Dayton Audio RSS390HO-4 15" 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 intemodulation 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 subwoofer speaker systems.

Dayton Audio RSS390HO-4 15" Reference HO Subwoofer 4 Ohm
Dayton Audio RSS390HO-4 15" Reference HO Subwoofer 4 Ohm is rated 4.8788 out of 5 by 33.
Rated 5 out of 5 by from Absolutely AWESOME driver.Wow, this thing is really amazing, more so than I even imagined. I have it in an old Elemental Designs a5-350 as a replacement driver, the stock driver stopped working. I also have two mfw-15 subs with TC Sounds 15" TC2000 drivers. As awesome as the TC Sounds driver are, I will say, the Dayton quite easily keeps pace with them. I was very surprised by this, considering the TC Sounds drivers have a larger motor, more xmax, and weigh a good 10lbs more. I was shocked at how powerful this driver is!! The build quality is simply TOP NOTCH. Very very nice looking in my a5-350. The stated xmax MUST be in error or is understated. This thing gets way more than 12mm of xmax, no doubt about it. Dayton is just being humble. :D Seriously, don't hesitate, this driver will rock your world!! :D

Rated 5 out of 5 by from Works great in my MicrocubeI used this subwoofer as it is what is suggested for a popular subwoofer plan I was following. The plan is for a 3.75 cubic foot ported enclosure tuned to 23hz however I decided to increase the volume to somewhere around 4.5 and tuned it to 22 hz. The subwoofer is of really high quality. It's my first build but I am incredibly satisfied with it.I'm powering it through a Inuke 3000dsp bridged with a HPF of 22hz. I almost want to try going a little lower as it seems as though the subwoofer would be able to handle it.Anyways, this is pretty much the obvious choice for this size and price point. Unless you want to go for a 18" in which case a whole new world of subwoofers is awaiting you.

Rated 5 out of 5 by from wonderful subwooferI bought this a week ago.. It's in a vented downfiring configuration, 4 cubes with a 4 inch port 16 inches long tuned to 22hz and it sounds soo smooth paired with tritrix speaker towers!!

Rated 1 out of 5 by from JunkSo I thought I had just a defective subwoofer because after only having the first one installed for a week it came apart, it had always made a random weird metal clanking sound since day one until it came apart, we'll I just received my replacement today and it makes the same sound, so I'm guessing it's not gonna last very long either. I will say it does sound very good until it starts to make the random clanking sound, but that's just not what you wanna hear coming from your sub.

Rated 5 out of 5 by from Simply Outstanding!I’ve owned two of the Dayton RSS315HF-4 12-inch subwoofers for 5 years and found myself increasingly dissatisfied with them. Not that there is anything wrong with them per se, but I wanted something that would reach deeper and with more authority. Let’s face it, generally speaking a 12-inch driver simply does not reproduce the lows with the authority of a 15-inch, even though it may “model” well in software.So my goal was to find a 15-inch driver that would be good for porting but not require an enclosure the size of a refrigerator. Using WinISD, I modeled every 15-inch subwoofer Parts Express carries. Lo and behold the RSS390HO-4 came out on top by a long shot. In the same size enclosure I was using for the 12-inch RSS315HF’s I could put a 15-inch RSS390HO-4 and experience much more volume and depth.I built a well braced enclosure using stain-grade laminated pine and 5-minute epoxy – my material and method of choice for a few years now. It makes for a quick build and much lighter enclosure compared to MDF. I used 1.5 x 1.5 x .75 inch solid oak blocks that are epoxied to the back of the baffle for the 1.5 inches wood screws to sink into to mount the subwoofer.The enclosure has a net volume of 3.25 cu. ft. and is 24” high x 16.5” wide x 20.75” deep. I used a 4-inch Precision Port cut to 16.125 total inches in length, and 2-inch fiberglass insulation for cabinet dampening. The result is a frequency response that is flat to 25hz and rolls off to 20Hz.A side note: The subwoofer itself weights 23.5 pounds. The weight they list in the description includes packaging material.I am currently powering it with the Dayton Audio SPA500 500W Subwoofer Plate Amplifier which does a great job. I have it in my audio rack that sits right next to my listening chair (La-Z-Boy recliner). When I am in the mood for extended low end I use the EQ with “Freq” set to 18hz, “Bandwidth” set to 1, and “Level" set to +6dB.The copious amount of bass that comes out of such a relatively small cabinet is simply amazing. I am VERY satisfied with my purchase and HIGHLY recommend this subwoofer!

Rated 5 out of 5 by from Best 15 I could ever wish for!I was looking for a subwoofer for my home theater/music room and I could not find one with the low end extension I wanted #my polk psw 10 couldn't go below 40 hz#... I was on a budget so I was looking at brands like kicker, Rockford, Cerwin Vega etc.. until I crossed paths with this magnificent subwoofer. it was out of my price range but I saved up and eventually bought it with the BASH 300 watt plate amp that was on sale for $110. I was going to get the knock down cabinet but modifying it to be ported seemed like more work than just building my own. building mine was easy as pie, went to lowe's, had them cut me pieces of 3/4" MDF so i can build a 20" cube and then I assembled it. glue, silicone, screws, and poly fill which definitely made it go deeper. when the box was done I used bondo on the edges and painted it glossy black which was a big mistake. it came out like COMPLETE garbage so im saving up for some vinyl laminate so i can fix it, but for now it functions like it should. long story, not so short, I built the box to 3.4 cubic ft. after sub+port displacement and used two 3" aero ports to tune it to 26 hz. and it sounded amazing! it goes as low as 16 hz, and at the same time it can be punchy and hits higher frequencies with ease! im comparing this to my kicker L7 in my car and I just want to ditch the kicker after hearing this subwoofer! my kicker pumps mud, cant go higher than 70 hz, and wont go lower than 24 #w/ the box built to kicker specs and tuned to 32 hz#. for the price of one L7 i could have gotten 2 of these daytons! this is a great subwoofer, high quality and can get loud and low when you want it too. for my first DIY subwoofer at the age of 18 i am very pleased with the outcome and im NEVER buying name brand subs again. $400 and a day or two will get you a sub on par with the big boy subwoofers that cost upwards of +$1,000. trust me, get this and build your own powered sub, you'll never go back to buying Chinese made HT subs again!

I HAVE  ONLY 2.1 FT3  NET INTERNAL VOLUME. I WANT TO GO SEALED FOR HOME THEATER AND MUSIC. HOW LOW CAN I REACH WITH AN ENCLOSURE OF 2.1 ft3? THANKS.

Asked by: Gioxtream
In that volume sealed you will have an F3 of about 50 Hz and in room response into the mid 20's. This should work well for music and home theater.

If I want to port externally, out the back, with one or two ports that are rectangular, made of wood, like 2" or 3" by some large width, what size would work? I could route the wood thickness for a 0.75" radiused flare in and out.

Please recommend one or two grill part numbers to protect this RSS390HO-4.

Asked by: blakely
The only grills we have that will fit these woofers are our bar style grills which you can see below.http://www.parts-express.com/15-bar-grill-chrome--260-444http://www.parts-express.com/15-bar-grill-black--260-445

This driver should be excellent in a 3 CF box vented for 28 Hz. Any drawings, parts list, or kit available how to do this with your standard 3CF box? If no kit yet, it seems it would be one of your best offerings if you did.

Asked by: Blakely
Porting this kit would be possible but the ports would require elbows. I would recommend two 4" dual flared ports that are 27" long for a tuning frequency of 28 Hz.

Would a 5.3 cubic foot box with dual 4 inch 15 inch long ports work? Or would it be worth my while to try to extend the ports to 20 inches each. 

Asked by: Mosbro18
Dual 15" long ports will work fine and tune the box to 24 Hz.
