WHAT IS HOLOCRAPHIC
IMACINC?

It's the vivid recreation of the sonic
space on a recording and the exact
positioning of instruments and
singers within that space.

Think of these two pages as a
nzurative spec sheet-highlighting
some of the concepts which have
gone into developing this new
mode of stereo enjoyment.

ANCLINC THE WOOFER UPWARO.
This projects smooth. flat sound at
the critical crossover point directly
toward your ezu and ample hall
simulating rnidrange reverberation
thmughout the reflected sound.

WIOER IMACINC AREA.
Imaging is no longer appreciated
just in the sweet spot." The asym-
metrical offset of the tweeter on
its baffle improves imaging over

a wider listening angle. (Fig. Br

BETTER SEOMETRY = BETTER
IMACINC.

Unique narrow cabinet baffle mini-
mizes diffraction turd reflection
effects for superb stereo imaging.
New low frequency design delivers
more energy from a small cabinet
and maximum performance in any
location.

STRONC, PRECISE IMACINC.

Our ultrawide-dispersion, louvered
3/4 " (19 mm) tweeters produce preci-
sion lmalization on axis, along with
treble airiness thmughout the room.
It's the best of both worlds. Other
speakers use bezuny, 1~inch (25 mm)
tweeters. on wider cabinet fronts,
too. (Fig. Cl

BETTER REAL WORLD
FREQUENCY RESPONSE.

Here is actual frequency response
measured in a real, typical living

hi on" be

room. Note its serious smoothness
across the crucial, ear-sensitive mid
range and upper midrange. This
simply means better and more accu-
rate sound. (Any speaker system's
response below 500 Hz will vary
from room to room and speaker lo-
cation to speaker loartion.) (Fig. Dl

SPECIFIC MATERIALS CHOSEN
FOR BEST RESULTS IN EACH
DRIVER APPLICATION.

Pulp paper cones are used where
deep bass is required; rigid carbon
loaded polypropylene cones with
minimal high frequency breakup
are specified in some models to

assure smooth midrange response.

Due to the new and improved
woofers, these speakers demurr-
strate effortless bass perfimnance.
Rubber roll surrounds ensure the
greatest excursion possible for the
cone, combined with very low resr
onancc. The acoustic suspension
system that AR invented then max»
imizes the bass perfonnance from
the compact cabinet.
