Fidelity mm Efficiency

All Janszen Electrostatic systems are
classified in the generally accepted
term low cficirmcy". T10 reason for
aw czhcicncy and the considerable
advantages of it are often times
misunderstood and wrought with
misconceptions.

There is only one reason for making
(my speaker system (electrostatic or
dynamic) lou: efficiency: enhanced low
frequency reTonse. This is true in

all Janxzen E ectrm'tafic systems, since
the sensitivity (7] the electrwiutiv
arm can be set at whatever level

we r mire.

'ithout gmngintn a long and technical
dissertation. .mfiice it to say that in a
[Jinan . .alrincl, lmt; frequency
res-pom! is unrlisputably in direct
relation to efficiency. The higher the
clhnicntnj, if. the la. amplifier
power the woofer takes, the poorer
the low frequency response. F or
clarification. low frequency response
extends. by drfinitx'on, to the point
when the woofer in a given sized
enclosure achieves resonance and falls
oil rapidly thereafter.

We must admit that there is one
advantage to high efliciency systems,
rolumo. If loudness is a] more
importance to the listener than accurafl
hase response, then a high efficiency
dem'gn should be chosen. For inmmcc,
if a small amplifier is used, my 15
watts or less. and a lot of no umr is
desired. we would probably be forced
to recommend a high efiicienct
xyuem, since it would serve t it
function well. However, if optima lun's
response is desired and ' the am lificr
is at h as! 20 walla par c annel, the
listener has no other choice than to
choose a low efficiency system.
Additionally, if .wdhcienl am )lifim
paurrrr ix nnailahlr', the low . Clancy
.vysrcm mn, at least, equal the
loudness capability of most high
efficiency systems.

The hard. cold factx are that the direct
sacrifice for rfiicicncy ix low frequency
response, PERIOD. This is a
cmnpmmise that we at launch are
unwilling to make. Unfartunatelt ,
acme listeners are initially more
impremd with certain high cfiicienoy
systems because of their brute force
sensatimlalism. However. we, feel the
serious lixtent'r will see thrmlah this
misuse of acoustic? and ultimately
choose one of ours or one of several
other good low efficiency systems.
