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 14.
Rated 5 out of 5 by from Awesome sub!I'm using this sub in a "full Marty". A large ported box tuned to 17hz. I'm powering it bridged with the behringer 3000dsp. What a combo!I have a large living room and open kitchen. One of these does the job for me, but there's always opportunity to get another!

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!

Would this driver work in a downfiring setup? Speaking mostly to cone sag and long term survival....

Where is this driver made? I see the Titanic MK4 are made in USA and proudly display that fact. I don't see anything indicating country of origin on this driver.

Asked by: Haoleb01
This subwoofer driver is made to a high standard of quality in a medium-volume speaker production facility located in Taiwan, which ensures each unit gets a high level of attention to detail during assembly and testing. Reliability and consistency of our Taiwan-sourced drivers have both been excellent. The country of origin is indicated on the product label and is also printed on the product box.

Frequency response says 20-500. But the frequency graph & impedance graph show it producing sound well over 1k. Whats the deal with this whole frequency response thing? Why would it not say 20-2k etc.. if the graph shows it reaching that high

Asked by: Dr Smith
They claim 500 Hz because this is where the response becomes non linear. Generally its not a good idea to cross an 18" driver higher than about 800 Hz anyway, but in this case 800 would be about the upper limit of useable response depending on application and crossover slope.

What is the displacement volume of this driver that I can add to my calculations?

Asked by: Gibroni
This drivers displacement is 0.39 cubic feet when front mounted and 0.45 cubic feet when rear mounted.

OK......I am sold by this driver. May I know whats is the Best net Internal sealed box for this beast Placing into account the driver displacement and how low can I reach in Home theater???? Thanks In advance.

Asked by: pROJECT1
The recommended sealed volume for this woofer is 3 cubic feet net, assuming 0.39 cubic feet of displacement for the woofer. This provides an F3 of 40 Hz and in room response into the low 20's.
