Application:
High
End
3 Way Speaker for Audio and Hometheatre speaker systems
Designers Notes:
The STONES
Fountek Ribbon crossover schematic
below can used as a general starting point for most 8ohm nominal
3 way high
end ribbon speaker systems.
The Ribbon Crossover is
set around 93.5 db Spl average power level so changing the valve of R2 to lower
valves of 22 or 15 ohm with add further attenuation for level matching lower
sensitivity bass midrange speaker systems .To increase the ribbon level to
around 95 db Spl average power level remove R2 47ohm resistor.
The tweeter phase ( polarity) may have to be reversed in some systems so Its a matter of experiment with
polarity and component
values to achieve your own personal sound quality and signature .
I recommend the use of quality components for this or any
ribbon crossover design . The sound quality and sound signature of the
components all interact with each other and the crossover electronic
design to ultimately determine the end sound quality
,distortion ,dynamic range and low level detail.
I also recommend the following brands and type of component to be
used in the tweeter crossover.
WES NL non inductive resistors , SCR MKP 400V capacitors ,Solen Air Core
or XLA Inductor ,QED Xtube 350 for Tweeter wiring QED Xtube 400 for Bass
Mid wiring, Eichmann Copper Speaker Terminals
