There are three Concept Constanl
Energy speakers, expressions or the
same design philosophy The more ex-
pensive Concept models are designed ror
those who need higher Sound levels over
a wloer ireduency range and have the
space to aocorrrodale their ample dimene
slons; yet the three Concepts are far
more alike than dlflerent in technology
and sound.

of all, listen to It You'll find the least ex-
pensive Concept Wlll prove more exclting
than the best competing model.

In Search oi Design Excellence

As we pertecteo high-technology
electronics we became acutely aware ot
the imperlections inherent in exlstlng
loudspeakers. Our goal was to create
speakers whose perrorrnance would
equal that of the finest amplifiers, To
achieve our deslgn goal we llrst exam
ined all speaker technology existing or In
development. lt became clear that the
most serious llaws were in the reproduc-
tion ol crltlcal mid and high lrequencies
Even some speakers that tested flat failed
to create a convincing lllusion or either

needed a new tecnnology
