Hi, I've got an Epifani UL310 that I like in most respects, but for me, the low end is too extended into the deep bass. At the same time, it is shy in the low mid/ upper bass region which is something I'd like to get more of (more punch) . My thinking is that by plugging the tuned port, I might be able to reduce the very low bass while perhaps gaining a bit in the low mid /upper bass region. Is this a reasonable expectation? I ask because it's an awkward port to plug without doing permanent damage to the cabinet- it's a large rectangle cut into the baffle which borders the lower corner of the box. Worth a try? Or should I just move on? All opinions welcome. Thank you.
