sims well, but the HO-44 (295-467) goes a little flatter/lower (f3~15Hz). Am I missing something, or suggestions for my box?

Asked by: JoeKewl
The best option for that volume is the RSS315HFA-8. The HO-44 will lack output and sensitivity in such a large enclosure while the HFA-8 will handle full power and have 3 dB more output per watt overall.

Is this considered a long throw?

Asked by: mikeado
The term "long throw" simply means high excursion and this would be classified as a high excursion driver.

Clarifying the formula for downward firing subwoofers.

The formula for the calculations is: Percentage of Sag = 24,849 / ( Xmax * Fs²). However, according to the explanation of sag, two variables (Vas and Sd) are missing from the formula. It says: "You will need the Fs, Vas, Sd (surface area of the cone), and the Xmax to determine the relative long term usefulness of up or down-firing any woofer." If Vas and Sd are needed to determine sag, why aren't they included in the formula?
Asked by: trackfan
To find sag you will need to find your Cms then Mms and then Sag.Cms = Vas / (1180 * c^2 * (Sd/10000)^2)Where:c = speed of sound (m/s). Generally 343m/sSd = effective surface arean in square cm (cm^2)Cms (m/N)Mms = 1 / ((2*pi*Fs)^2 * Cms)Where:pi = 3.14159Fs = resonant frequency (Hz)Mms (kg)Sag = Cms * Mms * gWhere:g = accerlation of gravity 9.81m/s^2You sag should not be more than 5% of your XmaxPercent of Sag = (Sag/Xmax) * 100I believe Vas, Sd, and Xmax where all used. However if you look at the spec sheet Cms and Mms are already given (0.21 mm/N and 195.2 g respectively).So Sag = 0.00021*0.1952*9.81 = 0.000402 meters (0.402mm)%Sag = (0.402/14.3)*100 = 2.81% = GTG [Good To Go]!Best of luck and I hope this helps.
