Wessex Duplex Euphonium EP105PS Silver-gold

A silver-plated double-bell euphonium with gold and two distinct sounds

The Wessex Duplex EP105PS Silver-Plated Euphonium with Gold is one of Wessex's most distinctive designs. Its defining feature is the double-bell system, which allows players to produce two different tonal characters within a single instrument using a fifth piston.

The 300 mm main bell delivers the traditional euphonium sound, with a broad, rounded and deep tone. The smaller 216 mm auxiliary bell produces a more direct, brighter and focused sound, with a character closer to that of a baritone or trombone.

Switching between the two bells is achieved through a fifth switching piston, which redirects the airflow. This mechanism allows musicians to alternate quickly between two contrasting sounds during performance, without changing instruments or interrupting the musical phrase.

The Duplex also incorporates a four-piston compensating system. Its bore measures 15 mm through the first three pistons and 16.8 mm through the fourth. A large-bore leadpipe completes a configuration designed to retain the essential characteristics of a euphonium.

This version features an elegant silver-plated finish with gold , creating a distinctive appearance that clearly separates it from the lacquered model. It retains the same mechanical and tonal specifications, with a weight of 5.5 kg.

Benefits of the Wessex Duplex EP105PS Double-Bell System

The main advantage of this euphonium is the ability to produce two distinct tonal characters with a single instrument. The larger bell provides the traditional euphonium sound, while the smaller bell offers a more focused tone for solo passages or sections requiring greater clarity.

The fifth switching piston allows these changes to be made during performance. This feature expands the player's expressive possibilities and is particularly interesting for contemporary repertoire, wind bands and ensembles seeking contrasting tonal colours.

The compensating system helps improve intonation with certain piston combinations, especially in the lower register. The Duplex therefore retains the capabilities of a compensating euphonium while adding the versatility of its exclusive double-bell construction.

Its silver-plated finish with gold creates a distinctive visual presentation, particularly appealing to musicians looking for an instrument that stands out through both its construction and appearance.
