Hi Chris - Wharfedale has had a speaker line out in the states for a little while called Pacific Evolution. The line includes both floor standers and stand mounted speakers. The price range seems to go like this:

evo-8 $400
evo-10 $500
evo-20 $600
evo-30 $800
evo-40 $1000


Their US distributor (IAG America) has a pretty good description of the speaker line:

And a brochure:

I would categorize these as "Main Speakers".

I have a pair of the Pacific Evolution 30s & have a few good words to say about them.

Since IAG also works with a large number of dealers nationwide, I would wager that there are a number of others who might have something to say too.

Cheers, Gary Bergstrom
