Introduction

The RBH Sound Reference 643-I is a high-end in-wall speaker that promises to deliver exceptional audio performance and seamlessly integrate into any home theater setup. This speaker is part of the Signature Reference In-wall models by RBH Sound, known for their commitment to quality and innovation in the audio industry. With a suggested retail price of $3,309 per unit, the Reference 643-I is positioned as a premium offering for discerning audio enthusiasts.

Design and Build Quality

The Reference 643-I features a sleek and minimalistic design that blends seamlessly into any room decor. Its in-wall design allows for a discreet installation, eliminating the need for bulky floor-standing speakers that can take up valuable space. The visible parts after installation are the baffle and the optional black/off-white grill, giving users the flexibility to choose the aesthetic that best suits their preferences. RBH Sound has always been known for their high-quality construction, and the Reference 643-I is no exception. Incorporating upgraded, high-performance proprietary 6.5-inch aluminum cone woofers, this speaker is built to last. The fixed-phase plug in the woofers reduces acoustic 'beaming' and increases power handling, ensuring that the speaker can handle demanding audio playback without distortion or strain.

Performance

When it comes to audio performance, the RBH Sound Reference 643-I aims to deliver beyond expectations. Borrowing high-quality drivers from RBH Sound's sister company, Status Acoustics, this speaker is equipped to handle high power levels of up to 500 Watts. This power handling capability ensures that the Reference 643-I can reproduce sound accurately and with authority, even at high volume levels. The Reference 643-I boasts a comprehensive frequency response of 45Hz-20kHz ±3dB, allowing for accurate sound reproduction across a wide range of frequencies. This wide frequency response ensures that listeners can enjoy the full spectrum of sound, from deep and powerful bass to crystal-clear highs. One notable feature of the Reference 643-I is its potential for wide horizontal dispersion. The wide horizontal dispersion mentioned in the product details can be advantageous for creating a spacious soundstage, allowing listeners to experience a more immersive audio experience. This feature is particularly beneficial for larger rooms or setups where a wide soundstage is desired. However, it's worth noting that the Reference 643-I has a narrow vertical dispersion. This means that the optimal listening position may be limited, and listeners may need to be positioned at ear level to fully experience the speaker's performance. This aspect may require careful consideration when planning the installation and positioning of the speaker within a room.

Installation and Convenience

RBH Sound understands the importance of convenience when it comes to speaker installation. The Reference 643-I comes with its own backbox, which not only enhances sonic performance but also simplifies the installation process. The backbox helps to isolate the speaker from the wall, reducing unwanted vibrations and resonance that can affect the overall sound quality. Additionally, the inclusion of the backbox ensures that the Reference 643-I can be easily integrated into any home theater setup. Setting up the Reference 643-I is a straightforward process that can be completed by both DIY enthusiasts and professional installers alike. RBH Sound provides clear instructions and all the necessary mounting hardware, ensuring a hassle-free installation experience.
