Well...Stefan, we've been over this before! Choose Thiel & Partner units and stop messing about with these Scan Speak units! ;-D
Wilson Sophia is, i guess, not VERY easy to clone...Although, many like the sound they give, but to be frankly, I have as many friends that dislikes 'em as I have heard fantastic reviews...
Why not start something more 'new' by your self!?? Golden Age, in Alingsås Sweden, could help you out if you specify what kind of speaker you want! I guess you in your ProAv clone lack of deep bass, sensitivety and detail can always be better! There are a lot of interesting units out there... Mangers unit is very nice as well as good sounding! Match up with an Eton bass (the new 12 inch one...) and a fairly simple cross over...and your done!
Or may be T&P tweeter + T&P midrange (they are releasing a new and, hopefully, better 5 inch'er) and add a bas driver (T&P, Eton, TC Sounds etc etc...Why not Skaaning?
www.flexunits.com Have a look at thier mids and bass units! I guess they rock!
I guess Micke can sell the nye Vifa ring radiator tweeter! Match that one with some fancy mid and a bass unit!
Soooo many options...
Well...let me know what ever it will be!
