Yes, the HB is too deep. On most of my sound installs for modern diesels, there is room for a 28mm HB speaker in the cab area, if all the details are removed. Kato and Athearn RTR locomotives are good candidates for install of the 28mm, not the Genesis SD70ACe/M-2.

I couldn't fix your brakes, so I made your horn louder
Is the High Bass speaker too deep?
A 1.1" High Bass Speaker will not fit in these locomotives. Add the 1.1" round in the existing enclosure behind the cab, and add a medium 34.7mm x 20mm oval speaker with enclosure under the rear radiator. Sounds superb.
Or better yet, get a 1.1" round High Bass speaker.
Hi OHC-
Use a 1.1" round speaker. You can order them from http://www.tonystrains.com/
For a complete install on the Genesis SD70ACe/M-2 check out this series I did: http://www.youtube.com/watch?v=hQXiEYfE4C0
I just bought a tsunami decoder for my athearn sd70m-2 and I am not sure which speaker would be the best. Isn't the enclosure 1 inch and what recommendations do you have for a good speaker?
