speaker recommendation for 35watt tube mono blocks

I'm looking for a fun exciting speaker that will sing at any level. $1k-$3k    I'm demoing the original Klipsch Forte with Forte II mid/treble drivers and rebuilt crossover paired with old RCA amps. They're a lot of fun to blast and fill the house.  I miss however definition and detail in the imaging when sitting in the sweet spot.  It's a softer focus.  Is the Forte III also like this?    
Zu has caught my attention. 
Others?
