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.
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

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.
The specification sheet for this speaker is located along the right-hand side of the page, under the "Manuals/Resources" heading. I've included a direct link for your convenience:http://www.parts-express.com/pdf/295-110s.pdf

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.
There are a number of forum thread strings that you can search for the details on the build of the Wicked One. The project is very complex and requires advanced math, design and construction techniques. Individual drivers, based on their T/S parameters, are often better suited to ported or sealed enclosures. Horn loaded are typically used for sound reinforcement for high SPL and controlled projection. On the other end of the spectrum, sealed with a total Qts of .707, or even more critical .505 yields the most accurate bass - not withstanding certain brilliant designers that manage to bend the laws of physics. For a beginning project - access your goals. A good cabinet with plate amp, ported or sealed will make for a good sub. Consider the volume of your room. Rigidity of the walls, wood or concrete floor - all these interactions effect the performance of the driver ultimately. Click the SPEAKER BUILDING tab up top, then the WOOFER SELECTION GUIDE to the right. You will find most drivers listed with suggested ported and sealed enclosures... From there, you can also use the T/S specs and plug them into a box calculator to see how you can vary the performance of the system... Hope this helps...

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.
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.
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
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
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.
