I use an Essence mk2 connected to a BeoLink Passive (using a cable from our sponsor Steve).  This drives some Polk Audio Atriums (forget the model).  I like it very much.  My neighbor has some Klipsh outdoor speakers which sound awesome, but they're also huge.

There are a variety of different sizes in Klipsch's outdoor line. I would recommend them based on experience in using them in outdoor training ranges in fairly harsh environments at my last job. I was amazed at their durability and sound quality was very good. You could tell they were designed with the outdoors in mind.

You could also use the old Beovox CX range that sound great for their size and ideal in many situations.

What about the Terrestrial Line by OA/B&O? Is it already available?

Instead, because "Rooftop terrace" sounds like the top floor of a multi-family or close city dwelling neighbors, I would consider installing twice as many speakers as you normally would, and running them all at half the volume you normally would.  Thus you are creating "near field" listening in every location on your own terrace, but without making it loud enough for the neighbors to complain.  If necessary for multiple fixed seating areas, even consider a Left/Right/Right/Left configuration to create "rooms" of stereo (two in this case) with transition, rather than putting all the Left speakers on one side and the Right speakers on the other.

Thank you all for your replies. As my terrace is fully open air, not that big (10 m2) and the neighbours do not always appreciate my roommates’ music taste and volume level, I think I will have a closer look at the Klipsch landscape satellites (P500). Now to decide which amp to put between the speakers and the Core.
