I've had the X2s for over a week now and they have hardly broken in yet but they are the best speakers I've had to date. I'm limited in the space I have in my dedicated listening room (~15x20), so mostly had stand mounts or smaller footprint towers such as the Totem Tribe Towers in the past.
Up until now I've always wanted a speaker that can reproduce percussions well.
I consider myself a bass head and the Borresens are quite incredible in how much bass they can fill a room. Even with my sub turned off it still produces bass with authority. The best part is the bass such as the kick drums are a punch to the chest which is exactly the sensation I'm looking for. The quality of the bass is fast, articulate, and amazingly deep.
Can't wait for them to open up even more with time and additional placement/positioning to fully lock them in.
