Crossing over with main loudspeakers
Adjustment and tuning
The Sopranino is designed for reproducing very high
frequency information of music. The Sopranino is equipped
with a carefully designed filter to keep out the unwanted low
frequency signals from entering the units.
The crossover switch is preset to the following crossover
frequency
Matching the main loudspeakers
The Sopranino is designed with a nominal sensitivity at
86dB/1m/1W. It is a little bit lower than big floor standing
system and comparable to most bookshelf. After extensive
system verification and considering characteristics of
electrostatic tweeter, we recommended matching your main
system by the concept of spectral energy instead of sensitivity.
If a system demands more high frequency energy, you may
lower the crossover frequency (wider signal bandwidth into
Sopranino). If a system is overloaded with high frequency
energy, it is advised to raise the crossover frequency
(narrower signal bandwidth into Sopranino).
