or audible strain. In fact, for a given size, they can handle many times the power
of a traditional dynamic driver.
Easy on amplifiers
Because the conductor is essentially a long, thin wire, it presents a purely resis-
tive load to the amplifier. This is comparable to the simple test loads that ampli-
fier companies use when measuring their amplifiers to show how terrific they
are. As such, you can be assured that your amplifiers will sound and work their
best.

magnetic drivers in particular, please refer to the Planar Magnetic Technology

Dynamic woofers
Authoritative, deep bass requires that you move a lot of air. We have chosen
to use dynamic woofers for the bass because they still provide the best perfor-
mance at low frequencies as compared to any alternative technology.
In order to get comparable 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.
Big bass in small boxes?
There is an old truism in loudspeaker design that goes something like this: “deep
bass, small enclosure, or high sensitivity — pick two out of the three.” No one
can cheat the laws of physics. If you want deep bass from a small box, you will
need to make up for the small size with equalization and extra power.
Fortunately, our system design comes to the rescue.
The system design includes both the SC-1 System Controller (which serves as an
active crossover, a system-specific equalizer, and a room correction system) and
the matching SA-series amplifiers. By dedicating high power amplifiers we can
give people what they want: great bass without huge, ugly boxes that are dif-
ficult to place.
Extraordinary drivers
Of course, the woofers themselves must be rather extraordinary in order to both
handle the power we deliver to them, and to “keep up” with the planar mag-
netic drivers right up to the crossover frequency.
Our woofers are different because they must be in order to do their job. Specifi-
cally, we need highly dynamic, uncompressed bass (to keep up with the planar
magnetic drivers) from an unusually small enclosure (so it will fit in the wall, or
on the wall, or in a tall, slim freestanding speaker). These two design goals re-
quire rather extraordinary attention to myriad details.
The magnetic structures employed in the Sage Series woofers are significantly
stronger than is commonly available — more than twice as powerful as typical
woofers, in fact. In addition, our voice coils are larger and capable of handling
more power than would be expected for a driver of similar size. Even the sur-
rounds that attach the diaphragm to the woofer’s basket (the metal frame) have
