tend to add more “warmth” to the bass and lower midrange, possibly at the sacri-
fice of bass “tightness” and midrange clarity. Turning the setting down from the
recommended setting will make the bass and lower midrange sound “leaner.”
Phase Adjustment
Adjusting the Phase can be a little tricky. If you're in doubt, just leave the Phase
at 0 (zero). The best way to adjust the Phase is to get a friend to help you out.
Play music that features a good combination of bass notes and deep male vocals
at different frequencies. Have one person sit in the normal listening position
while the other person slowly rotates the Phase control until it reaches the posi-
tion that produces the fullest bass sound across the bass spectrum.
Installing More Than One IWSub In Your Room,
Or One Each in Each of Two Rooms
Installing two IWSub References into the walls of your room, or one each in
each of two rooms, will allow you to achieve a mind-blowing amount of bass
from subwoofers that take up no floor space! The SubAmp 600 has two separate
high power amplifiers for just this purpose. It is designed to drive one or two
IWSub References with full performance and maximum power delivered to each
subwoofer.
1. Connect inputs to the sub as described in Hookup Methods One, Two
or Three.
2. Use Speaker Wire to connect the top set of Sub Out Jacks on the SubAmp
600 to the terminals on one IWSub Reference.
3. Use Speaker Wire to connect the bottom set of Sub Out Jacks on
the SubAmp 600 to the terminals on the other IWSub Reference.
