Dayton Audio ST255-8 10" Series II Woofer
I have a pair of cerwin vega dx3 speakers 1has a blown woofer they say 8 ohm 125 watts would this be the best choice for a replacement speaker and should i replace the woofer in both speakers or do you suggest something different. Thanks
These are a great replacement for those woofers. We do recommend replacing both, if one woofer is bad the other is probably not too far behind it.

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. :)
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
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!
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.
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.
