Hi ya guys I have four Wharfedale Delta 218B dual 18" subs and i've been using them for years and like them but they struggle with very low bass so I was thinking about taking out two ports in each driver chamber and then sealing up the ports and changing the drivers with RCF L18P400 drivers instead. I can't afford subs with lower bass so would taking out two ports and then sealing up the front holes of the ports enable the bass to be deeper? Or could I just seal up two ports without taking the port out?
Here are the subs in the photo below and as you can see they have four ports per driver which are big and not very deep so regardless of what the specs say they're about -3db at 50hz.
