I think either setup could win in terms of overall peak SPL, just depends on exact tuning and setup. If you want a demo machine, a wall is probably going win that battle most of the time unless it's built like crap. It's blasting right in your ears and filling a lot smaller space, so things like hair tricks and floating bottle tricks would probably come easier. However, a wall isn't as easy to change/modify if you're not happy with the results. I have 4 10's and went from a 5 cu/ft ported box to a 15 cu/ft 4th order by just pulling one out and replacing it with the other. If I had done a wall like I originally planned, it would have been a ton more work. Both boxes required removal of my back seats, the 4th order is just much bigger and it crushes the ported box on the same power in pretty much all aspects. I have cheap woofers for now but in the 4th order it still kills the lows like 15's or 18's, once I get some better woofers I am planning a 4th order wall. Just something to think about, if you really love the lows. I see your location says Indiana by the Colesium, do you mean the one in Fort Wayne? If so I work just down the road from you.
