I had a narrow face ppsl. It was the test bed b4 I plunked down the cash for 4 x 18's. That box was maybe 20" wide, it had 2 x 12" rockford fosgate subs, and was maybe 36" deep. The slot port was on the side running top of box to bottom, but was almost the length of the box. If you want a ported box that's tuned to 30hz or below, and you move a bit of air (dual 12's with 4mm xmax), it is tough to have a large enough port that's long enough to fit in the box. But, you could do a passive radiator.....

What did my 18's look like ?
Well, I had a sheet over it.
It was so big that people never suspected it was the subs.
They'd stand in front of it and say "Where are the subs?" thinking there is a box thing maybe the size of a velodyne box. But the 4' wide x 24" tall x 36" deep (2 boxes stacked one on the other) is huge. I'll see if I can post some pics this weekend.

Well I finally started cutting plywood. It took me a while to get going.
Well being new at wood working I have a tendency to over think things. I bought a router table extension for my table saw and thought a 45 Lock Miter Router Bit would be the perfect way of joining the corners without showing an edge. Well I learned all about tear out. So I gave up on that. So now I am using butt joints. Maybe some pics next week when I start screwing it together.
Any assembly hints?

premium glue and clamps. (screws always help)

Nothing else is really as important and most of the joint stuff is just overkill extra wasted time.

Any special glue?
I am planning on painting them. I want the corners to be good. Need to find out how to seal the ends of the plywood so the paint will look good.

Man those butt joints are ugly!

At one time I made a pair of PPSL with a centrally located slot with a 'V" shaped grill that looked way cool.
