Greetings everyone, Just wondering if anyone might know if the mid-bass drivers and tweeter in the Calliope centre channel are the same units found in the standard Calliope 2-ways? My Calliopes are the 1st gen versions with the 'woven' type mid-bass units. I realize that TAG upgraded and changed those drivers at some point so my question may be hard to answer. I discovered a centre channel for sale locally but the grille doesn't seem to want to come off easily and I don't want to bugger it up by trying to remove it. Hence my inquiry. Thanks very much for your time. Any and all help and input will be greatly appreciated.
