I have a great Pioneer component stereo that is about 25 years old but the speakers are shot.  I am looking for a new pair of speakers and am considering Bose 301 as they have a similar size and color.  I am concerned that the ohms are matched poperly and would appreciate some guidance.  

The Pioneer amp says on the back that the speakers should be 8-16 ohms.  The original Pioneer speakers are 8 ohms. The Bose speakers are rated 4-8 ohms.

My question is whether this is close enough of a match?

Thanks,

Brian
