The Daedalus DA-1 loudpspeakers are designed to address exactly what you are looking for. They have 2 tweeters in each channel that are at offset angles to provide a very wide "sweet area."
Even at demo/used pricing, these are a tad out of your price range. However, they do what you desire. If you can swing the higher price, you should look into these. There are several recent threads.
