Conn 11D & 11DE Review

The 11D is a medium sized Geyer style horn that provides a bit more openness of tone compared to its small-bell cousin the Conn 10D. Both of these "open wrap" Geyer horns by Conn contrast with the more widely known and larger "closed wrap" Conn 8D, emphasizing tonal focus and ease of control over the large sound produced by the 8D. Within the price range and style, the Conn 11D and 10D's key competitors are the Yamaha 667 and the slightly more expensive Hoyer G10. So how does it stack up? Conn's Geyer style horns--a design that's increasingly popular across all manufacturers-- have not gained the same popularity as the Yamaha 667 Geyer horns, in part because the Conn 8D overshadows them as Conn's legacy brand.

But they have developed some traction. Canadian Brass hornist Bernhard Scully has played on a gold-plated 11D, which helped give the model some visibility beyond the usual Conn 8D audience. While the horn design is solid and quite similar to much more expensive horns, players say the build quality is hit or miss. Some have reported some sloppy manufacturing practices, as highlighted in this video from Houghton Horns.

Typical of Geyer-style horns, some notes in the high register are squirrely - a sacrifice many are willing to pay for other benefits. On this horn, the Bb above the staff can be difficult to produce with the standard trigger + 1 fingering. But lower horn players should be pleased with the 11D's comparatively open and clear sound below the staff, which is better than many higher priced Geyer-style horns. Learn more about Conn horns.

If transitioning from a Kruspe-style horn, we recommend trying the rose brass bell version which offers a more similar dark sound than the yellow brass.

UPDATE: The 11D was replaced by the 11DE. Improvements include a redesigned F branch, offering a more open sound. Other cosmetic improvements a new adjustable pinky hook (a big plus for players with smaller or larger than average hands) and two spit valves. Once we have a chance to play this redesigned horn and get player feedback, we'll update this review.

Cost: Before discontinuation, the 11DE sat in the mid-priced professional factory-horn range; check current used-market pricing.

Also consider: A similar horn with fewer manufacturing complaints, the Yamaha 667 is a very popular Geyer style horn.
