area of the reproduced spectrum. One of Wisdom Audio’s strengths is in seamlessly
blending these technologies — particularly important given the high standards set
by our planar magnetic drivers.
Of course, the dynamic woofers themselves must be rather extraordinary to “keep
up” with the planar magnetic drivers right up to the crossover frequency.
Our woofers are different because they must be to do their job. Specifically, we
need highly dynamic, uncompressed bass (to keep up with the planar magnetic
drivers) that does not depend on a critical amount of enclosure volume (since these
speakers are mounted in your wall and use the space inside the wall as their
“enclosure”). These two design goals require rather extraordinary attention to
myriad details.
The motor and suspension system of these woofers therefore includes all the critical
damping required for optimal operation. (In most speakers, the woofers depend on
the air trapped inside their enclosures as an additional “spring” to help them
behave properly.) Technically, this approach is known as an “infinite baffle”
design. In practice, the volume of air behind the speaker does not have to be
infinite, of course. It just needs to be large enough to not act like an acoustic
“spring”. Recommended and minimum enclosure volumes for the speaker are
listed in the Specifications section and repeated on the Dimensions page.
Many speakers include a mid-bass “bump” in their response to give the illusion of
going deeper in the bass than they actually do. Unfortunately, this “bump” makes
blending them seamlessly with a high-quality subwoofer almost impossible.
All Insight Series speakers have been designed to optimally crossover at 80 Hz
which is the most common bass management transition used to integrate with
subwoofer(s).
Unpacking and Installing the P4m
Your new Wisdom Audio Insight Series P4m in-wall speaker is relative compact,
but surprisingly massive compared to most in-wall speakers. Please exercise
caution when unpacking your P4m to ensure that you do not strain yourself from its
(perhaps unexpected) weight.
