Its \"Ring Lock\" concept aims for a tight and stable fit, particularly useful when seeking a clean installation with minimal vibrations and quick assembly\/disassembly.\u003c\/p\u003e\u003ch3\u003eFor whom and for what: sound reinforcement, monitors, compact installations\u003c\/h3\u003e\u003cp\u003eThis tube is intended for \u003cstrong\u003esound reinforcement\u003c\/strong\u003e users who want to install a speaker above a subwoofer while maintaining a reduced height. It is suitable for both mobile setups (performances, DJs, events) and fixed installations requiring a reliable connection between the speaker and the support, with an appropriate load capacity.\u003c\/p\u003e\u003ch3\u003eStability, tightening, and ease of use\u003c\/h3\u003e\u003ch4\u003e\"Ring Lock\" expansion mandrel: firm and play-free hold\u003c\/h4\u003e\u003cp\u003eThe upper part integrates a unique and patented expansion mandrel designed to achieve a tight fit of the speaker on the tip.
