THIEL speakers are completely designed and built in-house. Drivers, cabinets, and crossover networks are engineered with the highest quality materials and workmanship to deliver exceptional sonic performance, offer outstanding reliability, and produce beautiful cabinetry.

The 1-inch metal dome tweeter uses a large magnet, vented pole, reinforced rear chamber to allow low resonance frequency and a wide bandwidth. The result is high frequency reproduction of great clarity and realism.


The 6.5 inch woofer employs a very rigid aluminum diaphragm to eliminate cone break up and unwanted energy storage. A special short coil/long gap magnet system is used for extremely low distortion and improved mid-frequency performance, critical in a two-way system. A copper pole sleeve maintains a stable magnetic field and the driver employs two magnets with a total weight of 2.4 pounds. In conjunction with the bass radiator, which eliminates bass port resonances and noise, the CS1.5's woofer produces uncommonly clean and musical bass.
