Specs on Mid-high

Can someone point me to a plan for the attached Mid High. They are very popular on jamaican sound systems. It seems like a setup to play 4-way full range. Any help is great.

You will have to juggle up a few different plans for that one box

Altec on the bottom (15'') looks like a 12'' midrange horn, but you could also use a 10''. Looks lie a 2'', could get away with a 1''

Not a lover of Piezos unless they have double chees.........sorry! unless they are crossed very high
