Our Review

Introduction

The RBH Sound 661-SF/R is a notable addition to RBH Sound's Signature SV Reference Series, offering high-fidelity performance for both 2-channel stereo systems and home theater setups. This two-way floorstanding speaker employs a D'Appolito design and features RBH Sound's proprietary AMT (Air Motion Transformer) tweeter, developed in collaboration with Aurum Cantus. With two 6.5-inch reference aluminum midwoofers, this speaker promises accurate and detailed sound reproduction across a wide frequency range. In this review, we will delve into the design, sound performance, compatibility, and overall pros and cons of the RBH Sound 661-SF/R.

Design and Build Quality

The RBH Sound 661-SF/R showcases a sleek and attractive design, with dimensions of 21.5 inches in height, 7.75 inches in width, and 11.63 inches in depth. This compact size allows for easy placement in various listening spaces, making it suitable for both small and large rooms. The speaker weighs 27.25 pounds, providing stability while also being relatively lightweight for convenience.

The RBH Sound 661-SF/R is available in two finishes: black piano lacquer and rosewood. Both options exude a sense of sophistication and will complement different room aesthetics. Additionally, the speaker boasts sturdy construction, featuring a cast aluminum basket and aluminum cone drivers, ensuring durability and longevity. The magnetic grille is not only functional but also adds to the overall elegant design of the speaker, allowing for easy removal and attachment.

Sound Performance

When it comes to sound performance, the RBH Sound 661-SF/R truly impresses. It excels in accurately reproducing instrument timbres and tonality, resulting in a gorgeous and lifelike sound. The proprietary AMT tweeter plays a significant role in achieving this level of accuracy, delivering precise high-frequency reproduction with excellent detail and clarity. The slight warmth in the sound signature adds a touch of richness without compromising transparency or micro-detail retrieval, enhancing the overall listening experience.

Soundstaging is another area where the RBH Sound 661-SF/R truly shines. It offers exceptional spatial rendering, creating a wide and immersive soundstage. The speaker's ability to deliver three-dimensional imaging of performers adds a sense of realism to the listening experience. Additionally, the RBH Sound 661-SF/R seamlessly disappears into the soundstage, allowing the listener to feel a genuine presence and connection with the music.

The speaker's performance extends beyond music to home theater applications. It excels in reproducing crystal-clear dialog and vibrant sound effects, resulting in superb clarity and acoustic performance.

Compatibility and Versatility

While the RBH Sound 661-SF/R offers impressive bass response, it does have limitations in terms of bass extension. The speaker starts rolling off around 50 Hz, which may not satisfy listeners seeking chest-thumping bass or room pressurization. However, RBH Sound has addressed this by designing the speaker to seamlessly integrate with a quality subwoofer. Adding a subwoofer not only extends the bass response but also enhances the overall audio performance, especially for home theater enthusiasts who crave impactful low-end effects.

In terms of setup options, the RBH Sound 661-SF/R is versatile and can be used as both main speakers or effect channels in multi-channel surround sound systems.
