The Meinl Weston 2141 Eb tuba is an amazing instrument. At a 5/4 size with the large valve set this horn can produce a very strong sound in all registers. The 17.25" bell adds a lot of resonance as well. Add to this the 5 valve features and you have an unbeatable combination.
The Allora AA191 4/4 4 Rotary Valve Compact BBb Tuba is well suited for any ensemble situation. The AA191 4/4 tuba features a large, full sound with excellent response and plays with the characteristics of a 5/4 instrument. The Allora AA191 includes a case and is available in lacquer finish.
The "S" version does not have the nickel-silver tuning slides and brace tubes. These are just polished and lacquered brass. This lack of nickel-silver trim gives it a darker sound. Heavier brass and valves make it one of the best tubas on the market for the money invested. Miraphone, quality throughout the line of instruments.
