CS 2.7

About the CS 2.7

The Thiel Audio CS 2.7 is a three-way, time- and phase-coherent floorstanding loudspeaker using a first-order 6dB/octave crossover network and a passive radiator for extended bass response. It employs a coincident 1-inch aluminum dome tweeter and 4.5-inch aluminum cone midrange driver derived from the flagship CS 3.7 for precise time alignment and coherent wavefront reproduction, alongside an 8-inch aluminum cone woofer and a 9.5-inch passive radiator. The cabinet is crafted from curved premium-quality plywood with furniture-grade hardwood veneer, and the sloped front baffle ensures proper acoustic alignment. Nominal impedance is 4 ohms, sensitivity is 87dB, and recommended amplifier power is 100 to 400 watts. The CS 2.7 was produced from approximately 2012 until Thiel Audio closed in 2018, and is highly regarded for its musicality, clarity, and dynamic range. It is no longer manufactured.
