Lots of questions...
- have you run Audyssey yet? What does it say about speaker levels?
- You only have LCR connected?
- what's the program?
- what's the display say about AVR modes and program content?
When all is set right, a mono program comes out of the CC only. The front display should tell you which of the many modes is active, as well as what kind of signal it's receiving. "Pure Audio" and "Stereo" will only power the L/R speakers. "Mono" is all CC while "all channel stereo" is all but the CC.
Going into the AVR menus, you should find tables with speaker distance and levels as measured by Audyssey. How does your CC level setting compare with the L/R speakers? I'll wager the CC is set higher than the L/R because it's a smaller, less sensitive speaker, and Audyssey is trying to make all speakers equal. TSI400's at 91dB will be muted to match your CSR at 84dB.
You really need a bigger CC... like Polk's CS20, a good match to the towers. It won't change the relative sound levels - CC may still be louder - but it will match sensitivity, so you're no longer sending 4x the power to the littlest speaker!
