We're proud to be an authorized dealer of RBH Sound

Each pair of these 62-inch (1.5m) tall, ultimate modular towers presents a full range sonic experience that is truly unprecedented for its size. Dressed in a spectacular eight-layer polyester high-gloss piano black finish, each SVTR-AX speaker system is comprised of two SV-1212NR subwoofers and two SV-831R modules that are integrated together with a Linear Phase FIR filter processor which time aligns the drivers and linearizes the frequency response of the speaker system to within an unprecedented ±1dB. The large air motion transformer (AMT) tweeter integrates perfectly with the proprietary aluminum-cone mid-bass woofers which are arranged in an alignment we call a “dispersion averaging alignment.” This driver alignment reduces the typical lobing interference between separate drivers producing the same frequencies and provides more focused imaging throughout the soundstage. Amplification for the speakers is handled by RBH Unrivaled amplifiers which provide 250 Watts per channel for the AMT tweeters, 500 Watts per channel for the 8-inch woofers, and 1,500 Watts per channel for each of the dual 12-inch long throw subwoofers. Yes, that is 4500 Watts of total available power! A customized digital signal processor provides active crossover management with linear phase filters for optimal time alignment at the listening position. The SVTRS Limited Edition is so detailed, so controlled, and so sonically accurate that it will simply leave you in awe. Each system is set up and calibrated on-site by an RBH Sound team member to ensure your experience is nothing but perfect.



RBH Sound is a well-known manufacturer in the audio industry, and their UNRIVALED SVTR/AX tower system is a testament to their commitment to delivering high-quality sound. With both active and passive configurations available, this speaker system offers versatility to suit different setups and preferences. Priced at $15,900 for the passive configuration, the UNRIVALED SVTR/AX is positioned as a premium option for audiophiles seeking exceptional sound reproduction. Let's delve into the details of this impressive tower system.

Design and Construction

The RBH Sound UNRIVALED SVTR/AX features a unique speaker design, with two separate RBH speakers connected by a special plate. This design aims to enhance the overall soundstage and instrument placement, providing a captivating listening experience. The cabinet construction is of high quality, with one-and-a-half-inch thick front baffles and one-inch walls. This construction not only ensures sturdiness but also minimizes resonances, resulting in cleaner sound reproduction.

The UNRIVALED SVTR/AX is available in two attractive finish options: high gloss black or high gloss South American Rosewood. The choice of finish allows users to seamlessly integrate these speakers into their existing home decor. The inclusion of old school grilles made of black cloth wrapped around a wood frame adds a touch of classic elegance to the overall design.

Performance and Sound Quality

One of the standout features of the RBH Sound UNRIVALED SVTR/AX is its ability to create an immersive soundstage with precise instrument placement. The speakers excel in reproducing drums and instruments, delivering clear and impactful sound that truly brings music to life. The three eight-inch midranges and large AMT tweeter work in harmony to provide detailed and accurate highs, while the two twelve-inch woofers deliver deep and controlled bass.

With a sensitivity rating of 93 dB and high power handling capacity, the UNRIVALED SVTR/AX can handle demanding audio passages with ease. Whether you're watching movies or listening to multi-channel music, these speakers excel at creating a dynamic and engaging listening experience. Additionally, the ability to fine-tune and customize the sound for different rooms ensures optimal performance in any environment.

In the active configuration, the UNRIVALED SVTR/AX speakers offer a disappearing effect and precise imaging, further enhancing the overall listening experience. The active configuration utilizes the Marani DPA-2448DSP processor, which allows for greater control and optimization of the sound. However, it's worth noting that while the active configuration performs admirably, it may not match the nuanced detail of some high-end speakers in a similar price range.

Even at high volumes, the UNRIVALED SVTR/AX maintains its composure, delivering deep and detailed bass without any loss of clarity or distortion. This is a testament to the quality of the drivers and the cabinet construction, which work in tandem to provide a well-balanced and controlled audio experience.

User Experience

As impressive as the RBH Sound UNRIVALED SVTR/AX is in terms of performance, there are some considerations to keep in mind when it comes to the user experience. Firstly, due to their large size and weight (205 pounds per side), setting up these speakers may require assistance. It's important to ensure that you have the necessary help or equipment to safely position them in your listening space.

In terms of aesthetics, the UNRIVALED SVTR/AX speakers adopt a more traditional and blocky design. While this may not appeal to those seeking a more modern and sleek look, it's worth noting that the focus of these speakers is on performance rather than aesthetics.

The electronics of the UNRIVALED SVTR/AX, particularly the Marani DPA-2448DSP processor, could benefit from some refinement. The user interface may not be as intuitive or user-friendly as some other options on the market. Additionally, the manual power switch located on the back of the processor may be inconvenient for those who prefer easily accessible controls. Furthermore, the brightness of the display on the Marani processor cannot be dimmed, which may be a minor annoyance for those who prefer a darker listening environment.

Configuring and setting up the UNRIVALED SVTR/AX can be a complex process, especially for users who are not familiar with advanced audio systems. It's advisable to carefully follow the provided instructions or seek assistance to ensure optimal performance and avoid any potential issues.

Build Quality and Customer Support

RBH Sound has always been known for their commitment to quality, and the UNRIVALED SVTR/AX is no exception. The cabinet construction is solid, with high-quality wood and thick front baffles, ensuring durability and minimizing resonances. The available finish options, whether it be the high gloss black or the high gloss South American Rosewood, add a touch of elegance to these already impressive speakers.

In terms of customer support, RBH Sound has a reputation for being responsive and attentive. Should any issues arise, their team is readily available to assist and provide solutions, which is reassuring for potential buyers.

Comparison and Value

When considering the RBH Sound UNRIVALED SVTR/AX, it's important to note that direct comparisons with other speaker systems are limited. However, based on its specifications and performance, it can be seen as a strong contender in the premium speaker market. While the price point of $15,900 for the passive configuration may be higher than some competitors, it is reflective of the exceptional sound quality and craftsmanship that RBH Sound brings to the table.


The RBH Sound UNRIVALED SVTR/AX is a true full-range tower system that offers impressive soundstage and instrument placement. With its clear and impactful reproduction of drums and instruments, high sensitivity, and power handling capacity, it excels in delivering a captivating audio experience. The ability to fine-tune and customize the sound, as well as the deep and detailed bass performance, further enhance its appeal.

While the setup process may require assistance due to the size and weight of the speakers, and the aesthetics and user interface could benefit from refinement, these are minor drawbacks when considering the overall performance and build quality. RBH Sound's responsive customer service is an added bonus, ensuring a positive ownership experience.

With its premium price point, the RBH Sound UNRIVALED SVTR/AX may not be for everyone. However, for those seeking uncompromising sound quality and a truly immersive listening experience, it represents a solid investment.
