Sorry, I left my comments on a down note which might exaggerate how I feal about these speakers. I like these speakers, and I think they are very well balanced tonally with a sub or boundary reinforcement. I'm just struggling to find a use for them right now which keeps them in their comfort zone volume wise.
Yes, I agree these are great nearfield.
I have measured several of my speakers. In similar or smaller sizes: B&W601S3, Dali Ikon OW, and Erin has measured the Vanatoo Transparent One which are my current nearfield speakers. I'm afraid to share the figure below because I'm not interested in doing a detailed comparison of these speakers and I don't want this figure interpreted as a value statement in anyway. Each speaker has their pros, cons, and tradeoffs. The Zaph 5.2 are good speakers and very well balanced, but they do have higher distortion in the 100-200Hz region than some similarly sized speakers. To my ears, this crosses an acceptability threshold at times.
All at 95 or 96db @ 1m. Zaph 5.2 in red, B&W 601 S3 in blue, and Dali Ikon On-Wall speakers in green.
