Same here. The dynamic bass creates a very artificial booming sound. I press the "Sub" for 2 seconds as indicated by the instructions, it goes off and then it returns ... I don't know how. It would be nice to get rid of this feature permanently. It ruins the experience. I don't even know if it is on or off, I have to experiment with the remote to make sure.

I am located in Athens, Greece. I have to contact the distributor. The source is my laptop. I use both USB and Bluetooth connection. I prefer USB (less compression). I also tried my mobile phone via Bluetooth. It seems, but I am not really sure, that the Bluetooth sound is more balanced than USB sound.

tried more than one. Same symptom. The sound from the right speaker is dull, not colorful

Hi, Just installed a set of self powered speakers R51 PM. The speakers are connected to my laptop docking station via USB. My problem is that the sound is biased to the the left. This is annoying. I mostly listen to music and the left speaker is more loud. Settings, balance are ok. Do you have any idea of the source of the problem ? Thank you in advance. Panos
