A Legacy of Boston Craftsmanship: The Powell Sonaré 705 Series Professional Flute

Crafted for the uncompromising soloist and advancing virtuoso, the Powell Sonaré 705 Series Flute (Model PS75BOFTR) represents the absolute zenith of modern step-up flute engineering. Marrying the renowned, signature acoustic resonance of a Boston-made handmade headjoint with contemporary mechanical perfection, this instrument is meticulously optimized for elite symphonic players, soloists, and conservatory performers who require an authoritative, deeply expressive sonic footprint.

The visual and acoustic hallmark of this masterpiece is its remarkable Sterling Silver execution. Both the body tube and the hand-cut Signature II headjoint are manufactured at Powell's legendary Massachusetts workshop, utilizing a choice .016-inch medium tubing thickness that allows a brilliant, deeply centered resonance to emerge across all dynamics. This striking acoustic core is beautifully contrasted by a high-precision, silver-plated nickel-silver mechanism featuring open-hole French cups, resulting in an instrument that commands physical attention long before the first note is played.

Unrivaled Resonance & Acoustic Architecture

The legendary voice of the Sonaré 705 is realized through the integration of the Modern Powell Scale and a hand-cut custom headjoint, which accounts for over 50% of the instrument's total acoustic output. This sophisticated inner taper alters how air responds across intervals, yielding a remarkably full tone and powerful projection that handles complex standard repertoire with absolute ease. Elevating its performance further are precision-drawn tone holes and an extended B-footjoint featuring a standard gizmo key, optimizing lower-register response, stability, and tonal focus.

Bespoke Ergonomics & Fluid Mechanical Action

• French Pointed Key Arms: Features an elegant pointed key configuration that distributes finger pressure directly to the center of the key cup, providing an airtight pad seal and a significantly crisper, more unified tactile feel.
• Offset G & C# Trill Key Assembly: Designed around an ergonomic offset key layout to prevent wrist fatigue, paired with a highly responsive C# trill mechanism to ensure instantly fluid, worry-free execution of complex technical trills.
• 10K White Gold Springs: Outfitted with luxury-tier 10K white gold springs—a feature typically reserved for elite handmade flutes—to deliver light, snappy key response and exceptional long-term mechanical resilience.
