not much I dont think. Leave it at 26... those low notes must feel good //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
2) How many DB's will you hit?- Somewhere within the audible range of sound is your answer. Don't ask questions with infinite variables that are yet to be determined. Deleted on sight.
You most likely will not notice a difference. 4Hz is not a significant change. For SPL you would tune higher, in the 40's, but not for a daily driver. If you want a new box go somewhere closer to 35-40Hz.
no telling...we sometimes gain a few tenths dropping/raising tuning..sometimes nothing. test and find out //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
