Anyone with info about new d&b system. In video they claim up to 24db rear rejection and they mention full bandwidth. Fulcrum FL283 has 10db rejection in the low range. What I'm interested in is this the same passive (sub)cardiod technology? I think I saw a youtube video with Dave Gunness mentioning their technology is patented.
