Applications/Configurations
Floorstanding & Bookshelf Loudspeakers
To enjoy the most realistic stereo image and lifelike sound,  
place the speakers so that an equilateral triangle is created 
between the speakers and your favorite listening position.  
Angle the speakers toward the middle as necessary in order  
to support a more solid center image. And experiment with  
the distance between your speakers and both the back and  
side walls. You’ll experience some bass boost with the  
speakers located close to walls.
The LSiM Series bookshelf loudspeakers were designed  
to provide excellent performance on a bookshelf or placed  
on a floor stand. For best results place LSiM bookshelf  
loudspeakers so the tweeter height is within 6" (15cm)  
of seated ear height. 
When using speaker stands,  
select sturdy stands 30" - 36" (76.2 - 91.4cm) high. 
If you are using your LSiM Series bookshelf loudspeakers  
as rear channels in a home theater system, they should be 
placed on the rear or side walls, slightly above (and, on the  
side walls behind) the listening position. Angle them toward  
the listening area if possible. 
Center Channel Loudspeaker
With today’s modern flat panel TVs, the most popular  
placement, and our recommendation for your center  
channel speaker, is beneath your TV screen. You may  
also place your center channel above your TV should  
you choose. 
LSiM center channel loudspeakers are  
very heavy, and we do not recommend wall mounting  
them, unless placed on a sturdy shelf.
Note: 
If you have an older model television, you  
could experience a color shift or image distortion  
in your TV’s screen. If that is the case, move the  
speaker away from your TV.
F/X Surround Loudspeakers
The LSiM Series surround loudspeakers must be wall- 
mounted, either on side walls or rear walls; they have  
built-in wall mounting keyhole slots. Mount the loud- 
speakers 6-8 feet off the floor. If you’re setting up a 7.1  
system, mount the Surround Back Left and Surround  
Back Right loudspeakers at the same height as the  
Surround Left and Surround Right loudspeakers.
Make sure the material on which you plan to mount the  
speakers (plaster, drywall, paneling, stone, etc.) can support  
the weight of the speakers (LSiM702

 Surround Loudspeaker should be  
oriented so that its Dynamic Sonic Engine (3 1/4" mid-range  
and 1" Ring Radiator tweeter) points toward your listening  
area. Therefore, the F/X surround loudspeaker that would  
serve as the right surround on a sidewall will become  
the left surround on a rear wall.
