i am building a ported box for 2 12" jl audio w3s and i was wondering is there a difference between slot porting and circular porting? Is one better for spl than the other. Please let me know, thanks.

There is no difference, as long as you achieve the same amount of port area with both...I prefer slot ports though, I feel they are much easier to make...

I prefer slot porst as well...
you don't have to worry about resonating port material, you can make the port shorter a lot of th etime, the port itswelf provides bracing for the box, and you can make better use of your enclosure volume.

slot ports usually give people more port area. easier to make too. my opinion.

what is resonate port material, i am new tob ox building and have never worked with ported enclosures before so sry for the lack of knowledge. Also, is 2.25 per sub enough for the 12w3s ill be using, i know thats about what jl reccomends but sometimes bigger is better. thanks.

I would just be worried about some material like PVC resonating with the output... ie -- sounding ******...
