SAGE L75m 

 

WISDOMAUDIO.COM 

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.  

All 

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.
