Also somehow I began to rattle speaker, or where not found the information that this may be due to dirt, so it was decided to change. At the same time I changed the battery pack, thinking that she, too, is broken. As a result, neither the speaker nor the battery Jordania did not pass ..
A year later, brushed mesh and studied branch power, the sound is clear and the battery keeps excellent. Try to clean indiscriminately tooth brush, or if there is to be thinner and more fluff blowing. I would have tried the compressor, there is a speaker at an angle if necessaryPost has been editedBogdan324 - 06.07.20, 23:06
