I am planning on building a finger jointed pine cabinet and then giving it a tweed covering for my 1987 green board Blues Junior amp. As well as the original 12" Eminence 8ohm speaker I have an 8" Eminence 4ohm 820H Patriot I had bought for an other amp I had. I originally intended to build a head and a speaker cab but think I would prefer to stick with it as a combo. To this end I will buy another Patriot 820H. Now my idea here is to build the speakers in a triangle with the 12" on top and the two 8" underneath and run separate jacks from the 12" and the two 8" speakers wired in series which would give me two options both at 8ohms. Now I will be happy enough with that if that is how it turns out but would it be possible to wire all three speakers together in parallel and retain the 8ohms. 8+4+4=16 giving 8ohms wired in parallel, I have a feeling I am wrong but thought I would ask anyway?.
