The CS3.7’s input terminals are located on the lower rear of the speaker cabinet. The CS3.7 uses 5-way binding posts that accept several types of wire connections. Regardless of the type of wire termination, make sure that all connections are tight. The input terminals are designed to be easily tightened by hand or a 1⁄2 inch nut driver can be used.

It is essential for proper performance that both speakers in a stereo system be wired in the same polarity. The speaker’s input terminals are color coded to facilitate this. The wire connected to the red ringed input terminal of each speaker should connect

to the respective positive (+) output terminals of the amplifier; the wire connected to the black ringed input terminals should be connected to the respective negative (–) output terminals of the amplifier.

The speakers should be connected to the amplifier with high quality cable to ensure minimal loss of power and proper control by the amplifier. If the speakers are being connected to a vacuum tube amplifier with various impedance taps, the 4 ohm tap will usually give the best results.

STABILIZER FEET

The speakers should be positioned before the stabilizer feet are installed.

Speakers positioned on a soft or uneven surface are able to rock slightly and will vibrate in reaction to forces the speaker generates to move the driver diaphragms. (Every action has an equal and opposite reaction.) This motion slightly reduces the music’s clarity.

To eliminate this effect, the CS3.7s can be used with four stabilizer feet on uneven surfaces or on carpeted floors to provide a more solid footing and allow the speaker to couple more firmly to the floor. To install the feet:

•Position the speaker in the desired location.

•Tilt the speaker forward slightly so that the back of the speaker is a few inches off the floor.

•Screw one foot, with the locking nut threaded all the way onto the foot, into each of the

two holes at the back corners of the speaker bottom. The pins should be screwed into the speaker until there is about 1⁄4" of thread remaining visible.

•Let the back of the speaker down and then tilt the speaker backward slightly so that the front is a few inches off the floor and install the two front feet.

•With all four feet installed, the height of each foot should be adjusted so that the speaker stands firmly on the floor without wobbling. Then tighten the lock nuts by turning them so they are tight against the cabinet to secure the feet to the cabinet

Please be cautioned that the stabilizer feet can dent hardwood floors and it is possible to mar the floor’s surface if the speakers are moved with the feet in place.

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.
