Probably not, but there's no magic to it. Just a two driver ported pox, either 4th or 6th order, and the manifold as small as is practical.

You may need to do some more searching.

PPSL is a way of confguring two drivers in order to achieve some reduction in distortion (two drivers inside a plenum facing back to front). That is all it is.

You will still need to decide whether you want a ported cabinet or a vented cabinet. There might even be a horn loaded configuration. PPSL can be done with either. If you want a store-bought version that you could copy, there was one made by Electrovoice

Again, do a search here and elsewhere with the terms: PPSL, DJK

Guys, I decided to try 2 Rythmik servo 12"ers per side in a push-pull open baffle setup. Will report back how this goes.
