The settings in the BSW150 have been set to default levels in order to work well with your Bluesound Player in
most listening environments. However, you may still require some adjustments to the settings based on placement
and personal preference.
The following procedure assumes your BSW150 is installed, connected to the network, and paired with a Player. If
you are using the BSW150 as a non-networked, powered subwoofer, your ability to do next-level calibration will be
limited.
With the Subwoofer audio settings menu open in the BluOS App, use these steps to fine-tune your subwoofer setup.
1. Set BSW150 volume to the lowest possible level. Set the crossover frequency to the lowest level,
meaning the crossover slider is set all the way to the left side. Set any special audio features, bass and
treble, or EQ controls on your paired Player to their nominal (midpoint or off) positions.
2. Play a familiar music source that includes substantial deep-bass content over an extended section.
3. Gradually turn up the volume of the BSW150 until you achieve natural balance between the
subwoofer’s deep-bass output and your speaker(s).
4. Gradually adjust the crossover up to reach the best mid-bass blend with your speaker(s). This will be
the point at which the upper bass retains solid impact and fullness. Boom or muddiness is the result
if the crossover is too high. A thin, ‘reedy’ quality to the mid-bass such as deep male voices (FM
announcers; Darth Vader) is the result if the crossover is too low.
5. Toggle the Phase control between 0° and 180° several times, leaving it in the position that yields
the fullest low to mid-bass output. You will now likely want to repeat steps 3 and 4 to check your
subwoofer blend.
Cycling through steps 3 and 4 several times with slightly different settings of both the volume and crossover
controls will help you get the most musical performance from your BSW150. The best combination is one that
yields the most solid very-low bass sounds, without mid-bass boom or a gap in response between the BSW150 and
other speaker(s).
The crossover and volume controls are interactive. Raising the latter while lowering the former can have the effect
of extending deep-bass response somewhat, with a small sacrifice in overall loudness capability. In general, for
well-recorded acoustic music the lowest crossover setting that still yields a smooth transition between subwoofer
and the main speaker(s) is often the best choice, and will promote deeper low-bass extension.
Note: The BSW150 volume control is not intended as a bass boost or daily volume control. It is designed as a set-
and-forget adjustment, and not for day-to-day use.
