I'm ditching my slot port enclosure I used with a 15" sub. The sub and port were both firing at the hull which caused too much flexing. Due to the size of the box, I could only fire the sub and port towards the hull.
I'm rebuilding my box with PSP or Aeroports to reduce the overall size of the enclosure, and allow me to fire the sub, ports, or both into the cabin. I recall a few members here who have done both with a 15" sub. I was wondering how much different the outpout is? And any opinion on sub/port firing direction (i.e. sub to the hull, port to cabin)
