Congratulations in joining the thousand of proud, satisfied
owners of quality stereo components from Sansui. The speaker
units and acoustical enclosure of the SP-3500 are entirely new
designs, containing fresh technical features:

FEATURES

Multi-directional Speaker System
The Sansui's exclusive Multi-directional Speaker
System creates the realistic atmosphere of a concert
hall or a jazz club for each listner in the room, re~
gardless of seating position. In this system, the two
horn tweeters and two cone midranges are directed
inward at an angle of 15° to the principal axis of
the speaker system itself so that their directional
sound waves are crossed in the sound field to offer
not only wide dispersion but realistic reproduction
of music.

SPEAKER SYSTEMS SVSTEMS

Woofer

The 14 woofer gives uniform response through the
lowest octave of hearing. It is also fitted with 6
massive ferrite magnet, copper voice coil and high
quality aluminium bobbin, all necessary when
handling high power of 100 watts.

Midranges

The two 4" cone midranges employ the aluminium
concave dome radiator mounted directly on the
voice coil bobbin which gives exceptionally smooth
response up to 20 kHz. The horn midrange, mount-
ed in the upper central portion, is fitted with an
acoustical lens for wider dispersion.

Tweeters

The two horn tweeters with lowest distortion and
highest efficiency are mounted at 15° to the principal
axis of the system itself to improve their directional
pattern.

PLACEMENT

As a general rule, the speaker systems should not
face a bare plaster wall, large picture window or
some similar hard surface that can bounce back
most of the sound. If so, the music may sound
shrill. One way of avoiding this is to hang draperies
along at least part of the wall exactly opposite the
speakers.
