Don't get caught up on the Studio Monitors aspect of their description. They're bookshelf speakers primarily. Why do Soundbars sound like crap and Bookshelf speakers so much better? Because depth to sound develops behind the speaker itself, in that nice box cabinet. We're recommending Bookshelf speakers over a soundbar with an active subwoofer because whatever you get in your budget for those won't sound as good as a simple 2.0 bookshelf setup for one, and for two, you need not cross your budget to get great sound. The Eris ones from Presonus are well within your budget and they're not to be laughed at, trust me.
Anyhow, your wish in the end. Since you said you care about vocal clarity and did not care so much about boomy bass, I recommended the Eris 4.5 bookshelf speakers because they exactly fit your bill. A Soundbar will deliver highs and the subwoofer, low bass, the mid-range would be mostly lost out on and therefore you end up with a boomy speaker setup that is opposite to the brief you mentioned and vocal clarity would be out the window.
