Product Details

Dayton Audio RSS390HF-4 15" Reference HF Subwoofer 4 Ohm

The Dayton Audio Reference Series RSS390HF-4 15" speakers 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 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 the high fidelity version for home systems when you are looking for clean, low bass and are not restricted by cabinet size.

Dayton Audio RSS390HF-4 15" Reference HF Subwoofer 4 Ohm
Dayton Audio RSS390HF-4 15" Reference HF Subwoofer 4 Ohm is rated 4.7619 out of 5 by 42.
Rated 5 out of 5 by from Very Happy! Low, clean, and excellent transientsA little back story: Had a wonderful Velodyne ULD-15” Series II subwoofer system. The system has a separate 400W amp and sub enclosure. Loved that Velodyne. However, something in the accelerometer feedback loop went bad, which made the amp useless. Couldn’t be repaired.Decided to purchase a HPSA500 500W Amp (part# 300-806) a while back to drive the subwoofer instead, without the feedback loop. Worked o.k., but had problems with lower bass extension and I couldn’t drive it very well at low frequencies (<35Hz) without getting soft popping and ugly noises.Decided to purchase this RSS390HF-4 subwoofer for the following reasons. I wanted a sub with excellent transient response. -Check. The low Le on this model is perfect for that. I wanted a sub that is good for a sealed enclosure, with good X-max, and a low fs. -Check, -Check, and -Check. I placed this sub into the sealed ULD15 enclosure, which is roughly 2.9 cu ft internal after the sub and bracing (which I added) is accounted for. This is on the small side for this sub, but I had the enclosure handy and I had the ability boost low frequencies with the parametric EQ on the HPSA500. With 2 lbs of fill, and the eq on the amp, I’m currently getting a -3dB of about 23 hz! The sub is amazingly transient, and the motor is silent. It goes low, and it does it cleanly and with excellent transient response. I AM THRILLED WITH THIS SUB. It matches extremely well with my B&W CDM fronts and centers for both music and film.

Rated 5 out of 5 by from Great Sub & it can go LOWWWW!!!I have a Brian Cheney Limited Edition VSS Sub from VMPS The old wooferdeveloped a rattle. I replaced that driver with the rss390-hf and I could not be happier! I Also replaced the Big Bump Passive Radiator at the same time with a TC Sounds PR. Great combination!

Rated 5 out of 5 by from Another 5-Star ReviewI have a pair of these in 3.7 cu ft unported cabinets as recommended by PE tech support. I could not be happier with the sound. Smooth yet tight and as powerful as you need them to be. I have them crossed over at 125hz via Crown XLS amps which transitions seamlessly to my Beyma 15" Coaxials. Would absolutely not hesitate to buy again.

Rated 5 out of 5 by from Best subwoofer for the moneyWith this sub you can obtain an extremely pleasent bass extention. It has a really soldi construction and has features that only drivers costing double as much have. I've built a 135Lt closet enclosure around it, Absolutely reccomended.

What would be a good amp match for this sub?

Just wondering what amp is recommended with this sub.
Asked by: iGuitar93
The Dayton or Bash 500 watt plate amps would both be a good match for this sub.You usually want to keep the power rating of the amp close to the power rating of the driver.

What is the optimal ported tuning for a box around 5 to 6 cubic feet w/300 to 350 watts?

I've played around with winsid and have a 5ft cube w/2 4" 38" ports.
Asked by: JVoodoo
Have you taken into consideration the room dimensions it will be playing in and the location of the listening position relative to where the subwoofer enclosure is placed? These will all affect the bandwidth you are aiming for, but 1w/1m numbers will not reflect any of these response-changing variables. Even the direction you face the subwoofer will make a world of difference. It could be a tapered transmission line or a front loading horn that's required to yield your desired results. It is possible that no bass-reflex alignment could present the required bandwidth.

What is the ideal sealed enclosure size for this driver with sound quality in mind?Further, what would be an acceptable compromise with how much fill?

Asked by: JDomer
Hi J168 Liters will be the minimun to get the best performance.The knee -3db will be arround 28 Hz and the spl will be arrond 114 dB.Make it well braced and sturdy. 1st quality Baltic Birch is my recomendation. Dont use MDF. Will come apart under his own vibration.will shake a lot.BestDavid

I wanted to get 2 of these and put them in a sealed enclosure for my car. I'm trying to have a smallish size box. What size box would you recommend?

Going to be running both with a Jl 1000 1
Asked by: Landon
I wouldn't go any smaller than 5 cu ft for two of these. The 3db down point is roughly 30hz this way so it should still sound pretty good.If you have more room you can definitely use it, but any smaller and the response starts getting ragged and sloped below about 50hz so you would lose a lot of what most people want in car audio sound.

Will this enclosure work?

Would a pair of these work well in a setup like this? Each sub would be in it's own enclosure with 5.3ft^3, 4"x15" 55" port. They would be powered by a QSC RMX-850. This will mostly be for HT, with some music mixed in.
Asked by: Big D
If you search for the WOOFER SELECTION GUIDE and find this driver - it will give you good starting points for sealed and ported versions of this driver. Porting extends bass much lower with the T/S specs of this driver - but for a port tuning of 21hz, you need a 9 cubic foot cabinet. When building a cabinet with a large port - split the port area into multiple tubes. JBL has done this over the years using 2 or 3 smaller tubes rather than one very large one. As for the QSC amp - the one you are choosing is under-powered. Options would be two of them in mono (ideal) or an RMX 2450.
