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.

 Tweeter/Midrange Coaxial Array
The CS2.3's most innovative design feature is a newly developed coaxial tweeter/midrange driver where the two drivers' diaphragms share the same voice coil. This technique allows the elimination of the midrange/tweeter section of the electrical crossover network as the drivers' structure provides a mechanical crossover. The coaxial mounting results in perfect time coherence regardless of listener position, greatly improving imaging and transient fidelity. The CS2.3 uses a 1-inch aluminum dome tweeter and a 3.5-inch aluminum diaphragm midrange. A very low distortion short coil/long gap motor system greatly increases openness and clarity.

Woofer
The 8-inch, long excursion woofer uses an aluminum diaphragm for broad, resonance-free operation, and a very low distortion short coil/long gap, copper-stabilized motor system for greater clarity. In combination with the 9-inch bass radiator, which eliminates bass port resonances and noise, the CS2.3 delivers high bass output and dynamics down to 35Hz.Very rigid cast aluminum chassis also improve clarity.

 Crossover Network
THIEL's first-order electrical networks insure complete phase accuracy for natural, three-dimensional imaging. Some of the network's circuitry is also used to correct frequency response irregularities improving the speaker's overall frequency response. Very high quality components such as polystyrene and polypropylene capacitors, and air core inductors wound with high purity, low oxygen copper are used for low distortion and transparent reproduction. The networks are hand assembled with silver solder connections and individually tested before installation.
