It is perhaps important to remember that Franco Serblin came to fame as creator of 'small' two way monitors (Extrema or Guarneri are not exactly 'small' but stil...)
Certainly many of his famous designs, made during the years, confirm his mastery in that field of work, Only later in his career and because of market demands, he started to create bigger, more elaborate speakers.
It is no surprise that he made Accordo's (two way monitor) as speaker with whom he reentered the business again
Had Grand Piano, Cremona Auditor, Auditor M, Guarneri Hommage and now Franco's Lignea.
The only reason I have not taken (yet) the Accordo' is because they have lower impedance than Lignea (which never drops bellow 8ohm) as I wanted to try them with tube single ended amp of lower wattage (30w A class, but they play great even with 15w Leben 300)
Accordo's are fine sonuding speakers, but they are voiced differently than older SF designs. (re Cremona) They can sound great with tubes too (heard them with bigger PL amp) but often they are demonstrated with Accuphase gear. If I had a bigger room, would go for Ktema as my final speaker, before any other new SF designs. Some photos from the factory
