Speakers that have wide horizontal dispersion


I need your advice on the best used speakers for a room that is 22 by 22 with a 14 foot cathedral ceiling. Primary listening is classical, jazz, vocal. I'd like advice on those speakers that have a wide horizontal dispersion so that someone doesn't have to sit in a precise location to hear the best sound. Budget is $1500-2,000. Thanks.

Look at omnipolar speakers (not bipoles or dipoles), such as those by Mirage. Here's a link to their site for further information.
