Customised cabin audio and cabin management systems supplier Alto Aviation has installed a new Alto cabin audio system in a Gulfstream GIV SP aircraft for VIP Completions. This installation is part of a complete aircraft refurbishment that includes new wood, upholstery, carpeting, soft goods, plating, lighting and audio and video upgrades.

The new Alto Sound system replaced the obsolete factory-installed audio system. The installation included six ultralight, high-performance ASP-401 mid-high loudspeakers, which are fit-compatible replacements for the original loudspeakers.

This cabin audio upgrade required a substantial improvement of the bass performance over the original system, which was achieved by strategically placing four ASW-279 Alto subwoofers into the aircraft's two cabin zones, providing a crystal clear, powerful and balanced acoustic performance. In addition, the installation offered excellent sound performance throughout the cabin, fully supported by two Alto DA-230 amplifiers.

An Alto cabin systems engineer tuned the system onsite at the VIP Completions facility at Fort Lauderdale/Hollywood International airport in Fort Lauderdale, Florida, to perfectly match the aircraft's acoustic profile upon completing the installation. Following the specifications of the aircraft owner, the tuning focused on a fully optimised and powerful stereo presentation, with special sonic attention and sweet spots specifically directed to the second row of VIP seats in the forward zone.

"The aircraft came with its original interior; at almost 20 years old it was dated visually as well as from a cabin entertainment and connectivity standpoint," says VIP Completions president Ben Shirazy. "The owner wanted to modernise everything and insisted on the best of the best. We did not hesitate for a second in recommending the Alto product to ensure an incredible audio experience for the owner and all their guests."

"Every detail of this seamless installation is simply outstanding and looks straight from the factory; we are so excited and thankful knowing that the Alto Sound specifically designed for this project has exceeded its client's strict audiophile requirements," adds Alto president Don Hamilton. "We look forward to continuing our valued and consistent partnership with VIP Completions to provide its clients with unrivalled cabin sound quality and to continue exceeding its highest acoustic expectations."
