Royal Global 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. 

Upgraded in 2024 to a new brass alloy internal mechanism, the 2024 Polaris adjustable barrel is approximately 34 grams heavier than the previous version, contributing to a denser sound with greater projection.

Manufactured from premium naturally aged grenadilla (African blackwood) and a new Royal Global exclusive material, the Royal Global adjustable barrels are unlike anything else on the market. Patented technology with a unique internal design allows the clarinetist to adjust pitch with a center ring mechanism.

Four indicators milled on the ring allow for easily repeatable adjustments, with marks every .25mm. That means one full turn of the ring will lengthen or shorten the barrel by one full millimeter.  By turning the ring instead of pulling out from the tenon, the barrel socket maintains contact with the upper joint. It greatly reduces the gap diameter caused by pulling out a regular barrel, allowing for a more resonant, connected sound and reducing the possibility of leaking when adjusting.

The length is adjustable from 64mm to 68mm and works for both Bb and A clarinets with "standard" size tenons (Royal Global, Buffet, Selmer Paris, Yamaha, Backun, etc.)

Bore

The Polaris Adjustable Barrel bore employs an inverted taper that helps to improve intonation, especially between the twelfths, as well as response and overall "focus" of the sound. There is a good balance of highs and lows, not too "dark" or "bright," but of course this is subjective depending on the player and their set-up. 

Plating

The Polaris Adjustable barrel is available in 4 different platings. Although we believe the bore dimensions, material, and overall mass of the barrel play a larger role in the sound, many people believe that the plating does have an impact on the sound. We suggest choosing the plating that speaks to your preferred aesthetic, or purchasing multiple for a trial and returning the other barrels within 7 days of delivery per our trial policy.

Warranty

All barrels hold a 1 year warranty against manufacturer defect, including cracking not caused by user care.
