Yamaha RX-Z7 with 4-ohm speakers

[pmart348]

I recently pre-ordered the new Yamaha RX-Z7, and subsequently realized my 5 speakers( 5.1 setup) are rated 4 ohms. I contacted Yamaha and was told this receiver only supports 4 ohm loads for front main speakers.

Can anyone help understand what issues will I have with the center and surroand speakers ? Do I need yo buy a separate 3 channel amp to drive these speakers.

My speakers are Vienna Acoustics:
Front and Center: Webern (3)
Surroand: Berg(2)

Sub: JL f112

Best Regards

Bump for a proper answer.

But if I thought the Z7 couldn't drive a 4 ohm system, I'd cancel that order and get into a solid set of separates for that kind of money. Pesonally, I think the Z7 should be fine but I'll wait to see what the real experts have to say.
