can harbeth speakers play loud

hello,
I'm considering upgrading my speaker setup from my sonus faber grand piano (home) to harbeth 40.1's. I'm wondering if they will play as loud as my sonus fabers without hurting the speakers or the sound?I'm not trying to recreate a rock concert I just wanna be able to crank em every now and again without having to worry I'm gonna hurt something. I heard the harbeths are made to really show they're strengths at lower volume levels. thanks for any input.
