A couple of years ago, I bought a house that had a theater room in the basement.  The previous owner left the rear speakers installed in the wall.  I pulled one out and learned they are Tannoy iw60 efx boxes.  I found the manual online.  I'm a speaker noob.  I read the cinema mode is 4 ohms while a music mode is 8 ohms.  My receiver only goes down to 6 ohms.  So, I assume I need the speakers to be in music mode.  I have no clue how to do this.  I would appreciate any help.  Also, advice on whether these will be good rear surround speakers would be great.  Thanks!
