Avantgarde Trio replacing Dunlavy SC-V?

Hi folks, I have big problems with room acoustics. In my listening room there are a few very nasty room modes and I can't get rid of them. My current speakers are Dunlavy SC-Vs (sealed d'Appolito design). I'm contemplating to replace them with designs with less bass output capability, like electrostats or... horns! In the later case the Avantgarde Trios come to mind. Maybe I could do a set up without subwoofer(s), so there would be far less bass (I think in case of the AG, there is a natural bass roll off from 100Hz, which should be better for my room). What do you think? I'm aware I'm comparing apples with pears, but do you think the AG Trios could be the solution? Thank you in advance.
