SubwooferPlacement
There is no argument among audio
professionalsthattheloudestbassoutput
from a subwoofer comes from corner
placement. The sound flaring outward
from a room corner focuses low
frequencies giving them no place to go
but toward you. In the case of
subwoofers,thereisnoautomaticpenalty
in giving overall balance for this peak
bass, since your main speakers can be
located elsewhere. It still may be too
much bass for your room or (more
particularly) your favorite listening spot in
the room, but unless you are seated in a
“void” spot, where sound from the sub is
cancelled or diminished by out-of-phase
reflections from elsewhere, there should
beplentyofbassfromcornerplacement.
If you are seated in such a void spot, your
only real choices are to move either the
subwoofer or your listening position until
the bass returns to the point that satisfies
yourlisteningcriteria.Turningup the level
control or changing the crossover point
almost certainly won't help much. But
flipping the phase control 180 degrees
sometimes may make a difference,
especially if the void is a product of
cancellations caused by interaction with
lowfrequenciesfromyour
mainspeakers.
UsingTwoSubwoofers
If you choose the use two woofers, the
sound output will double (an increase of
5dB).Locatethewooferswithoneineach
corner and experiment with the location
and phase control to achieve the best
bassresponse.
Always drive each woofer through the
Left/Mono input even though you are
driving one woofer on a right channel
drive and the other with a left channel
drive. If your pre-amplifier has a single
Sub/LFE output, use a 'Y' cable to split it
intotwooutputs.

Connecting Your Subwoofer

1.LocatetheLINEINRCAontheFF6.5amplifier.
2. Connect the FF6.5 to the signal source, i.e.AV receiver. Even though there is no need to have both
RCAs to the signal source since the subwoofer is often operated in mono signal, we recommend
connectingthereceivertobothRCAinputsinordertoobtainhighersignallevel.
3.If needed, connect the LINE OUTRCAto another amplifier to drive satellite speakers (front or rear).
