INTRODUCTION
The Heathkit Model A9105 Two-Way Bookshelf Speaker
System will accurately reproduce all frequencies from 20 Hz
to 18 kHz. Even at high volume larels this System will
operate properly with negligible distortion.
A 10" acoustic suspension low frequency speaker, and a
3-1 12" high frequency speaker are used in this System. The
low frequency speaker incorporates a one-pound Alnico
magnet and compliant rubber suspension to produce low
distortion bass response over a range of volume levels, The
high frequency speaker is a ring-damped cone unit which
acts like a dome speaker at high frequencies, but uses the
entire cone at midrange frequencies. A control on the rear of
the enclosure allows you to adjust the volume level of the
high frequency speaker.
The low and high frequency speakers are mounted in a
specially designed airtight enclosure that is loosely filled
with acoustic padding. The AS-105W enclosure is enhanced
by its rich, oiled-walnut exterior. The AS-105U enclosure
comes to you unfinished, enabling you to apply a finish that
will match your decor. Both cabinets come with a removable
grille cloth front. These features make the AS-105 Speaker
System a worthy companion for any music system.
Refer to the "Kit Builderc Guide" for complete information
on unpacking, parts identification, tools, wiring, nldering
and step-by-step asembly procdur*.
