hi ky1mag,
in the overwhelming majority of cases, having no sidewalls is a major advantage, not a disadvantage. looking at your room dimensions, tho, in your case, you have only 13' to squeeze you and the speakers between the front and back wall. this is nightmarish, to be honest. you said you're about 8-9' from the speakers, which means barely 2' behind you, and the speakers are barely 2' from the wall behind them. that's an especially difficult task for your present open-baffle speakers, even more so than the tektons. while i'm glad you're enjoying them, there's no doubt in my mind that they (or any speaker) would sound better if you re-oriented your room 90 degrees so the speakers fired down the length of the room. even if your living area is in the middle of the room, and you have +/-10' in front of you and behind you, it will sound so much better. if you can do it; i know how logistics are, sometimes - ha!
and, even if you're enjoying your present sound (and i certainly hope you are) i still strongly suggest trying to toe in your new speakers as i previously suggested. it besides the treble issues, it very well may alleviate some of the sound dispersion issues presented by your head being so close to the wall behind you, if you don't have massive sound absorption panels behind you; or even if you do, for that matter. and if you don't have absorption panels behind you, you should consider it, if it's logistically possible; it would be a good idea, with your room's set-up. ;~)
