Synchrony Port Cover
A Port Cover accessory is
supplied with each tower
(Synchrony One and Two) and
center channel speaker
(Synchrony One C and Two C).
The port covers can be used to
adjust the bass tuning of the
Synchrony models where room
problems at low frequencies (in
the 100Hz region) occur. It is well
known that the room can
dominate the performance of the
low frequencies below 200Hz and
the added flexibility of a port cover
can tweak/improve the
performance in problem room
setups. For example, by covering
the top port on the Synchrony
Two the output in the 75Hz to
125Hz region will be reduced by
2dB.
The use of the port cover is not
limited to only closing one of the
ports in the case of the towers
(Synchrony One and Two). We
invite the listener to try plugging
any one or multiple ports to better
integrate the system in their room
because any adjustment of the
bass balance could be a welcome
improvement in a given system
setup. Please experiment; it will
be worth the effort in many cases.
It's impossible to predict what type
of room or what the system setup
will be, therefore we think the flexibility of multiple chambers and ports
allows the speaker to be integrated better in a wider variety of situations.
Sometimes tweaking like this can be used to really help “dial in” the best
possible sound in your room.
Additional Port Covers can be acquired for a nominal fee in cases where
multiple ports need to be covered to achieve the proper bass balance in
a given setup. One can also experiment with the Port Cover on the
bookshelf models (Synchrony One B and Two B) to tame the bass in
some setups.
