I will, if I'm not pleased with the Aon3, or (the clue), a pair of which are being sent in the very near future for an in-home audition. Though I haven't heard (the clue) yet, I feel compelled to report that Lars Erickson, the man behind Sjofn Audio, is delightful to work with, and if his speakers are as good as he is witty, I'll be done with my search.
The KEF Q300 is front ported. In that price range it and the DefTech SM65 both seem like good options. (For music I prefer the KEF over the DefTech, but that is a strictly personal preference.) In your space I would be leery of speakers with side mounted drivers ...
The NHT Classic 3 bookshelf and NHT Absolute Tower are both sealed design speakers, they might also be an option. (I haven't heard them - others would need to comment on their sound.)
They are a bit above your budget, but the Ascend Horizon is front ported. A friend just got three as his LCR and I'm still stunned by the sound/detail. (He actually had the Sierra Towers LR and originally bought a Horizon as the center, but liked the sound of the Horizon so much he replaced the towers.) Ascend often has b-stock so you can get a slightly better price. (But call for that, the web page is often behind.)
I did audition the Q300, but found that they need space from the wall to avoid really boomy bass, despite the front port. The DefTech could be an option if the Aon3 don't work.

Unfortunately, acoustic panels, bass traps, etc. are out due to peacekeeping efforts in the family room! I have been thinking of asking an artist friend if she could come up with any ideas for working on acoustically transparent cloth. I might be able to "sell" the idea of art to my wife. Until then, I'm stuck with things as they are.
