Using a Subwoofer
The Micro SE and A’Diva SE can be used without a subwoofer if you wish. However, your system
will obviously deliver much better bass with a subwoofer.
Also, the Micro SE and A’Diva SE will play louder when used with a subwoofer and a high-pass
filter (or crossover) in the system to prevent deep bass frequencies from reaching the speaker. The
high-pass filter can be in an A/V receiver or surround processor, or built into your subwoofer. We
prefer a direct connection from the amp to the subwoofer and then from the sub to the satellites.
Note that while all Anthony Gallo Acoustics subwoofers have a high-pass filter built in, most other
subwoofers do not. If you plan to use the high-pass filter built into your subwoofer, and the
subwoofer’s made by another company, check with the manufacturer of the subwoofer to make
sure it has a high-pass filter built in.
Subwoofer crossover point – receivers and surround processors: Start by setting your receiver or
processor for “small” speakers, with the subwoofer “on.” If your receiver or processor lets you
adjust the subwoofer crossover point, we recommend setting it somewhere between 80 and 120
Hz, depending on the options the receiver or processor offers. With the Micro SE, best results will
be achieved with a setting of 100 to 120 Hz. With the A’Diva SE, try 80 or 100 Hz.
Subwoofer crossover point – Anthony Gallo Acoustics subwoofers: The high-pass filters in Anthony
Gallo Acoustics subwoofers are preset to work well with the Micro SE and A’Diva SE. Set the
subwoofer’s crossover point (low-pass filter) to 100 to 120 Hz for the Micro SE, 80 to 100 Hz for
the A’Diva SE.
Subwoofer crossover point – other subwoofers: Very few subwoofers have an adjustable high-pass
filter. If yours does, set the high- and low-pass filters (sometimes adjustable separately, sometimes
controlled by the same knob or menu option) to 100 to 120 Hz for the Micro SE, 80 to 100 Hz for
the A’Diva SE.
If your subwoofer doesn’t have an adjustable high-pass filter, set the subwoofer’s crossover point
(low-pass filter) to 100 Hz for the Micro SE, 80 Hz for the A’Diva SE. If the bass sounds thin, raise
the crossover point to the next highest frequency.
TECH TIP: Choosing a higher subwoofer crossover point will let your satellite speakers
play louder without distortion, but you may hear voices coming from the subwoofer.
Choosing a lower crossover point helps prevent voices from coming out of the sub, but
you’ll get more distortion and you may hear a “hole” between where the sub’s response
drops off and the satellite’s response picks up. Let your ears by your guide.
