I agree the Linkwitz site is a good guideline for two channel systems and dipole bass. It wouldn't hurt to read but at the same time it doesn't address your issue directly.
I have helped with the construction of the Orion and it is a very good speaker. But its more than you mentioned you wanted to spend and somehow (from experience) may require component complexity you won't desire.
And I challenge Didactilly to suggest a speaker that fits your description and fits your price range. Since we know its very easy to vaguely criticize when you don't feel morally obligated to offer a hard solution at the same time.
Yes I am offerring service, because no one has come up with a solution yet and my commercially available ones didn't seem to resonate well.
