Hi all,
I just got a few new engines lately and one in particular is a brand new Lackawanna heritage unit. The issue I have is that when the sound is on, it sounds scratchy making me think of a blown speaker. However, When I hold the shell down, it goes away. I have tightened every screw holding the shell on and holding the speaker in place. Is there an easy fix for this instead of sending it in? I am thinking about putting foam or something inside to try and reduce the vibration. Open to other ideas.
Thanks!
Sounds like the shell is used as a baffle. Is the speaker actually in a baffle? All my diesels have a baffle for the speaker.
Usually a blown speaker would have no output. I have done audio work for years.
I tried looking up Lackawanna heritage unit in the diagrams page but no luck to see what the speaker set up is like. I used, find in the page option.
I suspect it is in the fuel tank.

The speaker is located in the fuel tank. I dont want to take it apart anymore than I already have. I might just get a new speaker and see if that fixes it or not. If not, then I might try to fill the fuel tank or move the speaker location.
