"Recommended Component" 2002 - Stereophile Guide to Home Theater
Breakthrough Loudspeaker Design
The MCS1 is a breakthrough loudspeaker for achieving high performance sound from an easy-to-place cabinet in home music and video sound systems. The MCS1's extremely realistic reproduction, combined with high output capability, high efficiency, and magnetic shielding makes it a truly ultimate performance multi-channel loudspeaker.
Ideally suited for main, center, and rear channel use, the MCS1 is designed to provide maximum performance with vertical, horizontal, shelf, or stand placement. It provides great realism for both music and movies, and the beautiful cabinetry integrates well into any room.
The MCS1 is such a great performer, it won the much sought-after "Recommended Component" status in 2002 in Stereophile Guide to Home Theater magazine.
"The Thiel MCS1 array has so many qualities that make it an ideal choice for a do-it-all, flexible system that I hardly know where to begin," notes Jeff Fritz in his June 2001 review for Home Theater Sound / Soundstage! "The MCS1 system is a real winner."
Tweeter / Midrange Coaxial Array
One of the MCS1's most innovative design features is a newly developed coaxial tweeter / midrange driver where the two drivers' diaphragms share the same voice coil. This technique allows the elimination of the midrange/tweeter section of the electrical crossover network as the drivers' structure provides a mechanical crossover. The coaxial mounting results in perfect time coherence regardless of listener position, greatly improving imaging and transient fidelity.
The MCS1 uses a 1-inch aluminum dome tweeter and a 3.5-inch aluminum diaphragm midrange. A very low distortion short coil / long gap motor system greatly increases openness and clarity.
Dual 6.5" Woofers
The two MCS1 6.5" woofers use metal diaphragms to eliminate resonances in the operating range for very clear and open reproduction. Expensive short coil/long gap, copper stabilized motor systems dramatically reduce distortion. The 2.2 pound magnet increases output capability and efficiency.
Aluminum Domes and Cones
THIEL employs aluminum as a diaphragm material in all of its tweeters and most of the cone drivers. Aluminum has much higher stiffness and compressive strength than conventional diaphragm materials, and therefore provides a broader range of resonance-free operation. The result is extremely clean and open reproduction with no ringing.
An additional benefit is that the aluminum's greater compressive strength causes virtually all the energy of a transient attack to be transferred to sonic output instead of being absorbed by the diaphragm itself.
Phase Correct Electrical Crossover
The phase correct electrical crossover design improves spatial and transient performance. The network also corrects small tonal irregularities, improving frequency response. Pure polystyrene and polypropylene capacitors, and air-core inductors wound with high purity copper wire preserves sonic information for even greater fidelity.
Why Phase Coherence?
Loudspeaker crossover networks are needed to direct the incoming signal to the appropriate driver - woofer, midrange, or tweeter. To preserve the critical phase relationships of the sound recording's harmonics, all the drivers' diaphragms must move in and out in step with each other and the speaker's input signal. THIEL's phase-correct electrical crossover networks represent state-of-the-art engineering that greatly contributes to the exceptional sound reproduction provided by THIEL's entire line of award-winning loudspeakers. |
