Can't speak to the Orions. I had a decent set of JBLs which sounded great...or so I thought. lol These 5s are impressive, and the PWX 8s really do an impressive job. I've got leaky doors due to the design from the factory. The door panel doesn't pop on or bolt in. It slides down into channels, so when the panel is actually on, there are six 1" x 2" channels still wide open which I have yet to figure out how to seal. The doors have CLD, CCF, MLV, 1" thick fiberglass ceiling tiles sealed in plastic, 3/8" MDF filling the large holes in the door using butyl rubber sealant, and I have open cell foam behind the speakers in my homemade door pod (the PRV location is sealed and the PWX is vented into the door cavity). With the sub turned off via the HU (but 8s still crossed over at 80Hz with a 12dB slope) I get more bass than any factory system I've heard, even when they had subwoofers. Beats even the 8" subs I had installed in the doors until I could get these bought. lol Yes, I was desperate.
