sidewall, progressing between the two pieces of tape.  As above, listen 
for the point in the room where your voice transitions from bass-heavy 
and diffuse to neutral.  Mark this point with tape.  Continue your progres-
sion until there is an obvious interaction with the opposite wall in front 
of you and mark this point with tape.  The four pieces of tape now form a 
rectangle that establishes the Zone of Neutrality for the loudspeaker lo-
cated on that side of the room.  Using the four marks as your guide, tape 
an outline to define the boundaries of the rectangle. 

6.  Repeat this process for each speaker location individually.  These are 

your Zones of Neutrality, one for each channel.

Theoretically, the Zone of Neutrality for any room runs like a path, parallel to the 

walls all around the room.  Adjacent to very large windows and open doors, the outer 

edge of the Zone of Neutrality moves closer to the wall and becomes wider.  If you 

were to extend the inner and outer boundaries of the Zone for the sidewalls and the 

front wall (behind the speakers), they would intersect.  After you complete this proce-

dure for the other loudspeaker, you will now have two rectangles, one on the floor on 

either side of the room.   

Section 3.2 - Room Acoustics

Note: The following section contains general information on room acoustics and loud-
speaker/room interaction. The concepts outlined below are equally relevant when 
dealing with multi-channel audio or home theater.  The careful application of these 
concepts, as you evaluate the acoustical characteristics of your own room configura-
tion, will allow you to optimize the performance of your WATCH Dog Passive Sub-
woofer.   

Slap Echo

Probably the most obnoxious form of reflection is called “slap echo.”  With slap-

echo, primarily midrange and high frequency sounds reflect off of two parallel hard 

surfaces.  The sound literally reverberates back and forth until it is finally dissipated
