INFINITE BAFFLE EXAMPLE HIGH-PASS SET @ 30Hz
By removing low frequency signal
which the woofer cannot produce, the
woofer can play its capable range
louder The first example is an infinite
baffle situation. The left Graph
displays the frequency response of
a 12 inch woofer in an infinite baffle
application without the high-pass filter,
with the filter and with the filter and the INTELLi Q set to +3dB. As you can see with +3dB of boost and the high-pass filter set to
30Hz, the woofer has more output down to 25Hz and less overall excursion when compared to the non-high-pass response. Maxi-
mum physical excursion capability of the woofer is 15mm.
SEALED EXAMPLE HIGH-PASS SET @ 20Hz
This sealed example is the same 12 inch
woofer in the recommended sealed
enclosure. Up to 6 dB of boost is
capable at 20 Hz was used. With +6dB
of boost, the woofer has more output
down to 15 Hz.
