XPA-3 with 4ohm fronts and 6ohm center

[ac2011]

Hi - I'm starting the research for a new speaker purchase plan, likely in a few months. I currently have all 8-ohm speakers and I use an XPA-3 (Gen 1) on the L/C/R.

One brand that I am looking at indicates the floorstanders are 4-ohm, while the center channel is 6-ohm. When powering this combination with the XPA-3, won't there be a mismatch in power directed to the floorstanders vs. the center? It has been my understanding that the L/C/R should have equal power (as well as the same tonal qualities) for best sound - but perhaps I am incorrect.

Also, the company's website indicates that the floorstanders and the center have 400W max. power handling - I believe the XPA-3 is under this maximum even at 4-ohms (Gen 2 specs say 330W). Thus, if I did go with these speakers, is the XPA-3 going to be enough for them? I don't listen at reference levels by any means, but presumably any "headroom" would be non-existant?

No problem. That's what level controls in your processor are for.

A few things to note. The XPA-3's can definitely handle it. You would need level matching which can be done on your reciever.
Those speakers are also rated to keep in mind wimpy reciever ratings. Your XPA-3's are a lot more powerful than you realize
I drive my axiom m80's with an old UPA-2 (not upa-200). It is rated for a maximum power of more than twice what the UPA-2 is capable of delivering. But I have quite a bit of headroom Granted an XPA-2 did sound better. But the UPA-2 didn't faint in a side by side comparison

Plain and simple you won't have any issues

Since most normal listening is done around 1 watt, you will have plenty of headroom leftover. You want to look at speaker sensitivity to determine headroom, not the speakers max power handling.
