Question about Avalon Opus

I have a nice offer, an Avalon Opus speaker, it look very new. My question is if my Power amp can fully handle this speaker?

Electrocompaniet AW-180 Mono-Block

And my Pre-amp is Electrocompaniet EC-4.8
By specifications alone yes. You really won't know, however unless some has such a set up, or it has been demo ed at a show or shop. Do you think Avalon can help? They usually will tell people that a pretty wide variety of amps can be used with some minimum output power.
