I am using these for two channel music. My amp is hooked to my music server (a Windows PC). I was preparing to measure my room response. I have a tone generator software and set up a sweep from 20Hz to 200Hz, 180 seconds. With a stopwatch in hand, I wanted to check the integration of the 14" sub with the 8" Ti mid bass driver. With a light touch on the 8" Ti driver's surround I can tell there is information below 80Hz getting to the mid bass driver. At around 60Hz, both the 14" bass driver and the 8" midbass driver feel as if they are equally active. The stack is set up normally supposedly using the 130Hz crossover point between bass and midbass drivers. Does this sound normal? I guess I figured that below 80Hz I would not detect any response from the 8" driver.

Thanks. Mike
