ISEAT 2019 - International Symposium on ElectroAcoustic Technologies - A Report from the Center of Global Speaker Manufacturing

Loudspeaker engineers have few choices for professional forums. The Audio Engineering Society (AES) is an outstanding international organization although not entirely focused on speakers. ALTI (formerly ALMA) is loudspeaker-centric but does not have a strong base in China. And although you may not have heard about iSEAT, for most Chinese speaker engineers that is their preferred professional organization. The International Symposium on Electro-Acoustic Technologies (ISEAT), founded in 2007, is held every two years and has successfully conducted six sessions.
