Would it make much of a difference that I use 2 ports instead of 1 single port, assuming that the tuning would be identical between the 2 vs 1? Is there more frictional loss making the enclosure less efficient? I want to do 2 slots on each end of the enclosure primarly for aesthetics.

 

If it's done right, there shouldn't be an audible difference ...

Go ahead and make it [img]smile.gif[/img] If it doesn't turn out the way you hope, try a new design ...

 

Usually it ends up to be more effort, but if you don't want to bother with slot ports and need more port area than what the single biggest port will do, then 2 ports can be better than one.
