Your P2i and Subwoofers
Using with subs All Insight Series loudspeakers are optimized for use with subwoofers, with a
crossover of 80 Hz. (This is the most common frequency below which subwoof-
ers are used.)
When properly installed in the wall, your P2i has inherently at response to 80
Hz, without the common “bass bump” that characterizes most in-wall speakers
and is placed there to yield the impression of “more bass” than there really is.
This makes it easy to blend seamlessly with a high quality subwoofer such as
one of Wisdom Audio’s Regenerative Transmission Line™ (RTL™) subwoofers.
You should set up your surround processor for a crossover of 80 Hz and dene
all your Insight speakers as “Small” in the speaker setup portion of your proces-
sor’s menu system. Doing so ensures that all content below 80 Hz is directed to
the subwoofer(s) for reproduction.
Using full range In some installations, the Insight Series speakers may be used full-range rather
than with a subwoofer. If so, we recommend using a two-pronged approach to
get the lowest distortion and best performance from your Insight Series speakers.
1. Purchase and install 70 Hz in-line lters such as the ones found
here, at Parts Express:

272
2. Optionally, if your system has some basic EQ capabilities, boost
the range around 60 Hz by perhaps 3 dB
The combination of these two lters will yield full-sounding natural bass, while
attenuating the lowest frequencies that normally would be reserved for a sub-
woofer.
