Powered Bluetooth speakers under $600

I have a very nice setup for my primary system, with Golden Ear Triton one speakers.
I just bought a Bluesound node 2i (no internal amp) to start enjoying streaming, Qobuz, internet radio etc. Of course I can plug that into the back of my amp.

But I would like to buy a pair of powered speakers that would sit in my library, and use the node 2i via Bluetooth connection to those speakers. I know I will not get the sound of Triton One’s that are in my living room; but I would like pretty good sound, with bluetooth connection from Node 2i to the speakers. And some reasonable amount of bass. No need to shake the walls at all. 

I am willing to spend up to $600 for the pair. I have read about Kanto YU5 and YU6, Klipsch 51 (Lowe end is only 67 Hz?); These days, challenging to go into a store to listen to and compare speakers.

Does anyone have suggestions for a pair of powered bluetooth speakers for $600 that will be satistfying without the need for a subwoofer? I guess I could spend a bit more if it would bring sound to a new level.
Thanks.
