In spite of its modest height the S 2000 CTL also ranks as a fully developed transmission line floor-standing speaker with a very long transmission line; this is made possible by the substantial depth of the cabinet and the folded duct. The two 15 cm bass drivers have a very low resonant frequency, and are exactly matched to this line. Their extremely hard, embossed cones enable them to generate a very low, forceful and accurate bass. The 12 cm mid-range unit, the dome tweeter and the sculpted baffle form an acoustic unit which guarantees a constant radiation pattern in the transitional area between mid-range and treble (CD = Constant Directivity). Combined with the narrow baffle, this is responsible for the speaker’s superb radiation characteristics and astonishingly spacious sound.

Since the dome tweeter is positioned below the mid-range unit, the acoustic axis in the mid / treble range rises as the distance to the listener increases, thereby compensating for the speaker’s small height. This is helped by the carefully calculated design of the crossover unit. These features help to produce brilliant, natural-sounding reproduction of the entire mid / treble range significantly above the speaker itself. In spite of its small size the S 2000 CTL is effortlessly capable of processing high levels, and generates very good deep bass responce. It sounds free and natural, with astonishingly spacious sound and dynamic range.
