Bose 501s - Manual (Page 3)

I. INTRODUCTION
Thank you for purchasing the BOSE 501 SERIES II DIrect/Reflecting® speaker system. Your BOSE 501s are the cul­
mination of many years of research and dedication to the art of bringing superb musical reproduction Into your
home.
The BOSE 501 utilizes two speakers radiating toward the rear wall making speaker placement important to the 501 's
overall performance. This difference In design and placement contributes directly to the new level of realism of
music reproduction achieved by the 501 speaker system.
The detailed instructions on placement of the loudspeakers are important for you to follow, as this is the only way
you can obtain the full benefits of the 501's unique design. PLEASE TAKE THE TIME TO READ THIS MANUAL.
When properly installed, your 501s wilt provide a new dimension of listening pleasure.
II. UNPACKING YOUR 501s
The BOSE 501 speaker system Is packed in a single carton. Unpack the speaker carefully. Save the carton and
packing materials for possible use later. If the speaker appears to be damaged when you unpack it, do not place the
speaker in operation. Repack the speaker In Its original carton and notify your dealer immediately. (See Secton IV.)
III. INSTALLATION OF YOUR 501s
A. Speaker Placement
The BOSE 501 is a floor standing speaker which produces both direct and reflected sound. This loudspeaker
achieves much of Its realism by using the wall of your listening room, just as instruments in a live
performance use the back wall of the stage to project sound toward the listening area. Figure 1 shows the
arrangement of the speakers and the wall. This reflecting wall ideally should be made of dense solid
substance such as wood, brick, cement block, plaster or sheetrock. Substances such as pegboard, cork or
acoustical tile make ineffective reflecting walls.
