M+ Equipment\u00a0delivers concert-grade professional sound system for Grenoble’s modular venue within a venue<\/em><\/p>\n\n\n\n

\n\n\n\n

GRENOBLE, France – June 2025<\/strong>\u00a0– When\u00a0Alpexpo\u00a0recognised that event organisers needed something between Grenoble\u2019s massive arena\u2019s and intimate live venue, \u2014they didn’t just renovate. They revolutionised. The result: an ingenious ‘box in a box’ concept that carves out a state-of-the-art 3389 square meter auditorium within their existing Greater Hall, powered by an L-Acoustics L Series professional sound system.<\/a><\/p>\n\n\n\n

This architectural feat transforms what was once a traditional exhibition space into a chameleon-like venue that adapts seamlessly between intimate seated concerts for 1,495 and energetic standing shows for 2,100. The real magic happens in the transitions\u2014where comedy shows morph into corporate presentations, where business conventions become live concert halls, and where every configuration delivers an unforgettable sonic experience.<\/p>\n\n\n\n

Engineering Versatility<\/strong><\/p>\n\n\n\n

“Our challenge was creating an adaptable system that could be everything to everyone \u2013 pristine audio whether hosting a morning keynote or an evening concert \u2013 and the transformation had to be instant,” recalls Antoine Maurel, Sales & Installation manager at L-Acoustics Certified Partner M+ Equipment, part of M Group. “They wanted to build a complete auditorium inside their existing hall\u201d<\/p>\n\n\n\n

The challenge went beyond mere logistics. For over five decades, Alpexpo\u2014a venue with Olympic heritage dating to 1968\u2014has served as the Alps region’s premier event destination. But evolving audience expectations and a growing demand for venues that could handle everything from stand-up comedy to hybrid and immersive multimedia experiences, the traditional approach no longer sufficed.<\/p>\n\n\n\n

Engineering the Sound Solution<\/strong><\/p>\n\n\n\n

\u201cWith the existing attachment points, we needed to have a lightweight and efficient system adapted to the type of events, hence the L2<\/a>,\u201d Maurel adds.<\/p>\n\n\n\n

The answer came through the exceptional weight-to-power ratio of the L Series meaning the team could deploy a full concert-grade line array system: two L2D<\/a> arrays as the main system, complemented by three flown KS21<\/a> subwoofers per side in cardioid configuration for controlled low-frequency management. A centre cluster featuring A10 Wide<\/a> and A10 Focus<\/a> speakers ensures perfect coverage for the first audience rows.<\/p>\n\n\n\n

“The L Series gave us something we couldn’t achieve before,” Antoine Maurel explains. “Through advanced DSP processing, we can completely transform the acoustic environment. No manual intervention, no compromise on quality\u2014just instant adaptation to whatever the event demands.”<\/p>\n\n\n\n

The installation includes sophisticated monitoring solutions with permanently hung A10 speakers and mobile X8<\/a> units, plus six additional X8 speakers for stage lip coverage when needed. Every element was meticulously modeled using Soundvision software, giving stakeholders\u2014including venue management, structural engineers, and government consultants\u2014complete confidence in the coverage and performance.<\/p>\n\n\n\n

Racing Against Time<\/strong><\/p>\n\n\n\n

Perhaps most remarkably, the entire project\u2014from initial concept to opening night\u2014was completed in just a few months. This rapid execution required unprecedented coordination between all parties, with M+ Equipment working alongside Alpexpo’s team to ensure every deadline was met without compromising quality.<\/p>\n\n\n\n

“L-Acoustics systems are installed throughout our region, and their reputation for excellence made them our natural choice,” notes J\u00e9r\u00f4me Riff, Managing Director of Alpexpo. “But what truly impressed us was how this solution goes beyond sound. It’s enabled us to reimagine what our venue can be\u2014from hosting agricultural conferences in the morning to world-class performances that evening, creating memorable experiences. This flexibility doesn’t just serve our business needs; it enriches our entire community’s cultural life.”<\/p>\n\n\n\n

A New Chapter Begins<\/strong><\/p>\n\n\n\n

By creating a sophisticated performance space within an existing structure, the\u00a0Alpexpo\u00a0team has not only solved their own challenge but provided a blueprint for other venues facing similar constraints. “It’s not just a professional sound system; it’s a complete ecosystem that reflects our venue’s ability to adapt and excel,” concludes Riff. “We’ve created something truly unique for the Grenoble region\u2014a space that can be whatever our community needs it to be.”<\/p>\n\n\n\n
