I know i've been posting crap about custom boxes all morning, but im curious....hehe....anywho, Do the port tubes make a big difference, Will PVC piping be the same as this expensive 20$ Lighting Audio port? As long as they have the same diamiter and length?
If you get one of those super-flared port ends like in the kits Adire used to sell you can get away with a smaller(and thus shorter) port. I'm not familiar with those Lightning ports, but if they're anything like the Adires and you're short on box depth they might be worth it.
