Thiel cs1.6 Specification Guide

Page of 1
The new THIEL HigherPlane is an in-ceiling version of THIEL’s in-wall PowerPlane and the award-winning surface-
mount PowerPoint using the same high performance time and phase correct coaxial drivers and crossover design as
both to offer a much higher level of resolution and realism than found in conventional in-ceiling loudspeakers.
The HigherPlane’s 11-inch diameter, paintable, aluminum baffle and grille disappear into the ceiling, leaving only
the excellent sounds from your favorite music or movies. A special preconstruction mounting bracket is available to
simplify installation into new home construction.
High Performance In-Ceiling Coherent Source
• In-ceiling design allows for a wide variety of placement locations when space is a factor.
• Coaxial driver mounting insures accurate, natural sound regardless of speaker placement or listener location.
• Self-enclosed, rigid cabinet reduces unwanted vibration for greater clarity.
• 2-way driver system employs very low distortion, short coil, long gap motor systems, very rigid aluminum
diaphragms, and powerful magnets for superior reproduction.
• Phase coherent crossover networks preserve spatial and transient information for greater realism.

THIEL HigherPlane Specifications
THIEL HigherPlane Coaxial Array
The HigherPlane uses a coaxial/coplanar
6.5-inch woofer and 1-inch dome tweeter
that employ THIEL’s innovative short coil/
long gap motor system for extremely low
distortion. Designed and built in-house by
THIEL, the drivers use extremely rigid
aluminum diaphragms for outstanding tonal
response and the tweeter is the same unit
as used in THIEL’s flagship model, the CS7.2. Powerful, but small
neodymium magnets allow the driver array to be built small enough to fit the
compact enclosures, but still deliver outstanding performance. The powerful
magnet system improves the speaker output capability and increases
efficiency, important characteristics for use in today’s home theater systems.
