The DBA10 is a passive subwoofer that requires external amplification. While
any amplifier with enough power (100-200 watts) will be suicient to drive the
subwoofer, there are other considerations you will need to address. The DBA10
is designed to reproduce frequencies below 150Hz. Therefore, running full
frequencies to the sub will result in less than optimal performance. If you are using
an Audio Video Receiver (AVR) that has Dolby/DTS processing, there will be a line
level, subwoofer output. This output will typically have adjustments to determine
the low frequency crossover point, eliminating the higher frequencies, and a level
adjustment. This output CANNOT be plugged directly into the DBA10 as it is at
line level and must first be connected to an amplifier that will boost the signal
to speaker level and then connected to the subwoofer. For the highest quality
performance, Origin Acoustics has two amplifiers that are specifically designed
to drive the DBA10 as well as other in-wall and in-ceiling subwoofers in the Origin
line. The SUBA150 is a dedicated, single-channel subwoofer amplifier with both
line level and speaker level inputs. The crossover point, phase and volume level
can be adjusted from the front panel to blend the DBA10 with the satellite speakers
in the room. The DSP3-100 is a three-channel amplifier providing 100 watts of
power to a dedicated subwoofer channel as well as independent channels for
the le and right speakers as well. The versatility of this amplifier is found in the
powerful Digital Signal Processing (DSP) that allows for a myriad of adjustments
to fine tune the signal delivered to the subs and satellites. Follow the wiring and
set-up instructions included with amplifier you choose.
