VIP Completions recently installed an Alto Aviation cabin audio system in a Gulfstream IV-SP as part of a complete aircraft refurbishment that also included new wood, upholstery, carpeting, soft goods, plating, lighting, and video upgrades. The Alto system replaced an obsolete factory-installed audio system.

The Alto equipment features six ultralight, high-performance ASP-401 mid-high loudspeakers that were fit-compatible replacements for the original loudspeakers. It also includes the placement of four ASW-279 Alto subwoofers into the aircraft's two cabin zones, as well as installation of two Alto DA-230 amplifiers.

An Alto cabin systems engineer tuned the system on site at the VIP Completions facility in Fort Lauderdale, Florida, to match the aircraft's acoustic profile upon completion of the installation. "The aircraft came with its original interior," said VIP Completions president Ben Shirazy. "At almost 20 years old, it was dated visually and [from a] cabin entertainment and connectivity standpoint. The owner wanted to modernize everything and insisted on the best of the best.”
