How to create organic shape of this vinyl record player tube? (image included)

Sorry for bad english language, I am not a native speaker.

I don’t know where to start approach making this part. if you can provide me a youtube video tutorial that is similar to this. I would really appreaciate it!
Thanks

Basics:

Draw the shape for a section of the horn. Use a skinning extension to create the surface (I used TIG’s Extrude Tools but Curviloft would work, too.), Joint Push/Pull to give the surface thickness, Copy/Rotate to make the other nine sections. Use Follow Me with a circle and path to create the elbow.
