Port size on box for Dayton audio 12"

Hey guys,

I'm designing a box for in my bedroom with a Dayton Audio RSS315HO-4 12" subwoofer using WinIsd.
I've now tuned it to 26hz but my port height is 4cm (1.57inch)

Do you guys think I will have problems when my port is so small? Will I get any port noise?

What is WinISD showing you for Rear Port Air Velocity (be sure you have set your system input power)?

I shoot for 25m/s or lower.

At 200w input power (probably not going higher as my room is pretty small and I'm going to use a 400w amp) It's only 13,5ms.
So if you think I should shoot for less than 25 I think im good

Thank you very much

Just to be sure, put your input power up to the full 400w. And don't forget to add the HPF, that will reduce air velocity as well.

At 13.5m/s you shouldn't have any problems.
