Dayton Audio ST255-8 10" Series II Woofer
Dayton Audio ST255-8 10" Series II Woofer is rated 4.2812 out of 5 by 32.
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.

Rated 5 out of 5 by from replacement midrangeI had a couple of Kenwood speakers that i purchased about 21-22 years ago when i was in the Air Force and stationed in Korea. One of my speaker's midrange went out about two years ago and I mistakingly replaced it with a PA (public address midrange) Well, the other midrange on my kenwood speakers went out and i called technical support. The Tech Support staff got me the right Midrange and I'm very happy with my purchase. I'm ready to keep my Kenwood speakers for another 20 years!

Rated 5 out of 5 by from Daton ST255-8 As An EV Replacement!I received a couple of EV Interface CII's boxes that had the woofers missing. After a long look for replacement woofers I found these. They are an actuall improvement to the original woofers!. Near matched for SPL, better FS than original, perfect VAS match and much more! The low end is so good I do not need the EV EQ to boost the low end now! These woofers sound very good and is a great replacement for the original woofers!DC Audio Labs

Dayton Audio ST255-8 10" Series II Woofer

Port Length/size for Dual woofer setup in a 2.7 cu ft box

I am looking at using these as replacments in a vintage dual 10" woofer speaker with a internal volume of 2.7 cu ft.What would be the ideal port length and size for this set up? I would like to get by with one port (stock is 2.5"D x 2.5"L) but I'm thinking 2 would be ideal.Thank you in advance.
Asked by: Mojo
There are several different ways you can do this. You can go with 1 5" port 4.68" long or 1 6" port 7.62" long.You can also go with 2 2.5"ports 2.34" long or 2 3" ports 3.81" long.In both cases the larger, longer ports will give you less noise or "huff". All 4 configurations will tune to ~48hz with an f3 of ~46hz. The drop off below tuning is pretty sharp so it might be a good idea to put some protection on them below 40hz or so. Should sound great

I have read that this is used in the Wicked One by Decaware. Does anyone know the internal volume of the sealed chambers in the Wicked One??

What is the f3 of the Wicked One using these drivers??Can this sealed volume be changed to a vented enclosure by installing a vent in the horn opening at the rear of the sealed enclosure??I would like to try them as a subwoofer cabinet (Wicked One) in a bass guitar rig.
Asked by: WTett
The WO as designed has an f3 of appr. 40hz with these drivers. The sealed chambers are between .8 and 1 cu ft depending on the baffle and how you mount the drivers. I have built about 75 of these myself and worked with a gentleman in Canada who tested at least another 100 configurations and can tell you that porting is a very bad idea. The horn loading side is very short and any disruption will be very detrimental to sound quality.It will work great for your application as is and will provide plenty of output. If you are less interested in total spl and more in musicality build the WO32 design. F3 is 32hz and output is smoother. Any questions you may have feel free to contact me or Bob from the Decware site. I doubt anyone short of possibly Don has more experience with these.

Why no frequency response/impedance graphs?

I see you have replaced that pertinent information with user reviews. Reviews are fine but not at the expense of needed specs. Don't tell me that the manufacturer didn't supply them. I get some of this from other sites for the same brands you sell.

what size port should i use in my cabinet 48''h x 12''w x 18'' deep #outside dimentions made from 3/4 mdf#.

I want to use two 10 inch woofers in each cabinet (not sure which crossover to use but I like the dayton silk dome 1 1/8 inch tweeters. what port size can i use I WANT SUPER AUTHORITUVE BASS. THANKS
Asked by: VITOB
This enclosure is about twice the size it needs to be for these woofers, but two 4" diameter ports that are 5" long will tune this to 37 Hz. I would recommend heavy fill in the enclosure.

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.
