Compatibility of 8 ohm amp with 4 ohm speakers?

Just because its power rating was given at 8 ohms does not mean that it cannot push a 4 ohm load. Of bigger concern is that the speakers may be 4 ohm nominal, but may dip down lower at some frequencies. Many planar speakers do drop down to 2 ohms or less, and require large amounts of current. OTOH, If its a steady 4 ohms and the minimum power requirement is well within the rated capacity of the amp at 8 ohms, you may be OK. Older Nikko may not be able to deliver enough current, tho, to make the Maggies work to their capability.

Thanks,good informative answer.

Typically I'd expect the marketing people to publish the amp's 4 ohm spec if it had a good one.

Thanks, I have received alot of good info from this forum and other sources. I think we are going ahead on the purchase.

Kvack, I'm not sure how you read this, but, I don't recommend this combination and I don't think any one else has either!
