What do the numbers and letters mean for the Conn horns? I got a Conn 6D this last Friday to play in concert band, and I can't figure out what the different numbers mean. I know there's a Conn 8D and higher numbers, but what's the difference between them?

They are just model numbers. I'm not sure what the specs are on them, but the 6D and the 8D are both double horns, the 14D is a single horn. Most people consider the 8D to be "better quality" but I always liked the tone and response of the 6D much better.

I was looking on the CG Conn website and found a brochure with all the descriptions of all the different models they have:

Nice brouchre, but it does not have the 6D listed.

The 8D is a large bore, large tapered bell horn. Often referred to as the Hollywood Sound that you hear in all the movies. Some Orchestras may require (or certainly place pressure on you) to play one. Some conductors are particular about certain sounds.

The 6D is a slightly smaller bore and different taper bell. There is a different sound altogether. Many people refer to the 6D as a student horn, but it is not a 'student' horn. It may take slightly less air to play than the big 8D. I own both an 8D (B series 1962) and a 6D (1950). Both are wonderful!! I use my 8D for symphony orchestra and operas. I use my 6D for woodwind quintet, string nonets, and small chamber orchestras.

Hope this helps you.
