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 is rated 4.7083 out of 5 by 48.
Rated 1 out of 5 by from Voice coil came apart 300w Dayton denies warranty.Has this sub the 5.3ft enclosure recommended by Matt P on here 15 min into our Christmas party it starts making scratching noise. They said the voice coil former was bottomed and broke off, or as I suspect, the voice cool split and bottomed before I could get over to shut it off. Anyways, I replaced it with a Stereo Integrity HT18 rated at a lower rms@ 600 but it sounds better, it's louder and will definitely handle more power. I own 9 other Dayton audio products but after their handling of this I won't buy again.

Rated 5 out of 5 by from Amazing sound quality and depthI went from a 12" RE Audio sub at half the price to this sub and could instantly hear and feel the difference. It looks great in my Dayton Audio 2 cu. ft. Cherry Cabinet although the grill doesn't fit right because of the width of the frame. I'll try extending the grill with some round disc magnets.

Rated 5 out of 5 by from Great value, excellent product, fast safe shippingGreat value and very fast and safe shipping. I bought the sub to replace a torn cone subwoofer in an older Definitive 1500 Powerfield sub that was otherwise in good condition. This company was recommended by a Definitive tech because they didn't make a direct replacement anymore. The told me what to look for and I found and installed this sub myself. The bass is fantastic and nice and tight. I couldn't be happier with the purchase.

Rated 5 out of 5 by from Made an Audiophile subwooferI wanted a music sub woofer, not a boombox, to compliment my Klipsch LaScala speakers. I installed this Speaker in a sealed 5.5 cu ft well braced box made from birch plywood lined with fiberglass with wood screws 3 inches apart. I made a separate box for the Bash 500 plate amplifier to keep the box good and tight. I wanted good low tight defined bass to blend with the horn loaded bass from the Lascala's. The sound is superb and exceeded my expectations. I hear now what I have been missing all these years. Bass like this was unattainable when I first started buying equipment but with 500 watt amplifiers and 15" speakers that can take the power it is now possible at a reasonable cost. Be forewarned that this is a large box and the speaker would most likely sound as good in a smaller box but size is not a problem with me. Parts Express service was superb. For some reason there was not a power cord with the Bash and after calling them one was sent that day and I received it 2 days later.

Rated 5 out of 5 by from Very Good SubsBrilliant speakers, use two of these to play Dub Reggea, very nice clean & Deep Bass at low volumes.Delivery was quiet quick with no problems.I have already recommended to friends.

Rated 5 out of 5 by from Brilliant Sub Woofer!Brought this online as a third attempt meaning this was the third company I tried to purchase from, success I have purchased & happy with a first class service.Even though others said they had issues the service I had was very good, the package arrived a day earlier than estimated.The main thing is the trust as my two previous orders one through eBay the other a company I assume well known Europ-Aud..... took my payment guickly with no reply corespondents communication or item THEIFS, so please read reveiws when ever you purchase onlineI am one of the old school Bass Heads & love my Bass, had an old Celestion Bass Speaker in a sealed enclosure vow that sounded great perfect (no model or spec details) even though it was a 15" maked up as 50Ws 55c/s Hz & 4ohms, I later learned the basket itself had lot of different coils dependent on company's specifications.The box it came in was about 3-1/2 feet high by1-1/4 wide less than a foot deep, but sounded very very deep due to the speaker.This was over 25 years ago & I've searching for years after I gave up looking for the exact speaker for a modern equivalent, but I did know this speaker had a Low Ro as everything played through it sounded deep.To end a very long story & trying out numerous speaker even Cerwin vega with there rep (still not deep enough) I read on line about the Dayton Audio RSS390HF-4 15" Reference HF Subwoofer 4 Ohm, the spec sounded good also the reveiws.Now I listen to Dub Reggea & old Reggea as well as soul music House Garage Deep House the usual stuff, I'm only using one of these driver so far & am very please with thus so far.These drivers brings the music alive a full circle they are great very deep with a EQ & Bass processor (not everyone likes them) but I am quiet satisfied can't wait to connect up the other speaker.I am also looking at the Dayton Audio TS400D-4 15" Titanic Mk 4 Subwoofer 4 Ohm, check out the spec goes down to 17.1 Hz Ro.I love Sub Base!

Is the cone attached in a way that allows it to act as a heat sink for the voice coil? Aluminum cone speakers I had in the past used an all metal connection instead of just glue to help cool the voice coils. 

Asked by: mende21

I will be using a external amp rated at 200 watts per channel @ 4 Ohms. Will that be enough power to run this Sub?

I have a 13cu ft box that is built into a room (1.5in thick on all sides). I think 2 of these would be good (sealed) for Q=0.66 and f3=42Hz. What other drivers would you recommend I look at for a 13cu ft sealed box? I like Q from 0.5 to 0.7

Optimal sealed size for rss390hf of 2.88 ft3 does not match my own calculations. How well stuffed should it be on that volume? Based on your calculations what is the Q? Plan on running two 390hf's on the SA1000 Amp. Risk of oil-canning?

Asked by: henrik1
That volume takes into consideration the driver displacement and is calculated with average stuffing, which is about 1/2 pound per cubic foot of airspace. The Qtc of this alignment is 0.707. If you are going to run two of these on one SA1000 they will have to be wired in series for an 8 ohm load. I would not worry about oil canning in this configuration.

I understand that its not optimal to put this in smaller sealed enclosures. I'm not sure if this is due to suboptimal Q or due to cone excursion on higher watt amp? Winisd shows around 120l net (unstuffed) as optimal. 100L net stuffed should give good Q?

Asked by: henrik1
A slightly smaller enclosure will raise total Q which helps keep excursion under control in a sealed box. the difference between 120 and 100 L will be negligible, and lightly stuffing the enclosure will help make up for this.

I have an old Velodyne F-1500 enclosure with a bad driver. Exploded the VC, no simple trick I suspect. If this a good match for that cabinet IF I also change out the amp? And.. what amp would be good?
