Dayton Audio ST210-8 8" Series II Woofer
Dayton Audio ST210-8 8" Series II Woofer is rated 4.7778 out of 5 by 36.
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.

Rated 5 out of 5 by from Sub drop-in replacementThis woofer worked very well as a drop-in replacement for a Tang Band W8-740P in a PWK enclosure. The cutout-size and screw-hole pattern were nearly identical, and the quality of upper-bass notes are much more articulate, punchy and tight. The lowest lows are not as pronounced (below 40Hz), but are still present. If you are looking for a more musical response, get this woofer while it's on sale for $46. I have it set up for home audio use.

Rated 5 out of 5 by from Real nice!This is the second pair of these speakers I have purchased. I listen to my music LOUD...and these speakers do not disapoint...My system comprises of a Crown XLS 1000 driving a pair of Pyle PDBT68 Titanium tweeters, a XLS 1500 driving a pair of 8" and 10" Dayton series II woofers, a 15" Velodyne sub all controled by a new Carver CT6. Both the 8" and 10" series II's really put out quality sound. Highly recomended.

Dayton Audio ST210-8 8" Series II Woofer

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.

Was there a prior series to the Series II? I have a Dayton ST210-8 here 6-7 yrs old and was thinking of buying another to match up with this one but wondered if I had on old model with different specs than the Series II. (not sure if mine is series II.)

Asked by: Greg49
The Series II woofers have been available for more than 10 years and there are no predecessors. If you can, email a few pictures of your woofer to tech@parts-express.com and we can try to identify it.

Bought and installed this woofer in a 0.8 cubic ft enclosure with a 1.5" diameter port that's currently 6" long. Low end seems very thin and wondering if port is too long. What would a good length and tuning frequency be for this port to improve the bass?

Asked by: lorcan
I would highly recommend changing both the diameter and length of this port to help with the bass response. Right now you are tuned to 30 Hz which is not only a bit low for this woofer, but a 1.5" diameter port will have chuffing power compression problems even at low volume levels. I would recommend no less than 2.5" diameter for this. We have a single flared, press fit style port that would work well and raise the tuning frequency to about 43 Hz, it is our part number 260-478.

i want to use 2 of the st210-8 in each enclosure is possible to vent only one of the woofers has anyone done this

Asked by: TN. WILLIAMS
It is possible but not generally recommended. These will provide the best results in a vented box, sealing one woofer will not benefit you.

Asked by: TN. WILLIAMS
This volume is actually about double what both choices would like to have. The Hi-Vi has a lower F3 however which would be a better performer on the low end achieving an F3 of 60 Hz.

Will these replace JBL M#408g factory woofers?

Asked by: ttalb85
The Series II woofers are quite robust and fairly versatile. I recommend them on a regular basis. However, we do not have any kind of cross-reference by brand, model, or anything of that sort. If your JBL woofers were 8 ohm, and the cabinets will physically accommodate the Series II woofer, I'd recommend giving them a try. As far as being a "direct" or "drop-in" replacement, I'm afraid I cannot guarantee that it would (or would not) be such.
