sound quality seems good, but I am in Chongqing, in-line to see that the South was wet, it is best not to use the cone, we do not know about his views on this?

Also heard that some people in the seaside Pener paper, not a problem.I would like to design a time when manufacturers should take into account these factors, if not the very extreme environment, it should not have.I think Members of the main concerns is not to say that because of damage to the damp, but wet afraid of the future flexibility of what has changed, the impact of voice quality.

I am in the north, very dry, so little experience in this area, Days sauna room is also open Dehumidifier air-conditioning.But I also lived in Sichuan, as long as the feel ready to serve should be careful not serious.Sichuan otherwise there would like to use a home theater or speaker HIFI has not chosen Cone of a child?

Can not be assured if only by the PP Pener.Other other materials are afraid to say that wet, but not the effect, such as paper or the PP's good.But PP basin Child is not suitable for soft sources.You do not know the election of the low-frequency part of how this kind.Not just look at indicators of parameters, have to listen.
