i found an old post that was a very interesting read. it was originally about sealed cabs vs ported cabs but got into great detail on the ported cabs. i have a few questions about porting. 1. many bass playas have found rear ported cabs to have a tighter sound then front ported cabs. i know this is not "always" true but most of the time it seems to be the case. why is this? 2. ive heard that a front port results in more mid range. is this true?
