As in its big sister, the speaker’s 15 cm mid-range, textile dome treble unit and sculpted “organic baffle” combine to form an acoustic unit which we have named CD = Constant Directivity. This is responsible for the speaker’s superbly spacious sound and outstanding radiation characteristics. The impregnated textile dome tweeter retains its lively, airy qualities even when reproducing extreme dynamic peaks, without any tendency to sound hard or sharp.

Like all CTL loudspeakers the S 2100 CTL is fitted with a sophisticated double-sided three-way crossover unit (FSR). It is effortlessly capable of handling even the highest levels, and provides perfect control of the three frequency ranges. The speaker’s impressive imaging and dispersion characteristics over the full frequency range are a direct result of the design of the crossover. The S 2100 CTL is effortlessly capable of processing very high levels, and provides a quality of low bass previously considered impossible from a cabinet of this modest size. Nevertheless, its bass response is not quite a match for that of the S 2200 CTL. Like the latter, its refined, carefully developed design also makes it the perfect choice for reproducing the most delicate music with natural sensitivity.
