Zu audio would definitely be of interest. Any idea where I can audition them?Other than whats mentioned above
Maybe Tannoy or Kef with their concentric drivers may have something 90+db.
Else horns are the next option.
Full range driver speakers will definitely get you there.
Zu Audio is another manufacturer that comes to mind for high efficiency speakers.
Thanks. Will check this outAudionote sells pre-owned stuff of their and other brands too on their Indian website which you can take a look.
