[QUOTE="Buck, post: 8814227, member: 591582"] I agree with this as a general statement- ported boxes tend to peak higher in vehicles than their tuning. I have designed for people where they peak lower than tuning with ported boxes, but iirc that’s usually a more extreme system situation with a bunch of changes to the vehicle itself, and it’s fairly rare, from everything I’ve seen/heard. Most people tune low enough where cabin peak is above tuning, so very rarely have I seen ported peak below tuning, but it does happen. I’ve had someone tuned at 29-30 hz peak 1-2 hz below that tuning. [/QUOTE]
