Enclosure design

Hello everyone,
I have a 5.25inch, 25w subwoofer driver. I wanted to design an ported wooden enclosure for this driver. Can anyone give me the best dimensions of the enclosure.
I tried to get the dimensions from the online tools. But it was very difficult for ....me as it was asking to enter too many inputs.
I'm still a beginner in this Audio related stuffs. So please help me guys.
 
Without Thiele/Small params you either need to measure them (not easy), get a new driver with the data, or recreate the original enclosure on the assumption its well matched to the driver.

Or simply guess based on a "similar" driver - not ideal though.


You can try to identify a similar driver by using online tools to try out the enclosure volume and port size with
a library of drivers - if one works well with enclosure details matching your old enclosure, that's likely to be
a "similar" driver.
 
I have made a huge TL, about 50 l, bifurcat3d at the end, well, I made two 🙄
So one day I tried a cone like that, and I put it reversed(with the magnet outside) and even if the diameter did not fit, ' cos it was for a 6.5", I really appreciated the little cone doin' subwoofer things. But that way would be a BIG NO- No for many reasons :rofl:🙁

So you may vary from the very small to the big box
BTW I remember I was testing those 2.1 systems with tda 222something so 2-3W :forbiddn:
 
Nuvve Ikkada?
You get old Philips 2 way speakers in cabinet in scrap market for about 100 Rs.
Don't bother with this.
If you insist, use MDF board, 10 inches wide, 14 inches tall, 15 inches deep, with a tweeter if you feel like.
2 bass reflex ports, about 2 inches hole.
Get the MDF, which should be 1/2 to 3/4 inches thick, cut by a shop which has a table saw.
Holes by jigsaw or whatever.
Paint with any paint you feel like.
Alternately, try PVC foam board, same price, no fear of moisture or termites.
Glue edges, use nails or chip board screws to hold it together.
White PVA glue, for example Fevicol.
I assume you are in India.
