I'll need to send back my BA4F to Phil. I've an issue with the left one. The right is louder. When you listen to music or watch movie, it's a mono sound with all voices on the right. If think at least one on the driver is not working. It's like there is no treble.
I sent an email to Phil. I'm waiting for his answer.
Sorry to hear that. I hope he can find a nice solution for you mate.
