CS 3.7

About the CS 3.7

The Thiel Audio CS-3.7 is a three-way, floor-standing loudspeaker designed with advanced driver technology and a phase/time coherent Coherent Source design. It features a unique coaxial midrange and tweeter driver with a 1" aluminum dome tweeter mounted coincidentally within a 4.5" flat aluminum midrange driver, a 10" flat aluminum woofer, and a 10" flat aluminum passive radiator. The speaker uses first-order acoustic crossovers to minimize phase shift and time misalignment, resulting in exceptional frequency, phase, and time response. The cabinet is constructed with multiple layers of hardwood and an aluminum top to reduce vibrations, with a sloping front baffle machined from aluminum for driver stability. It delivers a frequency response of 33 Hz to 26 kHz ±2 dB, sensitivity of 90 dB at 2.8 V/1m, and nominal impedance of 4 ohms (minimum 2.8 ohms). Recommended amplifier power is 100 to 600 watts. The CS-3.7 weighs 91 pounds and measures approximately 45" high by 12.5" wide by 21" deep. It is praised for its extremely accurate tonal response, high resolution of detail, realistic imaging, and dynamic contrast preservation. The speaker is suitable for a wide range of music genres and offers a practical yet high-performance solution without requiring exotic amplification or bi-wiring. It comes with a 10-year parts and labor warranty and is available in various wood finishes including Amberwood, Walnut, Black Ash, Cherry, Oak, and Maple. The
