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 4.7143 out of 5 by 49.
Rated 5 out of 5 by from Only one night in, but certainly shakes the house!I recently installed this into an empty AV123 MFW-15 Moho cabinet I bought at the AV123 auction when they were going out of business. Since I've been satisfied with the bass output of my AV123 LS-6's, the cabinet sat in my garage for the last 5+ years waiting for a "turbo upgrade" I could never afford. After reading a review on a another forum where someone installed this woofer with success in a MFW cabinet, I decided to give it a try and couple it with a Bash 300 plate amp for about a third of the turbo upgrade price. I am barely into break in at this point, but after a few hours of listening to Dolby Atmos demo's and a couple movies segments, I can easily say that I made the right choice to buy this. The LS's have plenty of musical bass output and I'm really only craving the seat/window/house shaking experience that I was lacking and this certainly does the trick!! I will play with some more settings tonight, and test some music on it as well, but needless to say it was money well spent and If I should need a car subwoofer in the future, this will be it as well. Great product at a great price!!!

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.

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

Would the 2.88cuft sealed box be ideal for music with the SA1000 amp?  Will there be a risk of oil canning?  What would be the optimal box size with this configuration for music only?

Asked by: sanddam45

what is the max spl of this subwoofer

Asked by: donglebass

How well will this do with the Dayton 250 watt SPA250 plate amp in a vented box? Will I be lacking a substantial amount of output by only having 250 watts?

Asked by: john503
That will certainly be able to drive this sub. Doubling power will really only get 3 more db so it is not a huge difference in output. The main advantage you wall have with additional power is more headroom for large peaks.

Looking at your subwoofer kit that uses your SPA1000 amp and two RSS315HFA-8 12" speakers.  Was wondering if I replaced 12" speakers with 15" say RSS390HF-4 15" if they might mate up?  Matching my Kiplish RSW15 dual subwoofer

Asked by: Home theater
you would not be able to use a 15 in the same box as they have very different airspace requirements.

I understand that this is the recomended speaker for BFM Home theater horn loaded sub. My question is would it also be suitable for Dj use in that configuration.

Asked by: Dj ZONE
The THT was designed for *HOME* *THEATER* use (hence the name). The driver is not a pro level driver, and the volume of the enclosure is appropriate for home use, not for nightclub / bar use. If you want to play gigs, build a pro sub, like T24, T30, T45, T60. BFM had many designs, each well suited to their own realms.

I have a pair of these (RSS390HF-4) that i am putting in a 4.75ft3 sealed boxes. I'm looking to power them with either a QSC GX5 or maybe go a little cheaper with a Behringer EPX2800. Any thoughts on which 1 or should I go with something else entirely?

Asked by: BalooTheBear
Either of those will work in terms of power output. You might also consider something like the NU3000DSP which will help you dial the room response into something much smoother sounding.
