Just moved to a new home and I now have a dedicated music room. I still want to run dedicated 20 amp outlets and paint. I started setting things up temporarily, just so we could hear a little music. We moved half way across the country and there is still a lot of work to do. Once we are finished unpacking, I will be able to concentrate more on the music room.
The only way you will find out is if you get a horn of your own.
No seriously, I have no idea. The horn goes with an antique 1920's walnut table radio we have. It was just set there so that it wouldn't get damaged while we were moving stuff. The same as with the Bob cat.
