Tapco SW-10 ユーザーズマニュアル

reinforces the direct sound, putting less of 
a demand on the power amplifi er to reach 
higher sound pressure levels.

It is important that the corner has good 

structural strength, or the low-frequency 
energy can cause rattling and other 
distracting vibrations.

Experiment with the orientation of the 

subwoofer. The driver in the SW•10 faces out 
the front. It may be helpful to play steady-
state tones or pink noise while a partner 
moves the subwoofer (perhaps on a small 
wheeled cart), to make it easier to hear the 
differences in the sound as the changes in 
placement and orientation are made.

One trick that has been used successfully 

to fi nd the best location for a subwoofer 
is placing the subwoofer in your listening 
position. The principle of reciprocity says 
that you can fi nd the best location for the 
subwoofer by switching places between 
the listening position and the subwoofer 
position. It is important that the cabinet be 
raised off the ground and at the same level 
as your ears. If that’s not possible, at least 
put the subwoofer in the same location as 
your listening position to achieve a close 
approximation.

Play music with a good strong bass 

line and crawl on the fl oor on your hands 
and knees until you fi nd a spot where the 
bass sounds the best, with a smooth, tight 
response. Your ears need to be at the same 
height that the subwoofer’s driver will be 
when it is sitting on the fl oor. If you have 
access to a real-time analyzer (RTA), play 
pink noise over the system and use the RTA 
to fi nd a location that exhibits the fl atest 
bass response. Once you’ve found the 
place where the bass sounds the best, put 
the subwoofer there and it should sound just 
as good from your listening position.

 The setting of the polarity switch can 

affect how the low frequencies sound in 
relation to the main speakers. Listen to bass-
heavy music with the polarity switch in and 
out. In one position the low frequencies 
should sound full, while in the other position 
they may sound hollow and thin. Choose 
the position that yields the fullest low-
frequency sound.

In many respects, every room is unique 

in terms of its acoustics. Even after you’ve 
placed your subwoofer where you think it 
will sound best, try moving it around. You 
might be pleasantly surprised.

•  Avoid using EQ to compensate for dips in the 

frequency response caused by room modes. It is 

better to place the subwoofer in a position where 

dips are minimized and use the EQ to smooth out 

any peaks.

•  Provide at least six inches clearance around the 

heatsink to allow air to get at it.

•  Never listen to loud music for prolonged periods. 

Please see the Safety Instructions on page 2 for 

information on hearing protection.

•   When you shut down your equipment, turn off 

the SW•10 active studio subwoofer fi rst (and 

any other powered speakers in the system) to 

prevent thumps and other noises generated by 

any upstream equipment from coming out the 

speakers. When powering up, turn on the powered 

speakers and subwoofer last.

•   Save the shipping boxes and packing materials! 

You may need them someday. Besides, your cat 

will love playing in them and jumping out at you 

unexpectedly. Remember to pretend like you are 

surprised!

•   Save your sales receipt in a safe place.

•   Also record the SW•10 serial number in the space 

provided on the inside front cover, along with 

where and when you bought it.
