1.2 The Subwoofer CDR 210 C
Design and Construction of the Subwoofer
Made of 19 mm, 13-ply birch plywood, the CDR 210
C enclosure is coated with water-repellent, black
acrylic enamel. The baffle board cover consists of a
metal grille.
The CDR 210 C weighs 48 kg. It is 55 cm wide, 60
high and 63 cm deep. Two slot grips have been
routed into the top, bottom and back panels for easy
transport and set-up.
Electrical and Acoustical Data
The CDR 210 Sub enclosure is loaded with two 10"
woofers. The loudspeakers are treated with a special
coating protecting them against dirt and moisture.
The CDR 210 C enclosure’s nominal electrical
power-handling capacity is 600 watts RMS at 8
ohms impedance. It produces a sound pressure level
of 104 dB (1W@1m), measured under half-space
conditions. Maximum SPL measured under the same
conditions at a distance of one meter is 139 dB at
10% THD**. The frequency response of the CDR 210
C ranges from 47Hz to fx (± dB).
Connections
The connector panel on the rear of the CDR 210
C enclosure is recessed to protect the ports from
harm. On this enclosure, you’ll find two Speakon
®
NL 4 connectors. Both ports’ four pins are wired in
parallel. Pin assignments are pin 1+ = mid/high +,
1- = mid/high -, 2+ = sub +, 2- = sub -.
