The New Wonder family of double bell Euphoniums consists of the 90I/91I, 92I/93I (see separate listing) and the 94I/95I (pictured here). These instruments all head the main bell pointing up, and the second bell facing forward. The 90I/91I are four valve front action instruments. The 92I/93I are five valve, top action instruments. The 94I/95I are five valve front action instruments. Even numbered instruments are low pitch, odd numbered instruments are high pitch.
What Conn said in 1926:
With a large bore and corresponding proportions, Conn Euphoniums provide that broad, voluminous tone which experienced artists always desire, and which is the the essential feature of difference between Euphoniums and Baritones. The breadth of tone is not gained at the expense of ease of "filling," however, for the hydraulic process of manufacture used in building Conn Euphoniums produces a perfectly smooth sound passage.
