Authoritative, deep bass requires that you move a lot of air. We have chosen to use
dynamic woofers for the bass because they can provide excellent performance at lower
frequencies.
To get comparable bass performance from a planar magnetic design, you would need to
have a huge speaker that would be impractical in most domestic living spaces. It simply
makes more sense to use the best transducer technology in each 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.
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.

Sage Series
speakers have been designed to optimally crossover at
80 Hz, which is the most-common crossover frequency used with subwoofers.
Line Source Speakers
Almost all loudspeakers radiate sound into the room as imperfect “point sources”. This
means that most of the energy they put into the room expands as an ever-enlarging
sphere, as though emerging from a single point in space. This results in a multitude of
reflections from the ceiling and floor that can degrade sound quality.
