POSITIONING THE SPEAKERS

Because of their unipolar radiation pattern, the CS3.7s will provide good results when placed in a variety of room locations. However, speaker placement will affect the accuracy of timbre, spatial performance, and bass perfor- mance. Here are some guidelines to help you achieve the best sound from your speakers. (The pointed metal stabilizer pins should not be installed until the final positioning has been determined.)

All aspects of speaker placement are dependent on the particulars of the room. Since every room is different, no hard rules can be given, and experimentation is necessary to achieve the best results.

Distance from walls

The CS3.7s, like most speakers, sound best if they are placed well away from all walls.

Such placement optimizes imaging charac- teristics, and musical timbres are repro-

duced with the least coloration because the

initial sound coming from the speaker is distinctly separated in time from the

secondary sound of wall reflections. If reflections are heard too soon after the primary sound, the brain tends to interpret

them as part of the initial sound, causing the perceived timbre to be altered and the

spatial characteristics to be confused. Figure 1 illustrates the problems caused

by early side wall reflections. When the speaker is placed too close to side walls, the difference in arrival times between the

primary sound waves and the reflected sound waves is too short for the brain to discrimi-

nate between them.

Figure 2 illustrates the advantages of placing the loudspeakers farther from side

walls. The arrival times of the primary, forward radiating sound waves and the

secondary, reflected sound waves are well separated, providing the proper delay needed for faithful tonal and spatial reproduction.

There will also be a noticeable improve- ment in openness when the speakers are even

two feet from the rear wall instead of one. If possible, we prefer the speakers three feet or more from the rear wall and five feet or more

from the side walls. Also, it is not desirable for large objects to be placed very near the speakers since these will also be a source of unwanted early reflections that reduce imaging accuracy.

CS3.7 specifications

Thiel Audio Products has long been synonymous with high-fidelity audio reproduction, and the CS3.7 loudspeakers stand as one of their crowning achievements. These speakers boast a unique combination of advanced technology and meticulous craftsmanship designed to offer listeners an unparalleled audio experience.

One of the defining features of the CS3.7 is its innovative coaxial driver design, which consists of a 10-inch woofer and a 1-inch tweeter. This arrangement allows for excellent time alignment, ensuring that sound waves reach the listener's ears simultaneously, creating a more coherent and lifelike soundstage. The integration of both drivers into a single source reduces phase distortion and enhances imaging, making it possible for listeners to perceive details and nuances in the music that might be missed with traditional designs.

The cabinet of the CS3.7 is constructed from high-density fiberboard, which minimizes unwanted resonance and vibration, further enhancing sound clarity. Thiel employs a unique trapezoidal shape for the cabinet, which helps to reduce standing waves and acoustical coloration. The interior is carefully braced to provide structural integrity, thus allowing the speaker to perform optimally even at high volumes.

The CS3.7 speakers feature Thiel's renowned second-order crossover design, which ensures a smooth transition between the low and high frequencies. This technology results in a natural roll-off and a balanced sound signature across the frequency spectrum. Additionally, the speakers are capable of delivering a wide frequency response, making them suitable for a variety of music genres, from orchestral compositions to intricate jazz solos.

Another notable characteristic of the CS3.7 is its impressive sensitivity, making it easy to drive with a wide range of amplifiers. This flexibility is advantageous for audiophiles who prefer different types of amplification, whether it be tube-based or solid-state systems.

The aesthetic design of the CS3.7 does not compromise on elegance. With a sleek profile and various standard wood finishes, these speakers can seamlessly blend into any home décor while serving as eye-catching statement pieces.

Overall, Thiel Audio Products CS3.7 loudspeakers represent a harmonious balance of innovative technology, refined craftsmanship, and acoustic artistry. Whether one's passion is listening to classical symphonies or exploring contemporary soundscapes, the CS3.7 offers an immersive audio experience that is sure to satisfy even the most discerning listeners.
