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 4.9375 out of 5 by 16.
Rated 4 out of 5 by from Good Value & Excellent CompanyI purchased two of these for the pair of subwoofers I built. I put these in a slot ported cabinet with 7.672 cubic feet internal volume. So far they have been excellent drivers. I am very pleased with the final product. I really did not expect an 18" speaker to sound so clean and punchy as they do. The quality of the speaker seems to be quite good for the price. I did have some issues with the drivers arriving damaged in transit but parts express was easy to work with and quick to send replacements. I do believe the packaging could benefit from being beefed up.I will say the cone is quite fragile. When installing the screws to hold the driver into the cabinet I dropped my small T handle hex wrench and it put a small dent in the driver about the size of a pencil tip. Certainly not as durable as the ultimax cone.Regarding sound quality- I know this is very dependent on system and cabinet but I have been very happy with the amount of bass these drivers will produce without flinching. I was concerned that a speaker of this size would be good for HT use but not so much music use which is more important to me. Let me assure you those concerns were not well founded.I have spent quite a bit on the mechanical cabinet design and construction and would be happy to share my efforts upon request. I think overall this driver is very good quality and an excellent value. I would give 4.5 out of 5 stars if possible because while very good it is not perfect.

Rated 5 out of 5 by from Perfect Home Theater Sub.I'm using two of these in a Marty Cube build. All i can say is there awesome. These will make pictures dance on the wall. My 65 inch wall mounted tv shakes with the bass. I seriously can't think of one con for them. Quoted from my friend " I can feel the air being pressurized". I've had many setups and with these i feel no reason to upgrade. If i do i will be just adding more of these subs. Music and movies sound just sublime through these.It doesn't matter if its the latest blockbuster or old school Metallica.Great work Dayton!!! Last sub I'll ever buy!!!

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!

Looking to do a cabinet of around 6 cuft. Want to do a slot port. How big does the port need to be to be tune around 25hz

Asked by: JStelecom
A port that measures 2"H x 18"W x 28"L will tune that volume to 25 Hz.
Answered by: MattP

I have a 7.5 cubic foot box with 2 three inch flared ports 11" long - for a 15 Hz tuning - using a SPA500 plate amp.  If I upgrade to this 18" driver in the same box, should I change the ports - and will my current plate amp work OK? 

Asked by: kcburnes24
That volume and port size is actually a 20 Hz tune. I would recommend upping the ports to 4" dual flared at minimum but they would need to be 17" long each in order to maintain a 20 Hz tune. Otherwise this combo should work well.

I wanted to know how much huff and puff I will get if I Put this into a 6 cubic foot net internal with the 6 in precision ports flared port 17 inches long. My sim says that I will get around 46 m/sec of port velocity. Will I get chuffing?

Asked by: HonestAbe
According to my sim the velocity is closer to 25 m/s and that doesn't account for the flared ports. I doubt you will have noise problems.

I see that the db is measured by 2.83v/1m... Can you tell me what the db would be if measured to 1w/1m?

Asked by: Nick856
The SPL rating at 1w/1m would be about 89.2 dB.

If this driver is surface mounted--not recessed--how thick does my speaker grill frame need to be so that the fabric does not touch the rubber surround? Thanks

Asked by: Dan_K
I would recommend a grill that is at least 2" thick to allow for surround clearance.

Sanity check from reading previous questions and answers, but if I'm not mistaken, 3 of these in a 22-ish ft enclosure with 6 total 4 x 17 inch ports would work well? All with their own SPA1000 and own 15amp circuit.

Asked by: wsmc831
Yes that alignment should work well.
