If you have no issue on keeping your current surrounds I’d try out some other mains first before changing them. Many people successfully mix and match surrounds from other manufactures than their mains. Their distance from the mains and usually different material playing from them hide most tonal differences. The only time I’ve been bothered by tonal differences in surrounds I’ve used is during gaming when there are hard pans going 360 degrees around the room.
BTW subwoofers are not speakers. They are end-tables nice corner tables for lamps…
Come on, there’s gotta be some angle you can work.
