Nominal Impedance question (1 Viewer)

[BrianGC]

My receiver says use speakers with nominal impedance of 8ohm to 16ohm. Some speakers I was looking at say they have nominal impedance of 4ohm to 8ohm, are these compatible or will they cause trouble?

Thanks,

It depends on the efficiency (sensitivity) of the speakers and the power output of the amp.

My way of thinking regarding your question is that if a receiver says 8 to 16 ohms, the manufacturer is telling you 'hey, this thing is gonna run into problems if you go out and toss a 4 ohm speaker at it'. it's going to have issues with running out of current, clipping, distortion, shutting down due to overload condition. There's lots of good speakers that're 8 ohms. The problem is finding one you like and that suits your budget.
