Dunlavy SC-I vs. SC-I/AV

Does anyone know the difference between these two models?
(I have SC-IV/A mains and SC-I rears. Now I have an opportunity to acquire an SC-I/AV for a center channel speaker.)
I believe it was just a shielded version of the SC-I, but I'm only going from memory here. Perhaps, if no one else posts, you could ask the folks at Audio-Video Logic in Iowa, who were a major dealer and took over most of the company's inventory.
Rcprince is correct - the A/V is just a shielded version of the same speaker.
