    iw60 efx help | In-Wall Speakers

    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!

      PedroRodrigues Hi JD23 when using the Tannoy iW60 EFX I would recommend having a Amplifier Power that offers the following power and impedance 100 - 200 W @ 8 Ohms and power handling of Average 100 W; Programme 200 W; Peak 400 W so you must look for power amplifier that offers these specifications to avoid any issues. Thank you

      JD23 Thank you for the reply. I am wondering how to make the speakers 4 ohms vs 8 ohms. Aside from the normal red and black pair of banana plugs, there is a green connector on the back with a place to insert 4 wires and set screws to tighten down on them. The holes are marked two with a plus and two with a minus. Does this have something to do with the resistence?
