[QUOTE="hispls, post: 6842360, member: 614752"] If you have a slot port with a wall as one side, the wall acts to extend the port (this can happen outside the box too depending on placement). Technically if you want to split hairs, picture a 45 degree angle from the top of the port to the box wall...that's what the system "sees" as port volume/length. 5hz difference in tuning is a noticeable difference. The loss of some internal volume will also affect low-end extension and response. I have a box tuned to 33 and I think it's a good middle ground with low end extension and some output in the higher stuff. Honestly the largest factor in how it's going to sound is the vehicle anyway. Really depends on what you like. I've tuned everywhere from 45 to 25 and I even go through phases where I'll miss one or the other. [/QUOTE]
