i used to own 11L and prefer them to Proac response 1sc. They are warm sounding and have considerable good midrange. I compare to LS3/5A, and their midrange is still not as revealing / effortless. Sometime it may sound a bit overblown, but it plays music beatifully most of the time.
Another aces is their agile and deep bass, which set apart from many bookshelf. Their laid back high is also seductive after listening.
It take 2 solid months for me to run in these gems.
