Thank you for purchasing Phase Technology CI custom 

installation speakers. This eighth generation of high 

performance in-wall models features the same superb 

sonic performance as our acclaimed PC-Series cabinet 

speakers in addition to great flexibility and easy installa-

tion, thanks to Phase Tech’s patented QuickMount™ 

tool-free clamping system. The most striking change to 

the series VIII is a new look with the off-axis tweeter 

design. This feature maximizes the speaker’s clarity and 

imaging by creating an asymmetrical loading or diffrac-

tion pattern, reducing the amount of diffraction normally 

caused by a flange-to-wall junction. The net result is the best 

sonic realism you can buy in an in-wall speaker. All CI-Series 

speakers include self-resetting solid-state PTC protection 

circuits. This unique system is able to detect when the 

speaker is being over-driven and lowers the speaker volume 

until the problem is corrected. The PTC device then resets 

itself for normal operation. Other features include liquid-

cooled tweeters for greater power handling, moisture-

resistant materials in all of the critical speaker components, 

, galvanized steel speaker grilles and stainless steel hardwar

e for improved corrosion resistance, IR knockout mounts an
