Location Options
Home Theater LCR – The ICTS-6 LCR makes an excellent choice for 
the front-channel speakers in a high-performance home theater system, 
even when near total invisibility is a primary requirement. Their directed 
soundfield means you can “aim” the frequencies toward the listening 
area, for superb sound without any visual compromise.
Stereo - The speakers are perfect for delivering full 2-channel stereo 
sound in any room, giving you great sound quality without any visible 
speakers. This is ideal for any room where you can aim the sound at the 
listening position such as dens and dining rooms. 
High Frequency Level Control - This 3-position switch (–, 0, +) allows 
the speakers’ high-frequency balance to be tailored for reflective, 
normal, and absorptive acoustic environments. This means the speakers 
will always sound “right,” whether the room has hardwood floors and 
glass sliding doors, or thick cut-pile carpeting and overstuffed furniture.
Features:
• Heavy-duty 6 ½” woofer delivers great bass and natural midrange 
• Atlantic’s exclusive LRT™ (Low Resonance Tweeter) Technology
• Tweeter level control to match the speaker to the room’s acoustics
• Pivoting tweeter mount allows precise sound directivity
