I have heard the Zonas. To be honest, I was expecting so-so quality sound because of the potential for RF interference and their surprisingly small size. That notion was quickly put aside after hearing them at my good buddy's house. (By the way, he wrote a review of them over on Audioholics.) The Zonas were the equal to many fine stand-mount speakers I've heard. It is not far off from the highly touted Ascend Sierra 1. It also seemed pretty flexible with the remote tone control. It can carry more bass weight than any other speaker I've heard in this size and class.
Pretty amazing speakers for the price, IMO.
Disclaimer: I don't own a pair of these Zonas, tho' I do own a pair of their Intimus 4B's and a Bravus 10D subwoofer (as well as Aerial Acoustics, ACI, JBL, Nates Audio, and SVS speakers and subs). I think Aperion offers really good quality for the price. These Zonas aren't going to squeeze out the very best detail, but they're pretty darn good and the wireless feature makes positioning them a breeze.
I hope this helps.
they're not just for breakfast anymore.
