Last year at the Burning Amp Festival I heard a pair of open-baffle speakers that I found very impressive. They were tall, with 7 drivers in a D'Appolito configuration on beautiful hardwood slabs. The most natural sounding bass! A plucked acoustic bass sounded like real strings, not "thuds." Midrange and highs were lovely too. Imaging was excellent, IMO. They were made by a fellow named Greg Prisament and called "Natur". He has a web site but I don't know if he's taking orders. Previously I've heard smaller, single-driver OB speakers (some DIY and some commercial) and they were pleasant in many ways but wouldn't do orchestral music to speak of. These were speakers I could live with. I'm hoping he'll be there again this year, I'd like to hear them again.
Open baffle speakers
Open baffle speakers design is the simplest , to get bass response similar to other design , like ported, the baffle size must be huge to avoid low frequency degradations . Tipical size the baffle width 10-20" got weak bass performance. I am wondering how open baffle speakers design became so popular ?
