Kef also has a concentric technology in their uni-q drivers. Kef makes excellent speakers is an English company an has affordable models utilizing the uni-q technology at a far more affordable price point than wharfedale.Check ebay they have a new satelite wall mountable uni-q for less than 100 dollars.http://cgi.ebay.com/KEF-Hts1001-2-Bookshelf-Speaker-w-Wall-Bracket-Each-/130516799735?pt=Speakers_Subwoofers&hash=item1e636850f7 Chris Boozer
