The PSA 15S is a powerful sub. As much research as you did, is box size the only reason you choose a downward firing sub? Front firing is more popular among audiophiles.
When I had one, I had a hardwood platform under it. The deep carpet in my living room did not work well with mine. I've seen discussions about the optimal surface to fire against. Are you going to place yours on a custom surface?
The driver orientation should have no/little effect on the performance. There could have been other variables in play.
