Polaris Adjustable Clarinet Barrel

The Royal Global adjustable barrel features an innovative patented adjusting system combining a premium aged grenadilla wood bore, Royal's proprietary ECO-wood material, and a new, heavier brass internal mechanism selected for its superior acoustical properties and longevity. This combination allows for a more durable, crack-resistant barrel that is easy to maintain. By manufacturing the top section and bore with grenadilla wood and the base with the new grenadilla ECO wood, the Royal Global adjustable barrel maintains a wooden bore that helps achieve the warm, rich, vibrant tone with depth. Choose the Corbin Traditional Bore for a slightly larger bore with a Moennig-style taper for a centered, colorful and focused tone with more upper partials compared to the stock bore.

Upgraded in 2025 to a new brass alloy internal mechanism, adjusting the weight and balance of the barrel and increasing the longevity of the mechanism.
