Primare I15, 60w 8 ohms, 100w 4 ohms, can it run 6 ohms speakers?

Thinking about the JBL L52 Classic.

Edit: Oh, they are 4 ohms. Question still stands. Recommend amplifier watt is 10-75, will 100 watt be too much?

will 100 watt be too much?

No.
(When you stick to the golden rule that, if you ever hear stress (distortion) lower the volume).

Think of the spec quoted for power output as being like the maximum speed of your car. Your 120mph car isn’t ‘too much’ for a 70mph motorway, because you don’t drive it flat out. So, your 100watt amplifier isn’t too much for any speaker as long as you are not silly or deaf, and I’m sure you’re neither!

Your amp won’t mind what nominal impedance your speakers are. It isn’t a fixed number anyway, but no need to concern yourself with that. Only the most extreme speaker designs, most of which are silly money, are troublesome to drive with any modern amp.
