The RBH Sound 661C-SF/R is a part of RBH Sound's Signature SV Reference Series, known for its high-performance and exceptional audio quality. This two-way D'Appolito design speaker features a proprietary AMT tweeter developed in collaboration with Aurum Cantus, along with two 6.5-inch reference aluminum midwoofers. With a frequency range of 50 Hz to 40 KHz and a sensitivity of 90 dB, the RBH Sound 661C-SF/R promises to deliver accurate and immersive sound reproduction. Let's dive into the design, performance, and limitations of this speaker to determine if it lives up to its claims.

Design and Build Quality

The RBH Sound 661C-SF/R showcases the elegant and refined design that RBH Sound's Signature SV Reference Series is known for. It is available in two attractive finish options: high-quality black piano lacquer or rosewood. The speaker's dimensions of 21.5 inches high by 7.75 inches wide by 11.63 inches deep make it a suitable choice for medium-sized rooms.

The speaker incorporates a classic MTM (midwoofer-tweeter-midwoofer) arrangement, which ensures precise soundstaging and accurate bass reproduction. The proprietary AMT tweeter, a result of collaboration with Aurum Cantus, is a standout feature of the RBH Sound 661C-SF/R. This innovative tweeter is known for its high-performance and seamless integration, promising to deliver exceptional clarity and detail in the high-frequency range.

The RBH Sound 661C-SF/R also features high-quality speaker wire terminals and dual ports on the back, allowing for easy connectivity and adjustment to optimize the speaker's performance in any room.

Performance and Sound Quality

One of the standout qualities of the RBH Sound 661C-SF/R is its ability to deliver accurate tonality and timbre reproduction. Music enthusiasts will appreciate the speaker's ability to faithfully reproduce the instrument's natural sound, ensuring an enjoyable and immersive listening experience. The slight warmth in the sound signature adds a touch of musicality without compromising transparency or micro-detail retrieval.

The RBH Sound 661C-SF/R creates a realistic soundstage, offering three-dimensional imaging that enhances the listener's perception of space and instrument placement. Whether you're listening to a live recording or a studio production, this speaker excels at capturing the essence of the recording, allowing you to feel like you're in the presence of the performers.

One of the most impressive aspects of the RBH Sound 661C-SF/R is its ability to disappear into the background, creating a truly immersive listening experience. The speaker's ability to blend seamlessly with the room and the music allows the focus to be on the music itself rather than the speakers, offering an undistracted and engaging experience.

Amplifier Compatibility and Integration

The RBH Sound 661C-SF/R is designed for easy integration with both solid-state and tube amplifiers. This versatility makes it suitable for a wide range of users with different amplifier preferences. Whether you prefer the clean and precise sound of solid-state amplification or the warm and euphonic sound of tube amplifiers, the RBH Sound 661C-SF/R will deliver exceptional performance.

Additionally, this speaker is suitable for lovers of jazz, acoustic, classical, opera, and vocal-centric music genres. Its ability to faithfully reproduce nuanced and delicate performances makes it an excellent choice for those who appreciate the subtleties and dynamics of these genres. However, it may not be the ideal choice for rock, electronic, or rap music enthusiasts who crave heavy bass impact and high dynamics at very high dB levels.

Limitations and Considerations

While the RBH Sound 661C-SF/R offers impressive sound quality, there are a few limitations to consider. The bass extension rolls off at around 50 Hz, which may not satisfy deep bass enthusiasts. If you're someone who enjoys music with heavy bass presence, considering a subwoofer to complement the RBH Sound 661C-SF/R would be advisable.

Furthermore, at very high dB levels, the RBH Sound 661C-SF/R may lack overall punch and dynamics. If you regularly listen to music at extremely high volume levels or enjoy genres that demand exceptional dynamic range, you may want to explore larger floorstanding models within the Signature SV Series, as they offer more dynamics and deeper bass response.


In conclusion, the RBH Sound 661C-SF/R from the Signature SV Reference Series is a remarkable performer that delivers accurate tonality, immersive soundstaging, and a seamless integration with the listening environment. Its elegant design and high-quality finishes make it a visually appealing addition to any home theater or music system.

While it may not satisfy deep bass enthusiasts or those seeking extreme dynamics at very high volume levels, the RBH Sound 661C-SF/R excels in providing an enjoyable and immersive listening experience for lovers of jazz, acoustic, classical, opera, and vocal-centric music. Its ability to faithfully reproduce music with accurate tonality and instrument placement ensures that the focus remains on the music itself, allowing you to truly connect with your favorite recordings.

Considering your music preferences and room size, the RBH Sound 661C-SF/R is a highly recommended option for those seeking a refined and immersive listening experience. Its value and performance make it a strong contender in its price range, and it will undoubtedly satisfy discerning audiophiles looking for a speaker that prioritizes accuracy and musicality.
