The STUDIO 90
TL is
our flagship, the audiophile high point of our loudspeaker program.
It
plays everything: Classical, live, jazz. music. In our demonstration
program Rock, Pop
House-Music are just as successfully reproduced. Fewer loudspeaker
designs can
as accurately reproduce the sound of kick drums. The legendary TDL
oval bass driver
performs completely "stress-free" into the deepest
registers: 20 Hz with ease.
can play at lower than 30 Hz and then only at loud levels. The
special AOS/ScanSpeak
18W16545K is an ingenious design and one of the best being built
today. The paper carbon
diaphragm is so large that it could be voiced more than one octave
lower. The diaphragm is
so unstressed that it could play problem free well into the range of
the tweeter. The small
ScanSpeak Revelator tweeter 2905/9700 with a rectangular front plate
is used. This is the driver
which Klang und Ton magazine chose as the best over all non-ferrous-fluid
tweeters tested. Why
the rectangular shape? Because we can then locate the tweeter about
8mm closer to the midbass driver.
