Budget speakers for near-wall positioning

Looking for speakers around the $500 mark for an office system. They would have to be placed close to the wall. Wharefdale Dentons look great and are now heavily discounted, but are rear ported. The Wharfedale Diamond 225s are cheaper but at least front ported. Anything else in that price range I should consider? I don’t know of any acoustic suspension designs in that price range.
