ALTO Aviation, a supplier of customized cabin audio and cabin management systems for Business Aviation, has partnered with VIP Completions, providers of business aircraft completions and refurbishment service, for the recent installation of a new ALTO cabin audio system in a Gulfstream GIV SP aircraft. This installation is part of a complete aircraft refurbishment that included 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 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 in Ft. 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 optimized 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 and cabin entertainment and connectivity standpoint. The owner wanted to modernize everything and insisted on the best of the best. We did not hesitate one second in recommending the ALTO product to ensure an incredible audio experience for the owner and all their guests," said Ben Shirazy, President of VIP Completions."Every detail of this seamless installation by VIP Completions is simply outstanding and look straight from the factory; we are so excited and thankful knowing that the ALTO Sound specifically designed for this project has exceeded their client's strict audiophile requirements. We look forward to continuing our valued and consistent partnership with VIP Completions to provide their clients with unrivaled cabin sound quality and to continue exceeding their highest acoustic expectations," said Don Hamilton, ALTO Aviation President.
