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.

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 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!

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.

Can this subwoofer be used in an Infinite Baffle situation?

Asked by: Shepherdman

How would this work in a 4th order bandpass with a 2:1 ratio with 4 cubic feet ported and 2 cubic feet sealed with the ported section tuned to about 42hz and about 60 sq. inches of port area?

Asked by: Tyler99
There are quite a few problems with this. The driver will work fine in a fourth order bandpass, but the volumes are different, that port area is far too large and the port length required for that type of tuning frequency is over 6 feet. The volumes recommended for this woofer are 3.6 sealed and 2.8 vented, with a 2" x 16" port that is 23" long. This will provide a tuning frequency of 34 and passband of 20-60 Hz.

Which one of your subwoofer speaker cabinets would you recommend? I'm looking to build a sealed up with either the dayton 250w or 500w amp. Would the Dayton Audio SWC3-VI work well?

Asked by: CheesyHotDogPuff
Yes that would work well with this woofer, as well as any other 3.0 cubic foot enclosures we offer.

Date published: 2015-02-23

I have 2 Paradigm Servo 15 v1 enclosures with blown subs/amps. I am looking for a pair of replacement subs to put in these roughly 3.0 cubic foot boxes and run off an older Precedent 900a (590wpc @ 4 ohms; 775wpc @ 2 ohm). Would these be a good option?

Asked by: egilber1
We do not have a cross reference available for this type of thing. Please contact our tech support for more help with this question, tech@parts-express.com or 800-338-0531 x1.

Wanting to build 5 cu ft downfire sealed would this work and what would you recommend for spacing from the floor

Asked by: Swede1
Yes this will work fine for that application. I would recommend 4-5" of spacing from the floor.

Hi, My youth group has two Mackie SRS1500 subwoofers with ~3 cu. ft. internal volume. Would these offer an improvement if I sealed the cabinet?

Asked by: ivandezande
The Mackie subwoofer is a bandpass type design so sealing it up will result in virtually no output. The woofer that is in the enclosure will be the best option.
