Beschreibung Description
Die C 12.2 ist eine kompakte, trapezförmige 12“ / 2-Weg Fullrange Box mit einer sehr
hohen Belastbarkeit von 500 W Continuous / 2000 W Peak und einem Wirkungsgrad von
97 dB 1W / 1m. Im Tieftonbereich kommt ein SMX 2120 Woofer zum Einsatz, im Hoch-
tonbereich arbeitet ein DH3 Compression-Treiber in ein 90° x 50° Constant Directivity
Horn für den Frequenzbereich oberhalb 1650 Hz. Flugpunkte für Eyebolts erlauben ver-
tikale oder horizontale Aufhängung. Zusätzlich ist optional ein Montagebügel (DC-
MBC12-UMH) erhältlich, der kompatibel zum DYNACORD PI-Easy Montagesystem ist
und eine Ausrichtung in bis zu drei Ebenen erlaubt. Zur Erweiterung der Tiefbass-Perfor-
mance wird ein parallel geschalteter Sub 1.15 Subwoofer empfohlen. Diese Kombination
ist auch ideal für ein Aktiv-2-Weg System zusammen mit den Controllern DSP 260 oder
DSP 600 und Endstufen der SL-Serie geeignet.
The C 12.2 is a compact, trapezoidal 12” / two-way full-range cabinet offering very high
power handling (500 W continuous / 2000 W peak) and sensitivity of 97 dB 1W / 1m.
The low frequencies are transduced by an SMX 2120 woofer, whilst in the high frequency
range, a DH3 compression driver in a 90° x 50° constant directivity horn handles every-
thing above 1650 Hz. Flying points for eyebolts allow the cabinets to be flown vertically
or horizontally. Available as an option is the DC-MBC12-UMH mounting bracket, which is
compatible with the DYNACORD PI-Easy mounting system and supports up to three levels
of orientation. To extend the low bass performance, a Sub 1.15 subwoofer connected in
parallel is recommended. This combination is also ideal for an active two-way system
together with the DSP 260 or DSP 600 controllers and power amplifiers from the SL
series.
