santope Posted February 12, 2013 Share Posted February 12, 2013 I am not sure what you mean by vibration sound and what is the relation with distance from a wall.Anyway, my speakers sound perfectly normal.Before I had a Casio WK 1200, which had a distinct vibration from the metallic grill over the left speaker, due to the grill being improperly attached. I disassembled the keyboard, but could not fix it, as there are no screws attaching the grill. Anyway, this is a totally different keyboard from the PX-350. As I said, I get no strange noises in the PX-350. Quote Link to comment Share on other sites More sharing options...
marylaf Posted February 12, 2013 Share Posted February 12, 2013 No problem here either at any volume level. Return it and have it replaced? Quote Link to comment Share on other sites More sharing options...
cpcohen Posted February 13, 2013 Share Posted February 13, 2013 Other people have complained of this problem, on other forums.. . . There may be a wire inside the case, which is vibrating against the loudspeaker.Your choice:. . . Return the keyboard to the dealer, and get another one;. . . Take the keyboard apart, find the wire that vibrates, and use glue (silicone sealant) to hold it down.I do _not_ have this problem with my PX-350, and I can't tell you how to take it apart..

Mike Martin Posted February 28, 2013 Share Posted February 28, 2013 Do not take it apart. Either call Casio service or your dealer. It has a 3 year warranty but I would suggest you get it looked at now. Quote Link to comment Share on other sites More sharing options...
Jetwoman Posted April 1, 2013 Share Posted April 1, 2013 I am getting a vibration that may or may not be from the speaker - it sounds almost like it is the casing vibrating. Very inconconsistent, short duration, quiet. Listeners don't hear it, but I do. Produced by bass notes on grand pianos - below middle C. Not sure whether to return unit and try another.

pianicaman350 Posted April 2, 2013 Share Posted April 2, 2013 I noticed when I'm not playing and I press the sustain pedal it sounds like there's an air leak inside. Probably part of the system, but strange. Quote Link to comment Share on other sites More sharing options...
Sudharshan Kaarthik Posted July 7, 2013 Share Posted July 7, 2013 I had the same problem after assembling it myself. I disassembled it and assembled again (tightening the screws a bit more). The vibration was gone. Check the assembly before you send back. You can check that by placing DP on a softer surface like bed. See if there is vibration (will be a little less but you can tell).

Probably part of the system, but strange.That's probably the (simulated) sound of the (simulated) dampers lifting off the (simulated) strings. Try it on an acoustic piano -- you'll get a similar sound. It's called "damper resonance", and it's a feature of the PX-150 (and related models). .
