Unveiling the Essence of Acoustic Perfection

Imagine a sound so crisp, so vibrant, and so true to the original recording that it transports you to a different place and time. The RBH Sound 61-SFM from the Signature Series Modular Tower collection is engineered to do just that—bring the live concert experience into the comfort of your home. With a legacy of sound excellence, RBH Sound has meticulously crafted a speaker that stands as a testament to their commitment to audio purity.

The Heart of Your Home Theater

At the core of the 61-SFM lies a trio of expertly designed drive units:

  • Dual 8" Reference Aluminum Cone Woofers: These serve as the powerhouse of the system, delivering robust and controlled bass that fills the room without overpowering the subtleties of the music.
  • A 6-1/2" Aluminum Cone Woofer: Equipped with a solid aluminum phase plug, it bridges the gap between the deep lows and the delicate highs, ensuring a smooth transition and a full-bodied midrange.
  • A Precision AMT Tweeter: Measuring 1.38" x 1", the Air Motion Transformer tweeter provides a sparkling top-end that captures the nuances of each note with incredible clarity.

A Symphony of Specifications

The RBH Sound 61-SFM isn't just a speaker—it's a meticulously tuned instrument designed to resonate with the soul of music. Here's why its specs are music to the ears of audiophiles:

  • Frequency Response: A wide range from 30Hz to 40kHz, ensuring every note is heard just as the artist intended.
  • Sensitivity: At 87 dB, it's efficient enough to be driven by a modest amplifier, yet capable of handling up to 300 Watts for those who demand more power.
  • Impedance: The 6 Ohms rating makes it compatible with a wide range of amplifiers and receivers, offering flexibility in system configuration.
  • Crossover Design: With a crossover frequency set at 100 Hz and 2700 Hz and a slope of 12dB/Octave, it guarantees a seamless integration of frequencies across the different drivers.

The Art of Cabinet Craftsmanship

The RBH Sound 61-SFM isn't just about what's on the inside. Its cabinet is constructed from High Density Fiberboard (HDF), chosen for its acoustic properties and durability. The cabinet is then finished in a choice of black or white satin paint, exuding elegance and sophistication. The magnetic grille, available in matching black or white fabric, adds to the seamless aesthetic while protecting the precious components within.

Dimensions and Build Quality

  • Finished Dimensions: 11-1/4" x 44-9/16" x 12-5/16", the 61-SFM commands presence but does so with an air of understated grace.
  • Weight: At 62 lbs, it's solid enough to remain unfazed by the power it projects, ensuring it remains as a centrepiece in your listening environment for years to come.
  • Warranty: A 10-year limited warranty reflects the confidence RBH Sound has in their craftsmanship and the longevity of their product.

The Sealed Enclosure Advantage

Unlike ported designs, the sealed enclosure of the 61-SFM ensures tight and accurate bass response. This design choice eliminates the possibility of port noise and provides consistent performance across various room placements. It's an audiophile's preference, as it focuses on precision over sheer power.

Aural Delights

Our Review


The RBH Sound 61-SFM is a monitor speaker that aims to deliver high-quality sound reproduction in a compact form factor. With a sealed enclosure design and a focus on smooth and detailed sound, this speaker promises to elevate your audio experience. In this review, we will delve into its design, sound performance, power handling, and more to help you determine if it's the right fit for your home theater setup.

Design and Build Quality

The RBH Sound 61-SFM features a sealed enclosure design without a rear port. This design choice provides several advantages, including improved transient response, reduced room interaction, and greater placement flexibility. The overall construction of the speaker is top-notch, with RBH Sound using quality materials that contribute to its durability and aesthetic appeal. The sleek design and attention to detail make the RBH Sound 61-SFM an attractive addition to any home theater system.

Sound Performance

At the heart of the RBH Sound 61-SFM are its silk dome tweeter and in-house aluminum woofer. This combination allows for accurate sound reproduction across the frequency spectrum. The speaker is also capable of playing decently low frequencies, ensuring that you can enjoy a full-bodied audio experience without the need for additional subwoofers.

One of the standout features of the RBH Sound 61-SFM is its ability to deliver smooth and detailed sound. Whether you're listening to music or watching movies, the speaker excels at reproducing intricate details and nuances in the audio. Instruments and vocals sound natural, with accurate highs and mids that add depth and realism to the soundstage.

Speaking of the soundstage, the RBH Sound 61-SFM offers an open and spacious soundstage with good width on most recordings. It creates a sense of immersion, allowing you to feel like you're in the middle of the action. However, there are limitations to the soundstaging depth, especially on certain recordings. While the speaker does a commendable job in most scenarios, it may feel slightly closed-in and boxy on some tracks.

Power Handling and Amplification

The RBH Sound 61-SFM is designed to handle power well, allowing you to crank up the volume without distortion or compromise in sound quality. However, it truly shines when paired with quality amplification. Investing in a high-quality amplifier will unlock the full potential of the speaker, enhancing its performance and delivering a more refined audio experience.

For two-channel listening, some users may find that the RBH Sound 61-SFM benefits from the addition of a subwoofer. While the speaker is capable of reproducing low frequencies, the inclusion of a subwoofer can further enhance the bass response and provide a more immersive experience. This is especially relevant for those who enjoy deep, impactful bass in their audio setup.


The RBH Sound 61-SFM has several strengths that make it a compelling choice for discerning audio enthusiasts. One of its standout features is the smooth and detailed soundstage it delivers. The speaker excels at sound separation, richness, and depth, ensuring that each instrument and vocal is clearly defined and placed within the audio mix.

The RBH Sound 61-SFM also impresses with its ability to reproduce natural tones on instruments and vocals. The timbre accuracy adds a layer of authenticity to the audio, allowing you to truly appreciate the nuances in your favorite tracks. Users have reported positive feedback, particularly in acoustic jazz recordings, where the speaker's performance shines.

Furthermore, the RBH Sound 61-SFM is not only a performer but also a stunner in terms of design. Its well-constructed and aesthetically pleasing design makes it a visually appealing addition to any home theater setup. The attention to detail and quality materials used in its construction ensure that it not only sounds great but also looks great.


While the RBH Sound 61-SFM offers an impressive audio experience, there are some areas where it falls short compared to more expensive speakers. One notable limitation is the loss of high-frequency extension and definition. While the speaker performs admirably in most scenarios, it may lack the same level of clarity and detail as some higher-end options.

Another aspect to consider is the soundstaging depth. While the RBH Sound 61-SFM provides an open and spacious soundstage on most recordings, there are instances where it may feel slightly limited. This can be a drawback for audiophiles seeking an expansive and immersive soundstage experience.

In terms of sound quality, some users have noted that the RBH Sound 61-SFM can sound slightly closed-in and boxy. While this is not a significant issue for most listeners, it's worth considering if you prefer a more open and airy sound signature.

Lastly, the RBH Sound 61-SFM benefits from decent quality power to truly shine. While it handles power well, a high-quality amplifier can elevate its performance even further. Additionally, for two-channel listening, some users may find that the addition of a subwoofer enhances the overall audio experience, particularly for those who crave deep bass.


The RBH Sound 61-SFM monitor speaker offers a compelling combination of smooth and detailed sound reproduction, aesthetic appeal, and solid construction. Its ability to handle power well and deliver a natural sound on instruments and vocals makes it a worthy contender in its price range. However, it's important to consider its limitations, such as the slight loss of high-frequency extension and depth in soundstaging.

Overall, the RBH Sound 61-SFM is a solid choice for those who prioritize smooth and detailed sound reproduction. With its well-constructed design and natural sound reproduction, it can elevate your audio experience and bring your favorite music and movies to life. Just ensure you have decent quality power and consider adding a subwoofer for a more comprehensive two-channel listening experience.
