Hi,

Does anyone have Supertower/R or Tower ii schematics?  Looking for schematics from 1985 to 1990 vintage.  I have my Supertower/R schematic from my kit but want to compare it to others.  I think I may have a midrange wiring problem.  I don't have schematic for my Tower ii. 



Thanks,

Ed

Thank you for posting.  The first thing that strikes me is the capacitor value for the mids in the drawing is 4.19uF.  Mine is around 50uF, over an order of magnitude different.  Wouldn't that change the crossover frequency by a decade?  What mids are you using?  Any other Supertower/R owners know the value of this cap in their cabinets?  I wonder if this is part of my problem.

my mids are carbon fiber cone speakers, not the Dynaribbons.

My speakers are diff from most Towers I've seen:

Well, that could explain some of it.  Your mids are different.  Where is the crossover point to your mids?  Mine originally was at 600 Hz, then changed to 450 Hz.  My mids look like this:

except they are four ohms instead of eight.  Brian called them the "classic mids" when I ordered them from him but I don't know where he got them.  The resemblance could be coincidental.
