The THIEL CS3.7
The cabinet top is made of die cast aluminum into a shape that provides
dramatically improved vibration reduction, the practical elimination of
diffracted driver energy and the reduction of internal standing waves. Less
vibration contributes to greater clarity, while the absence of diffraction allows
for very open, boxless reproduction.
The tweeter is coincidently mounted with the midrange so the two drivers
are perfectly time coherent for every listener position and so every trace of
lobing is vanquished. This driver mounting system ensures that you will always
hear the sound with perfect timing and synchrony, creating a sense of realism
unachievable by any other means.
The midrange driver incorporates a radically new diaphragm geometry that
provides incredible rigidity and achieves perfect pistonic motion to the limits
of audibility. The diaphragm's flat shape also eliminates any altering diffraction
of the tweeter's output.
The cabinet sides achieve great stiffness by a construction of 15 hardwood
plies formed together into a curved, thick panel. This construction preserves
the nuances and delicacy of the music by reducing unwanted sonic artifacts
that would obscure musical detail.
The cabinet front is sloped to provide time coherence between the woofer
and the mid/tweeter array, preserving music's timing information. Because all
the discrete harmonics that make up the musical sounds are heard in perfect
synchrony, all the music's spatial cues are reproduced naturally.
The 3.7's front baffle is machined from aluminum to provide great rigidity
against unwanted vibration and to provide a very hard and rigid mounting for
the drivers, practically eliminating recoil motions of the drivers. Such a rigid
mounting system retains delicate information lost in most speakers.
The woofer's diaphragm contributes to extended bandwidth and high
while its very large magnet powers the copper stabilized, long gap motor
that achieves distortion levels only one-tenth the usual. The result is tonal,
effortless, and solid low frequencies.
The sophisticated crossover network provides complete phase coherence of
the musical harmonics so that the music's waveforms are preserved, while also
providing uniform energy response and exceptionally neutral tonal response.
The result is astonishing clarity, transparency, and true three-dimensional
realism you may not have known was possible.
