I don't have any build pics of mine yet, I started over a year ago, but the problem is I already have a reasonably capable sub in a 15" RL-p'd sub similar to another sub builders mondo ported AS-15. I'm using one dual-4 ohm driver wired in series for 8 ohms load on my ADA-1200 right now, giving it a restrained 600 watts total.
If this sub didn't exist, I'd have put a lot more enthusiasm into the new project, but so far, I have about 50 percent of it done - I still need to route and mount the two drivers to the front baffle, install two internal window-style braces in the enclosure, a couple of braces to tie the front to the rear, and debate whether to install my amp in the box or go outboard. Here's a pic of the existing single driver AS-15 copy I built.
Notice my RL-p has no logo... neither does it's sister that will join it in the new box.
