Help with port?

[RAM_Designs 5,000+ posts]

Assuming you're using 3/4" MDF, you're looking at 8.23ft^3 before sub and port displacement, so you're not looking at anything close to 8ft^3 after all displacements. Since you used 8ft^3 to figure out your port lengths, your tuning is higher than expected. With the second port, you're actually looking at ~7ft^3 with a ~43hz tuning after it's all said and done. Definitely not something you'd want to have to listen to on a daily basis.

Your port area is too small in that case. You just need a bigger box overall. Something like 10-11ft^3 before displacements will work much better, but I doubt you have all that extra room.

You could try to do aeros to save some space.
