SUB 15 ACTIVE SUBWOOFER

Active Class H 15" Subwoofer

The SUB 15 sets a new standard in ultra compact

active subwoofers.

The heart of the SUB15 is the new high power 15"-

woofer with 3" coil, designed and manufactured by

ddBB

Technologies, made to deliver peak performance to

this bandpass enclosure. Massive power reserves are

guaranteed with the new processor controlled Class H

amplifier, delivering a solid 800 W/RMS. Operational

safety is assured with DC, Overheat, RFI protection

circuitry, as well as a full wave Peak Limiter. The

combination of our custom designed woofer with our

MT amplifier, achieves a maximum SPL of 133 dB at a

weight of only 32 kg / 70,5 lb. The integrated active

crossover, used in mono or stereo mode, gives max.

flexibility - the SUB 15 can be used both as a single subwoofer supplying low-cut signals

to 2 satellite speakers, or in mono mode with one subwoofer per side. The crossover

frequency is switchable from 80/100 to 120 Hz and provides a very narrow rollover of

24dB / octave. The phase can be turned by 180° if the position of the SUB15 is not in

line with the satellite speakers. As with all

ddBB

Technologies subwoofers, the amplifier

module is placed in a separate compartment inside the enclosure, to avoid “air noises”

from the woofer through the cooling slots. The 4-speed temperature controlled fan

assures safe operation even under hardest driving conditions. The fan is covered with a

removable dust filter. Four control LED’s mirror the operating status of the system, to

ease set-up, and safe operation. The SUB15 can be used in combination with all OPERA

Live speakers, or as a high performance low extension for existing systems.
