Emerald Physics CS2.3

Considering a pair of these and looking for input from anyone that has experience with them.  I read that they are great for 'concert volume' realism but I'm not so into that lately.  I'm wondering how they sound at lower to mid level volume.  Since Covid my only listening sessions are at night when my family is asleep (and I force myself to stay up!).  So, lower level listening has become more important.  I have a feeling that these speakers might not really come alive until pushed a little.    

Also wondering how much work they are to setup given the external crossover, etc.  I've never messed with anything like this before but have been researching.  Seems my free time is more restricted than usual and I might be more of a plug and play guy.  I have 60 watt Jolida tube integrated for the highs (maybe, not sure I can use an integrated this way - probably not!) and McCormack DNA .5 for the lows.  Although I've been interested in making the shift to more efficient speakers and low powered tube gear.  I could possibly pick up a SET amp for the highs.  

Thanks for sharing any knowledge.
