A well designed ported speaker sounds every bit as “tight” as a sealed speaker. It is a function of qtc and group delay. It is not a matter of sealed v ported, but how the designer has tuned it.
You really need to look at your room. Without running REW or the equivalent, you will never see the likely 30db varience you have in bass levels at your listening position. Small changes in speaker and listening position can make major changes in these peaks and nulls. You also need to measure your decay time. If your decay time is long, it will only further emphasize standing waves and bass bloat. Treating the room (look at GIK acoustics which are inexpensive and will make recomendations if you send them your room information) will run under $1000 and do far more to address what you are experiencing than chasing different speakers.
Digital correction can also be used (i.e. Mini DSP), but I would always start with placement and room treatment becore applying DSP.
