Dayton Audio RSS460HO-4 18" Reference HO 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. 

A knock-down 4.0 cubic foot subwoofer cabinet built specifically for the RSS460HO-4 is available here. Save 50% off the price of the cabinet when you buy the cabinet and RSS460HO-4 subwoofer (at regular price) together in this package.

Dayton Audio RSS460HO-4 18" Reference HO Subwoofer 4 ohm is rated 5.0 out of 5 by 13.
Rated 5 out of 5 by from Exceptional subwooferPut one of these beasts into a 10.2 cu.ft. ported enclosure, tuned to 19 Hz powered by a Yung SD500 (no boost) plate amp. Wow! Unbelievable output and clarity. This thing handles the cannon shots from the Telarc 1812 overture (Erich Kunzel- Cincinnati Pops,1979 version) at quite high volume. Star Trek - Into Darkness, no problem! I built this sub to complement my Hsu VTF3-Mk3, which is no slouch in it's own right. The Dayton Audio driver is built like a tank, I expect it will provide many years of awesome home theater and music. If you have the space to use a very large enclosure with this unit, I would recommend doing so to get the best out of it.

Rated 5 out of 5 by from WOW what a Subwoofer!I am using this in a 4 cf sealed enclosure that I bought from DIY Sound Group with the 1000W Dayton Audio Plate Amp and I was figuratively and literally blown away! At my house, this thing is called the "Sledge Hammer!" This is a very musical driver, even at high gain the different bass notes are very distinguishable. I was concern that this drive may not be fast enough to keep up with my front mains (Monitor Audio RX-8s) but this thing had no problem keeping up with the mains while playing Metallica's Motorbreath!I assemble everything on a Friday night and wasted my entire weekend playing everything from Wu-Tang to Beethoven. When I told my wife I was going to build a subwoofer, she just rolled her eyes but after I played Moonlight Sonata with and without the subwoofer, she was very impressed.Even as a home theater sub, this thing delivers!My only complaint is that this thing is heavy which makes it difficult to mount...and even that is not a real complaint.

Rated 5 out of 5 by from Rebuilt My Old Velodyne ULD-18 SubwooferMy 24 year old Velodyne ULD-18 self-destructed (with multi-pieces of cone on the floor), and Velodyne told me that they have no parts left and don't support the speaker. I searched the Internet and found the Parts Express website and one very satisfied customer commented on how he resurrected his broken ULD-18. I called Parts Express and they responded that in respect for the privacy of their customers they would only contact that happy commenter and ask him to contact me. He contacted me immediately and sent several pictures of the process of installing the Dayton Audio 18 inch driver in the Velodyne cabinet and power it with the Dayton Audio SA-1000 amplifier. I purchased that combo from Parts Express, did an installation and balanced my whole audio system with my sound meter and I believe things sound better than originally with the Velodyne. AND the Dayton Audio driver and amp cost less than 25% of what I paid in 1989 for the Velodyne!!! So far, couldn't be happier!

Rated 5 out of 5 by from Awesome HT PerformanceI currently use 8 of these in my home theater. In short, the performance is outstanding, especially considering their cost. I easily achieve flat in room response down to 6hz in my room so full bandwidth reproduction is not an issue. I have 2 drivers in each cabinet in a dual opposed configuration. Would definitely recommend to others.

Rated 5 out of 5 by from Best out of 3 and my last!This now makes my 3rd Subwoofer I have owned.Years ago I owned a Velodyne ULD-18, the woofer blew and it could not be repaired, it was a servo-type set up, special amp and woofer. I put the cabinet in storage and bought an ACI-Maestro which I have been using for the last 8 years. Because I needed to do something with this Velodyne cabinet and I knew it would be easier to sell the ACI and matching amp than the cabinet I took the chance hoping I would not regret it and sold the ACI and then I purchased this driver and the matching Dayton Audio SA-1000 amp.My Velodyne cabinet is very nice looking, 1” MDF wood, 6.3 cubic feet and sealed. I added some internal bracing and more poly-foam to the interior sides of the cabinet and with just a little modification to the hole to make a little bigger, the 18” driver went right in and the screw holes all matched up, and I DO NOT regret it, this set up is awesome!The amp with it parametric EQ is a very nice fine tune feature and this woofer is solid, tight and goes very deep, even at low volume! I am very happy I did this move, the cabinet size is a little bigger than the ACI, but this sub is more powerful and better sounding! I am hearing low notes and tones I have never heard before and it is on a concrete floor!It’s like the cabinet, driver and amp were all made as a matched set!

Rated 5 out of 5 by from Best value for a large subwooferI found a 55 gallon drum (not the metal ones) made out of corrugated fibers. It has about 9 cubic feet internal volume, or less and only costs $40 bucks off of CH.com.Taking two of these drums, I tuned the F3 to around 30 hz ported with 6 inch diameter ports.The graph in Bassbox pro shows a nice 3-5 db gain in the 25-40 hz region. And an estimated 130+ db at 1,800 watts.I am pushing 2 of these with a Crown XTi2002 - 2000 watts into 2 ohms. The bass will not even distort, ever, even at 6 hz. Yes, 6 hertz! The only qualm with this 18" is the 89.2 db sensitivity. But to get such a nice frequency range, the sensitivity had to be lowered as so. Overall, I'd recommend this speaker for true audiophiles. And always buy a pair. I would recommend at least 300 watts RMS per sub. Go for a ported box if you got a big place and you will be astounded by the detail and dynamic headroom. A VERY WELL CRAFTED SUBWOOFER! I'd recommend this to anyone who has plenty of power.

I put the parameters for this driver into WinISD Pro, with a 4 cubic foot sealed box. If I put enter 900W power, then WinISD shows that XMAX is exceeded below about 39Hz. Does that mean the driver will be damaged with 900W @ 20Hz in that enclosure?

Asked by: Newnumber6
I cannot vouch for WinISD but BassBox shows excursion is fine with 900 watts all the way down to 24 Hz in 4 cubic feet. Even if this is exceeded, it is just the linear Xmax number, the cone on this woofer is traveling quite a bit farther before mechanical damage is an issue.

I am looking to build two of these drivers into a single cabinet the cabinet will be a corner design with forward facing drivers. Because of the corner loading I am wondering if I should go with a sealed 8.5 cu ft or a 15.5 cu ft ported?  7,500 cu ft room

Asked by: RayD60
Either design will work and work well, it boils down to personal preference. The sealed design will play higher in frequency to match with a set of mains, so if you have small mains that require a higher high pass filter this may be the way to go. The ported enclosures will have more 'authority' at low frequencies, so if this is dedicated for movies this may be the way to go.

What would be the dimensions of a good ported box for this sub? I have the sub and a Dayton 1000watt plate amp in a ported down firing box I built and it doesn’t sound as good as I hoped. I am planning on building a new ported box but wanted to go with

Asked by: alphanut
I would recommend 8.7 cubic feet total with a single 6" diameter, 18" long port for a tuning frequency of 20 Hz. Our 6" Precision Port would be ideal for this application.

I have a build I'm doing with sub firing up and port firing out front side, port is Lshape port 51/2" by 251/2" wide x lengths of 22" then 22" up and out front side. at 6ft^3 without ports calculated in. would this sub work well in that enclosure.

Asked by: spur31
It will work, but it probably won't sound very good. Assuming the volume is after port displacement, there is a huge peak between 40 and 50 Hz with an enclosure tuning of 35 Hz. It will get loud, but will not play very low. I would recommend dropping the port from 5-1/2" to 2" to drop the tuning down to 22 Hz.

Does this driver come with the hardware to mount or will mounting hardware have to be purchased desperately?  If they have to be purchased separately, what is recommended?

Asked by: LannyBudd
This driver does not include mounting hardware. I would recommend our 1/4"-20 TPI cast frame mounting kit.http://www.parts-express.com/cast-frame-1-4-20-speaker-mounting-kit--260-778

Opposed, side-firing

Would two of these work good in an enclosure like this one?http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-766I don't own these yet, but as a side project to my current one, I was thinking about giving them a try.Thanks!
Asked by: Mr. Bitchen
Any driver that will work well in a sealed enclosure will work as dual opposed like this.
