Dayton Audio RSS210HF-4 8" Reference HF 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 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 Great Replacement SubI bought this sub to replace a blown paradigm HT sub. It sounds better than the original equipped sub using the paradigm enclosure.

Rated 4 out of 5 by from Doesn't like to be portedI chose this driver for my first ever subwoofer build based on it's excellent reviews and price point, but i found designing for it to be a bit difficult.I knew from the gate i was going to build a sealed sub, but for fun i decided to model both ported and sealed. According to WinISD this thing does not like to be ported what-so-ever. No matter what combination of box size/port/power i chose (unless the power input was like, lower than 25W), the xmax was far exceeded down around mid 20's or so. So obviously i ditched ported all together and went with a sealed box ~.8 cu ft. and matched it with a 100W plate amp from another website. I found this combination to be excellent for this driver, however the power is still a bit more than this thing wants. I had to calibrate it a few Db lower than my other speakers in order to keep the excursion in check during the intense movie scenes (specifically Iron Man 2 and the Skidoosh scene of Kung Fu Panda). If i kept it calibrated at the same level during those scenes the woofer looked as though it was going to jump right out of the box and distortion became extremely audible even 4-5 ft. away. If i had to do it over i would put it in the same sized box with a 75W amp so i could avoid the excursion issues.Even with these difficulties though i am pretty pleased with this build. Music has come alive as bass notes i never knew were there jump out at me and movies now have that impact i was looking for. I must point out though that this sub alone would not cut it, even in my very small room. I have it paired with another sealed 300W sub and these babies play very nicely together. Response in my room has become relatively flat (compared to what it used to be with the single sub i had before) down to around the mid 20's and has usable output down to about 20hz. I used to not even get a register on my SPL meter until about 30+ hz.All said and done i am very pleased with this sub. The build quality is excellent and it can give decent response down low. Even though i am an extreme amateur, i advise against porting this thing unless you know exactly what you're doing. One slip and a sneaky 18Hz tone finding it's way through and you may be in a world of trouble. That's my 2 cents anyways, cheers~

Rated 5 out of 5 by from Follows the rest of the RS lineThis is truly an incredible 8" driver. Off of the top of my head, I believe that I own 6 of the RS subwoofers: 2 12", 3 10" and this 8". Although I focus on home audio applications, I do enjoy mobile sound. I was using the 10" RS subwoofer in my car with the front stage being RS 7" midwoofers in a 2.5-way with CDT tweeters. The 10" simply had too much output for the modest 300W I was giving it ported, so I decided to go even further down the SQ path and chose this driver and sealed it up. Put in a few different internal damping materials, but eventually settled on fiberglass lined walls with loose polyfill throughout. While it does not have the low-end extension of the 10" (obviously to be expected), it is more musical. Works excellently for everything from Diana Krall to DJ Tiesto to Maroon 5 and Tech N9ne. If you don't know who all of those are, just know that this speaker is all things to all genres!

Rated 5 out of 5 by from Nice MatchI used these to replace the woofers in my Polk RT2000p sub module and they fit the bill perfectly. I had read on several sites that these were the closest woofers to what I had so after several recommendations I went with them and was WELL pleased. They are a little boomier than the Polk's but that's because of a sight difference in build and necessary box size (and the Polk's were sound perfection in my opinion). I simply keep them a bit lower than the other side and they sound fine. A great woofer for the money

Rated 5 out of 5 by from Almost ScanSpeak quality, but less output...In a 1ft^3 box, with a 2.5"D x 10.5" long vent, you get an FB/3/10 of 30/26/19Hz. They can play cleanly up to 800 Hz to meet a dome mid if preferred, are clean to the T, and give deep bass in a very small box. The only lacking quality is sensitivity compared to the Scan Speak 22W/8857T. I would trade a bit of box size for a little more output potential, so I would recommend at least 200-300W/ch amp if using these in a stereo pair as I did.

Rated 5 out of 5 by from A Legitimate 8" SubwooferI have one of these installed in about ~.4 cu.ft. (moderately stuffed) in the cab of my truck on 150 watts. There is no doubt that this is a true subwoofer, comparable to some of the most well respected models in the car audio arena.The RS 8" is capable of delivering solid performance below 60hz with good output and low distortion. Some eq is necessary to compensate for the relatively high roll-off, but that's to be expected. If you are limited on space for a real subwoofer, look no further than this.

Dayton Audio RSS210HF-4 8" Reference HF Subwoofer 4 Ohm

Hi there I want to build full range 3-ways using this woofer, the RS 180-8 as a midrange and the PT2C-8 tweeter with the XO3W-375/3K crossover. I would like a lower in-room frequency response of 25 hz. Is this viable and will the impedance be? Thanks.

Would this be a good replacement for a Sunfire Super Junior sub? The original surrounds on both the woofer and passive are shot and nobody seems to make replacements. Would it work well with the SD215-PR passive radiator? The box only measures .3 cu ft

Asked by: Trevor Phillips
The best woofer for this application would be either the Dayton RSS210HO-4 or the TC Sounds Epic 8". Unfortunately we do not have a suitable passive radiator for either of these options.

I would like to put 2 of these in a sealed enclosure. I have figured around 2 cf with the 240w P.E. amp. Does anyone see any issues with this? Approximately what would my bottom extension with this set-up be? Thank you.

Asked by: mace
I would recommend two of the RSS210HO-8 woofers instead. This will yield a 4 ohm load for the amplifier which will provide the full 240 watts. A pair of these will work well in about 0.9 cubic feet sealed and provide in room response into the upper 20's.

Need 2 subs for 7.2 set up - I would like to use sealed boxes for music acuracy and some kind of "low freq bass eq" to get lows for HT use? Space is limited Im in a townhome, need smallest box possible w/eq to get best of both worlds. HELP! 

Asked by: NCaudio2
I would recommend the HO version of this woofer in about 0.5 cubic feet per woofer. This will handle more power, more excursion and basically more EQ than the HF. This will be able to get into the mid-20's at medium volume levels.

I would like to know if these can be used in a vertical orientation. That is, with the cone facing up or down.

Asked by: RSSwoofer
Yes it can. The only concern is when facing down, be sure there is enough air space below it. As an example, if the Bass box is 12" X 12" X 12"--you should allow 2-5" of space to allow the large low frequencies to "breath". An even better approach is to raise just the front about 5". This gives the woofer a boundary. Kind of like a half horn load. I did this on a large format system to create an earthquake effect. I only had to use 1/2 of the speakers for the same volume level I needed. Play with it and spice to taste.

how deep can this sub play...

my plan is to replace the two RE SX12's in my hatch for two of these 8's to regain a little bit of hatch space. (my enclosure is eating up 1/2 of usable space now.)In their optimal sealed enclosure, how deep can they physically play? i have some songs that go as low as 28HZ and thats where my 12's come alive, but i've been steering away from that genre more and more,but still listen to some on occasion.I'm not expecting these to play as loud as my RE's , but i do want them to be able to handle that frequency if need be.i can deal with the loss in spl. but don't want to sacrifice the quality of sound.so then... largest i can go and still maintain deep bass output and keep the power handling within reason. im looking at the 4Ω versions and will be wiring @ 2ohms. my amp is rated at 900 into 2Ω so i will obviously adjust the gain very very low. if thats too much i could always rewire for an 8Ω load. (i do have another amp if need be, much lower power @2Ω)
Asked by: PQmodean
In their sealed enclosures these will easily reach 28 Hz in a vehicle application. As you said they will not play as loud at this frequency but they will work well for all types of music.
