In recent years several radically new speaker designs
have been introduced. Each attempts to make an im-
perfect mechanical device simulate a theoretically per-
fect speaker. Enter the MAGNEPLANAR — a unique,
important advancement, offering advantages in music
reproduction not possible in other designs.
The MAGNEPLANAR speaker combines the best tech-
nical characteristics of electrostatic and dynamic loud-
speakers with design advances that are covered by US.
and foreign patents. The MAGNEPLANAR was recog-
nized by a group of scientists in this country as one of
the most significant inventions of the year 1973. The
U.S. patent office has also recognized its technical
significance by displaying and demonstrating the
MAGNEPLANAR speaker at National Inventors’ Day in
Washington, D.C. in 1973 and 1974.

MAGNEPLANAR Tympani IB
The basic Tympani speaker. Fits most acoustical environments adequately.
Offers a maximum of frequency range and performance with a single ampli-
fier. When optimally placed in rooms approximately 12° x 18° and larger, can
provide extremely realistic music reproduction. May be bi-amplified for in-
creased sound levels. ES
MAGNEPLANAR Tympani IIIA
Designed for audio perfectionists who demand the ultimate in speaker per-
formance. A three-way system requiring two separate stereo amplifiers for
the bass and the tweeter/mid-range. Connections are available for tri-
amplification. All components in the audio chain must be of the highest quality
if the full capability of пе Тутрап! ША 15 to be realized.
Tympani [HIA-TM
Tweeter/Mid-range Panels
Individual tweeter/ mid-range panels are available for use with other types of
bass reproducers for audiophiles who plan to improve their systems gradually,
or whose space limitations preclude use of the Tympani IIIA bass panels.
Tympani IIIA-W Bass Panels A
May be added to any of the Tympani speakers for additional bass support,
or to other good speakers such as full-range electrostatics. The 4-section
bass panels deliver sound quality unequalled by any other bass unit, with
none of the “muddy” bass so common in other speakers.

*The unclipped, MUSICAL output of single amplifiers with these power ratings per channel may be
safely used (assuming the normal distribution of power in music). Sine wave testing or program
material with a large power distribution above 1600 Hz (causing the tweeter diaphram to melt) will
invalidate the warranty.
