Thank you very much for choosing Yamaha products.
It has recently come to our attention that some parts of the cabinet of the Yamaha VXS8/VXS8W/VXS5/VXS5W speaker system will deteriorate when the speaker is used in an environment exposed to large amounts of theatrical smoke or oil smoke. Due to the structure of the product, continuing to use the speakers in these situations damage the mounts on the baffle surface*1. If all mounts break, the internal speaker parts including transducers will drop from the cabinet, which may cause a serious accident.
If the speakers have been used in an environment exposed to large amounts of theatrical smoke or oil smoke or if the cabinet has become sticky, please stop using them and avoid standing/sitting below installed speakers.
For more details, please contact the Yamaha branch or dealer. We will strictly maintain the confidentiality of any personal information which we may ask in this case.
