Dayton Audio ST210-8 8" Series II Woofer is rated 4.7895 out of 5 by 38.
Rated 5 out of 5 by from Good replacement for old equipmentThese were a good replacement for 30(!) year old Acoustic Research speakers. As a bass player, I'm able to hear the entire range of music at "background" dynamic levels.

Rated 5 out of 5 by from Very HappyMy wife brought some Bose 501 speakers home from a garage sale because she liked the grill covers. They will fit in with our retro MCM style, so that is the only way i can get speakers in the house. One woofer was missing and the other's surround was falling apart. The 501's and the Bose line in general doesn't get much credibility in the audiophile world, so I took the opportunity to upgrade the main woofer with these. The cabinets seem sturdy enough to warrant keeping. I tried the Dayton Audio designer series first, but they were a tiny bit to big in diameter to fit in the cabinet, which was too bad since the range on those looked like a good fit with the crossover's in the 501's. So Part Express was great about letting me return those and I went with a more expensive speaker (Series II) and double checked the measurements. These dropped in fine and the magnet is huge and heavy. I have no idea what 501's sounded like originally, but mine sound nice and are going to be awesome for any party because the bass really sounds nice and rich and tight at high volume.

Rated 5 out of 5 by from Thump a plenty!Put two of these in parallel in an old wedge cabinet and coupled with a hi powered bullet tweeter I now have a pretty good low profile drum wedge

Rated 5 out of 5 by from These are woofers!Replaced two old 10" woofers that were oversized in cabinets cut for 8". These new 8 inch speakers have so much more response I now back down the lows. Powered by a vintage Sansui (80w rms per) , they take it well without float. At low volume, they are just as clean.

Rated 5 out of 5 by from Best Purchase EverThe speaker that I bought was the best replacement for my Technic rock system that I had purchased in 1995.

Dayton Audio ST210-8 8" Series II Woofer

What is actual overall diameter of this speaker? The specs say 8.22 inches but I just want to make sure. I am looking for a speaker that has EXACTLY 8 inch overall diameter. I got some Goldwoods that are supposed to be 8 inches but are actually less.

Asked by: RandyPLD
The diameter of the frame of this woofer is in fact 8.22".

I have these in .75 sealed cabinets.I notice that is right in between sealed and vented recommendations. Should I vent them? If so size and length? Thanks. John  

Asked by: john88
I would recommend using a vented enclosure with a 3" diameter by 8" Long port with a F3 of 55 Hz.

I need to replace a woofer in a Energy 22e speaker. They are 8" and 6 ohm. I don't see anything of that combination. Can I use 8 ohm or 4 ohm instead?

Asked by: raadams130
The only way to definitely get the same performance as the original speaker is to replace the existing woofers with an original driver. (If you look around online, you might be able to find one even if the original is not available from Energy.) If you use a replacement woofer with 4 or 8 ohm impedance, you will end up with something that makes sound, but it may not sound the same as the original speaker, because the crossover network of your speaker is designed to get the best performance from the original driver. If making sound is all that's important to you, then you could probably substitute a 4-ohm or 8-ohm woofer and have working speakers.

Could I use 2 of these woofers with the dayton RS28F tweeter in a hi SPL MTM configuration. I like the way the RS28F sounds with crossover at 3kHz. Will these woofers play clean with crossover at 3kHz? I'll be using a MiniDSP.

Asked by: Shoe
These woofers do not have a very clean response up to 3kHz, and I would not recommend crossing an 8" much higher than about 2kHz anyway. You might want to consider something like a pair of the DS175-8 woofers instead, which will cross at 3 kHz and still provide a decent sensitivity.

I'm want to build a box with the measures of an Adan s3x-v with this woofer,. I don't know to much. Wondering myself if it would work perfectly? Does the crossover of Dayton Audio XO3W-375/3K 3-Way Crossover 375/3,000 Hz can work with this woofer? Thanks.

Would this be good driver as a car subwoofer in a .38 cubic foot enclosure, driven by a 200 watt Rms amp?  I'm looking for a solution to provide a musical, not boomy sub in a smallish Subaru Xv Crosstreck (hatchback).  I don't have a lot of space...

Asked by: SteveXV
This is an excellent woofer but not the best choice for your application. I would recommend looking at the Dayton RSS210HO-4 instead which will work very well in that volume.
