Genesis G90 Audio Upgrade Review: Enhanced Sound

Genesis G90 Lexicon Audio: A Solid Foundation with Room for More

The Genesis G90 is renowned for its striking design and luxurious interior. The factory Lexicon audio system contributes significantly to this premium experience, offering a rich and dynamic soundstage with its 3-way multi-speaker setup in the doors and a dedicated bass speaker in the rear shelf. However, even sophisticated factory systems may not perfectly align with every owner's specific audio preferences, especially when prioritizing a driver-centric sound environment. While the stock system provides a good baseline, some owners seek greater soundstage accuracy and higher resolution.

Many owners recognize the limitations of their factory audio but are unsure how to proceed with an upgrade. Simply swapping speakers or pursuing ill-advised tuning can lead to disappointment. Therefore, a professional assessment and a customized approach tailored to your driving style and listening habits are crucial for achieving true audio satisfaction.

Elevating the G90's Sound with Premium Components

This Genesis G90 received a significant audio enhancement using key components designed to push the boundaries of its sound capabilities. The upgrade featured the Musway D8 DSP amplifier and Focal PS165 FSE speakers. A Digital Signal Processor (DSP) amplifier is vital for fine-tuning audio, allowing for precise adjustments to maximize each speaker's potential. The Focal speakers were chosen for their ability to deliver a robust sound texture and an engaging listening experience. Complementing these components, premium sound deadening was applied to the front doors to further optimize speaker performance and reduce unwanted noise.

The installation process began with meticulous masking to protect the vehicle's interior and exterior surfaces. This attention to detail ensures a scratch-free and clean installation. The factory Lexicon tweeters and mid-bass speakers in the front doors were carefully replaced, utilizing original connectors where possible to maintain a factory-like integration. Special attention was paid to water-proofing the door cavities to prevent moisture ingress, a critical step for speaker longevity and performance.

Sound deadening and insulation were applied to the door panels to combat vibrations and road noise, contributing to a more refined acoustic environment. The factory Lexicon amplifier, typically located in the trunk, was disconnected. The new Musway D8 DSP amplifier was then integrated using a plug-and-play harness, connecting seamlessly to the vehicle's wiring. Finally, sophisticated measurement equipment was employed for precise DSP tuning. The tuning process established a balanced, flat sound profile as a foundation, with further adjustments made to enhance specific frequencies and align the soundstage with the owner's preferences, ensuring a truly personalized listening experience.

The Critical Role of DSP Tuning

DSP tuning is arguably the most crucial step in any significant car audio upgrade. It goes beyond simply installing new hardware. This process involves analyzing the complex acoustic environment within the car's cabin and meticulously adjusting the timing, equalization, and level of each speaker. The goal is to ensure that sound reaches the listener's ears from each speaker at the optimal moment and with the correct balance, creating a cohesive and immersive soundstage. Without proper DSP tuning, even the most expensive components may not deliver their full potential, and the sound can feel disjointed or unfocused.
