1.3 The CDR 210 F Sub Subwoofer
Design and Construction of the Subwoofer
The CDR 210 F Sub's enclosure is made of 19 mm,
13-ply birch plywood and coated with water-repel-
lent, black acrylic enamel. The baffle board cover
consists of a metal grille.
The CDR 210 F Sub weighs 40 kg. It is 65.5 cm
wide, 48 cm high and 60 cm deep. Two slot grips
have been routed into the side panels for easy
transport and set-up.
Electrical and Acoustical Data
The CDR 210 F Sub enclosure features two
10" woofers. The enclosures are provided with
a special coating that protects them against dirt
and water.
The CDR 210 F Sub 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. Frequency response ranges from 47 Hz
to fx (± dB).
Connections
The connector panel on the rear of the CDR 210 F Sub
is recessed to protect the ports from harm. On these
enclosures, 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 2-.
