Different speaker types have different sound reproduction characteristics, which 
affect their performance in a home theater environment. Crestron makes no specific 
recommendations, and provides the following information for reference purposes 
only. 

To create the most realistic surround sound experience, it is recommended that you 
match your speakers’ tonal characteristics. This is also known as ‘timbre matching.’ 

Direct radiating speakers provide a focused image, which makes it relatively easy to 
detect the general location of the sound (localization). This opposes the type of open 
sound you would expect in a large theater or concert hall. 

Bipolar speakers have drivers on opposite sides of their cabinets, wired in phase, and 
provide a diffuse sound. Sound radiates from both sides, so the sounds seem to be 
coming from all around instead of from a specific location. Because the sound is 
very open, it creates a larger ideal listening area, and speaker localization becomes 
more difficult. 

Dipolar speakers also have drivers on opposite sides of their cabinets and provide a 
diffuse sound. These speakers operate 180°out of phase and create a sound field that 
is more open than either the direct radiating or bipolar types. These speakers are 
typically used in surround channel applications, and speaker localization becomes 
the most difficult. This type of speaker is not recommended for front channels. 

Subwoofers are specially designed to reproduce the lowest ranges of audible 
sound-usually from 120 Hz down to 20 Hz. These speakers are either powered or 
non-powered. Non-powered subwoofers require an external amplifier and power 
supply. Subwoofer output typically includes the information from the decoded LFE 
channel and will include the low frequency information from the left, right, center 
and surround channels when the speakers for those channels are unable to reproduce 
the low frequency sounds, and bass management is enabled. 

Refer to the diagram to the left of this paragraph and arrange the speakers in the 
listening area according to these general guidelines. Refer to the instructions given in 
“Surround Sound System Setup” on page 26 for optimum placement. 

•  Place front speakers so their front surfaces are as flush as possible with the 

front of the viewing screen, and at an angle to the listening position of 45 to 
60 degrees, with the primary drivers at ear level. Refer to manufacturer’s 
instructions. Most recommend placement one to three feet from the wall. 

•  Depending upon the type of speakers used, surround speakers are usually 

placed slightly behind and above ear level of the primary listening position, 
approximately six feet above the finished floor.  

•  Place the surround back speakers at the rear of the listening area and at an 

angle to the listening position of 60 to 90 degrees, with the primary drivers
