The CS6 sets a new standard in loudspeaker performance

The exceptional sonic performance of the CS6 is the result of an evolution in speaker design unlike any other in the audio industry. It is the culmination of years of painstaking development of a lineage of the world's most outstanding loudspeakers through innovative driver design, superior cabinet contruction, and accomplished crossover execution.

 THIEL designed and built in every way

The CS6 is a three-way system incorporating all THIEL-designed and built metal diaphram drivers - a 1-inch dome tweeter, 4-inch midrange driver, and a 10-inch woofer. As with all THIEL speakers, the CS6 utilizes a first-order crossover system to eliminate phase distortion, a sloping front baffle to provide accurate time coherence, and very high quality components to reduce distortion and improve clarity.

CS6 phase coherent crossover system

 


 

 The CS6 uses coaxially mounted tweeter and midrange drivers so that the critical upper frequencies remain perfectly time coherent, regardless of where you sit, improving imaging and transient fidelity. Performers and instruments seem to occupy real space in the room, and details in the recording soundtrack are heard much more clearly.

The tweeter employs a very long magnetic gap and large excursion rubber surround for very high output. The midrange driver uses a three-layer sandwich construction diaphragm of aluminum/polystyrene/aluminum specially shaped to act as a waveguide for the tweeter's energy. The shape reduces diffraction, which is a problem with conventional coaxial designs. The three layers increase the diaphragms rigidity, improving clarity and realism.


Cabinet construction and mineral polymer baffle
The movement of individual drivers can cause unwanted vibrations to be emitted from the cabinet, especially from the front baffle. The CS6 cabinet uses a very rigid cast mineral polymer baffle to greatly reduce energy storage and unwanted vibration for improved clarity and imaging performance. Internal cabinet bracing, 1-inch thick cabinet walls, and cast magnesium driver chassis further reduce unwanted vibration.

The midrange driver also has its own non-reflective sub enclosure to isolate the midrange from interaction with the woofer,and further reduce diffraction for better midrange performance.

 



Woofer
The 10-inch woofer uses a very heavy 20-pound magnet structure and a short coil/long gap motor system for exceptionally clean, deep bass response to 27 Hz a fraction of the distortion found in most other bass drivers. The rigid aluminum diaphragm provides resonance-free operation for uniform response and very open reproduction. A heavy copper ring maintains an ultra-stable magnetic field.
