I don't know how they are designed to be a "multi use" speaker, but it's Athena themselves that say they designed the C1 this way. Thats good enough for me.
No, the wire inputs do not rotate, but the "Athena" emblem on the front grill does rotate so it's straight no matter how you place the speaker!
You'll be very happy with the 3 C1's as your LCR.
