Thiel CS1.6 loudspeakers

Coherent Source ® Loudspeaker

 

The CS1.6 is a 2-way floor-standing model incorporating several new innovative design techniques that greatly improve performance in a small, floorstanding loudspeaker. The 36-inch tall CS1.6 delivers a much purer and more open upper midrange response coupled with a sweeter and smoother high frequency performance than conventional two-way models. The new CS1.6 also offers a very high 90 dB efficiency to work well with lower amounts of amplifier power.

Completely Time and Phase Coherent

As with all THIEL loudspeakers, the CS1.6 is completely time and phase coherent for much greater sonic realism. THIEL’s Coherent Source® technology achieves the elimination of both time and phase distortions that cause alterations in the reproduced musical waveforms of most loudspeakers. Eliminating these distortions results in enhanced realism, clarity, transparency and immediacy as well as improved imaging and soundstaging in both the lateral and depth perspectives. Phase coherence is achieved by utilizing a sophisticated first-order electrical crossover system in conjunction with unusually wide bandwidth drivers. Time coherence is achieved by placement of the drivers on a baffle that is sloped at the correct angle to cause the sound energy from each to reach the listener at the same time.

 

Innovative Woofer and Tweeter Design

Much of the CS1.6’s outstanding performance is the result of its new high output, high efficiency aluminum dome, 1-inch tweeter and the innovative woofer diaphragm/voice coil design. Both drivers incorporate short coil/long gap, copper stabilized motor systems to greatly reduce distortion, employ metal diaphragms for very uniform Frequency response and clarity, and use Long Excursion Motor Systems for high Output capability.

 

High performance from a small, floor-standing loudspeaker

The CS1.6 is a two-way, floor-standing speaker system that incorporates THIEL’s latest innovative driver technology, rugged cabinet construction, and phase/time correct Coherent Source® design. Allmetal diaphragm, low-distortion drivers are used for outstanding tonal response and the advanced phase correct crossover design greatly improves spatial fidelity and clarity.

 

High output, high efficiency tweeter

The CS1.6 tweeter is a high output, high efficiency aluminum dome unit with long excursion abilities that reduce distortion and increase output capability. The new high frequency driver uses a short coil/long gap motor system design for low distortion, a copper sleeve to stabilize the strength of the magnetic field for reduced distortion, and practically unbreakable lead wires for increased reliability—features all shared with THIEL’s more expensive models’ tweeters.

 

Metal diaphragm, low distortion woofer

The CS1.6’s 6.5-inch woofer uses a much larger than normal diameter voice coil to greatly extend the woofer’s bandwidth for improved upper midrange performance. The large diameter coil distributes its driving force over a large area of the cone rather than concentrating it at the center. This coil design coupled with the woofer’s metal diaphragm increases the cone’s stiffness and frequency of unwanted resonances for very clear and open reproduction. The short coil/long gap, copper-stabilized motor system dramatically reduces distortion. Equally innovative is the woofer’s centrally located neodymium magnet that is placed inside the coil, rather than outside, creating an inherently shielded speaker to prevent picture distortion when placed near video displays.

 

Cabinet construction

The compact cabinet is built with a 2-inch thick front baffle and 1-inch thick cabinet walls for extreme rigidity to reduce unwanted vibration, improving clarity and spatial performance. The baffle’s rounded edges reduce diffraction effects for improved tonal, spatial, and transient performance, and its sloped front correctly time aligns the tweeter with the woofer. The unique slotted bass reflex system reduces unwanted port noise and grille loading effects.

 

Finished in the world’s finest woods

The CS1.6 is available in a wide variety of exquisite, real-wood, laminate, and painted cabinet finishes, finely crafted to enhance any home environment.
