Hi Zavato,
Yes, recommendation... start with the perfect triangle set up... Meaning if your speakers are 8 ft from your ears, make them 8 ft apart, then use a full tow... On Revel F30's, point the midrange directly at your ears. This formulation helps remove the room acoustics from the picture... If you have the need, you may reduce your tow a bit, but now you have the issue of no back wall reinforcement, but I suspect as long as you don't completely remove the tow in, You will still have good results. As far as changing your equipment... feel lucky that you don't have that disgusting virus that makes you want to change everything every few month... No matter how you look at it, there is always something better. If you want a different flavor, I would consider changing speakers, but they are proven performers. They go done fairly well, but as you, a subwoofer as always improved my soundstage also, Good Luck brother, let us know how it goes, Tim
