OSA Expands Nation’s Largest Martin Audio MLA Inventory

OSA International, Inc. has purchased additional MLA enclosures, expanding the nation’s largest inventory of Martin Audio’s award-winning loudspeaker line.

OSA International, Inc. of Chicago, Las Vegas and Nashville recently purchased additional MLA enclosures to increase what is already the nation’s largest inventory of Martin Audio’s award-winning loudspeaker line.

Celebrating its 30th anniversary of top-quality live production work for tours, corporate shows, product launches, TV broadcasts and special events, OSA just added 26 MLA and 18 MLA Compact enclosures to its already full line inventory.

Because of MLA’s consistent front to back audience coverage, exceptional clarity and noise overspill control, OSA recently used the system for two Steely Dan national tours, the Firefly Music Festival, IFC Stage at SXSW, NBC’s Premier Boxing Champions, The Pavilion at Ravinia, the David Foster Foundation Miracle Gala and Concert, The Broadway League featuring Gloria Estefan and other corporate and special events.

Commenting on the recent purchase, OSA Vice President Jim Risgin said, “Martin Audio’s MLA continues to be a runaway success, making us busier than ever in our 30th Anniversary year. We continue to add inventory to service our locations and other MLA partners as demand for these boxes continues to increase, which is a testament to Martin Audio’s breakthrough technology and engineering team that keeps the system one step ahead of the competition.

“We’ve seen other box manufacturers say they offer optimization and steering, but there’s still nothing on the market that comes close to the feature set of MLA, nor delivers it as successfully and consistently as MLA. Martin Audio continues to improve with every update, using its years of real life experience. Once our customers have tried MLA, they don’t want to use anything else and that’s a big reason why we continue to be successful.”
