Dayton Audio ST255-8 10" Series II Woofer
Dayton Audio ST255-8 10" Series II Woofer is rated 4.3235 out of 5 by 34.
Rated 5 out of 5 by from Great Subwoofer driverI bought this woofer to replace a worn 10" driver in my subwoofer and it sounds better now than it ever did! Love it!

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. BTW the "direct energy control" function of the 501's, really work. I thought it was just a gimmick.

Rated 5 out of 5 by from Nice sounding Woofers!I had purchased 4 of these Dayton 10" Woofers and 3 of them arrived with the same assembley defect. However Parts Express was outstanding in their customer service and replaced them very quickly. I figure it was just something that happened during part of this production run, as they are highly regarded Woofers.This is a great place to do business!

Rated 4 out of 5 by from Very good replacement woofer for EV Interface C (s4)Used as a replacement woofer in my 1983 Electro Voice Interface C (series 4) speakers. I am pleased with the speaker performance. The EVs now sound great. The only downside is the external speaker surface coating is a bit sticky.

Rated 5 out of 5 by from Superb sound -- better than original woofersThese went into an old Lafayette 3002 Criterion (made by ESS) speaker system -- a two-way with a Heil tweeter and a 2,000 hertz crossover. These are heavy, obviously well made woofers. The original woofers rotted out and were replaced about 14 years ago. Although the sound wasn't bad then, I suspected that it would be better with replacement woofers, and I was right. With the new Dayton woofers the sound is superb. The bass goes down strong to 35 hz. and is audible well below that. But the beautiful thing about the new system is the mid-range, which sounds just right, with great transient response. I judge speak systems largely by how well they reproduce piano sound, and with good source material, the piano sounds like a piano. In short, I am very happy with these woofers.

Rated 5 out of 5 by from Often overlooked subwooferI bought this speaker about 5 years ago to replace a blown Carver sub and it still sounds great. This is a very music friendly sub If you are a bass guitar fan then this sub will please. It doesn't thump so it's probably not the best for rap or hip hop unless you have some form of bass boost. It does replicate explosions quite well and has no problem shaking the walls with a 200 watt rms amp. It has a flat range that is very usable through 250hz which makes it ideal if you are planning on pairing it with little main speakers that don't have much output below 200hz.

Dayton Audio ST255-8 10" Series II Woofer

OK thanks for the help. Just to be sure: I need the 3" dia port at 1 7/8" length and an extra 2" dia port at 1 7/8" length. Correct? Before I start drilling holes. :)

Asked by: mars_volta
We have slightly mixed up answers since the port dimensions from the original question changed. You only need one port. A single 3" port that is 2.5" long will give you the proper tuning frequency.

Correction to my question. I re-measured and got about 32.75 h x 10 d x 11.75 w internal dimentions. The port is 3" x 4.75" long. If I cut the port to about 1.25" will this tune the box up to about 50 hz to match the woofer? Thanks

Asked by: mars_volta
Cutting the port to 1.25 will bring the tuning up to about 55 Hz which is a bit too high for this woofer in that volume. I would recommend a length of 2.5" for a tuning frequency of about 48 Hz.

Hi, I just purchased a pair of JBL 4800 speakers that have these woofers. They sound good, but I would like to optimize the box. They are about 38" tall, 16.5 wide, 15.5 deep with about a 2" port on the front. Thanks!

Asked by: mars_volta
A single port will not tune this airspace to the best frequency. It would be better to add a second 2 inch port tube each of which would be 1-7/8 inches long. That tunes to 34 Hz and the 3 db down point would be 35.

What size port is best for a vented 0.9-1.0 cu ft box with this woofer?

What size port is best for a vented 0.9-1.0 cu ft box with this woofer?Looking to use 4 of these in my car powered with 1000 RMS at 2 ohms.
Asked by: SpencerK
IT looks like a tuning frequency of around 50 hz will provide the flattest response in that airspace. To tune to that, use a 3-1/2 inch diameter port tube that is 8 inches long.

I NEED TO RE CHOOSE THE WOOFERS PERHAPS

WHAT WOULD BE THE BEST WOOFERS, KEEPING COST IN MIND FOR MY ENCLOSURES FOR MAXIMUM PUNCH? 12W X 48H X 18 DEEP. OUTSIDE DIMENTIONS OF 3/4 MFD. THANKS
Asked by: VITOB
Why are you stuck on this enclosure size?WHat type of setup are you using these in?The more information the better.These are great woofers if your looking for high output musical/realistic bass.These woofers remind be of the awesome bass Altec Valencia's have, but a notch up in the clean/transient department-but have the same "soul".If you just looking for "boom" look else where.They really work better in smaller enclosures. This is what really makes them quite unique-as it's hard to find a quality 10" woofer that works up to it's potential in a smallish enclosure, and not loose extension or output.
