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

Each pair of these staggering 92-inch (3.86m) tall, ultimate modular towers presents a full range sonic experience that is truly unrivaled by other tower systems at any price. Dressed in a spectacular eight-layer polyester high-gloss piano black finish, each SVTRS-AX speaker system is comprised of four 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 7500 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.



The RBH Sound UNRIVALED SVTRS/AX is a limited edition active SVTRS (Signature Reference Theater Reference System) system that pushes the boundaries of home theater audio. With only 20 pairs available, this system offers exclusivity alongside cutting-edge technology and impeccable craftsmanship. In this review, we will delve into the design, performance, and overall experience of this exceptional home theater system.

Design and Build Quality

The RBH Sound UNRIVALED SVTRS/AX system boasts a modular design, consisting of three stacked boxes per left and right speaker. This modular approach not only facilitates easier setup and transportation but also contributes to the overall aesthetics of the system. Each SVTRS speaker weighs over 300 lbs and stands an impressive 7.5 ft tall, making a bold statement in any home theater space.

The construction of the SVTRS speakers is top-notch, utilizing high-quality materials to ensure durability and resonance-free sound reproduction. The magnetic grille covers, made of chamfered HDF (High-Density Fiberboard), not only provide an elegant and secure fit but also contribute to the rigidity of the system. The attention to detail in the design and build quality of the RBH Sound UNRIVALED SVTRS/AX system is truly commendable.

Technology and Performance

RBH Sound's UNRIVALED SVTRS/AX system incorporates their proprietary FAST (Focal-point Active Speaker Technology) with trickle-down technology from their UNRIVALED line. The inclusion of SOTA (State-of-the-Art) DSP (Digital Signal Processing) processing from Marani ensures precise active filters, FIR (Finite Impulse Response) correction, and bass management. This advanced technology optimizes the performance of the drivers and enhances the overall audio quality.

The Class D amplification, designed by RBH Sound, delivers efficient power to the speakers while maintaining a consistent frequency response. This amplification technology not only ensures accurate reproduction of audio signals but also contributes to the overall efficiency of the system. The RBH Sound UNRIVALED SVTRS/AX system stands out in terms of technological innovation and performance.

Audio Quality

The RBH Sound UNRIVALED SVTRS/AX system excels in delivering outstanding audio quality. The dual SV-1212 subwoofers provide powerful and controlled bass output, immersing the listener in a rich and dynamic low-frequency experience. The integration of these subwoofers with the three 8" mid-bass drivers results in a seamless transition between the low and mid frequencies, creating a cohesive and engaging soundstage.

The presence of a large 4.7"x1" Aurum Cantus AMT (Air Motion Transformer) tweeter adds a touch of finesse to the high-frequency reproduction. This tweeter technology ensures exceptional clarity and detail in the upper frequencies, enhancing the overall audio experience. The RBH Sound UNRIVALED SVTRS/AX system delivers a balanced and immersive soundstage, making it an ideal choice for both movie enthusiasts and audiophiles.

Amplification Options

The RBH Sound UNRIVALED SVTRS/AX system offers two models to choose from: the UNRIVALED UA-8 and UA-6. The UA-8 model provides eight channels of amplification, while the UA-6 model offers six channels. The choice between these models depends on the specific requirements of your home theater setup.

Both models deliver high-quality amplification, ensuring consistent performance across the frequency spectrum. The amplification technology used in these models maintains efficiency and precision, allowing the SVTRS speakers to shine in their full glory. RBH Sound has spared no expense in providing amplification options that complement the exceptional performance of the UNRIVALED SVTRS/AX system.

Ease of Setup and Use

Setting up the RBH Sound UNRIVALED SVTRS/AX system may require some expertise due to its complexity and the need for precise wiring. It is advisable to seek professional assistance during the setup process to ensure optimal performance and avoid any potential issues. However, the modular design of the system simplifies the setup and transportation compared to traditional floor-standing speakers.

Once set up, the RBH Sound UNRIVALED SVTRS/AX system is user-friendly and straightforward to use. The system integrates seamlessly with home theater receivers and processors, allowing for effortless control and customization. RBH Sound has struck a balance between advanced technology and user-friendliness, ensuring that even enthusiasts with limited technical knowledge can fully enjoy this exceptional home theater system.

Availability and Pricing

The RBH Sound UNRIVALED SVTRS/AX system is a limited edition offering, with only 20 pairs available. This exclusivity adds to the allure of the system, making it a coveted choice among home theater enthusiasts. However, the limited production and availability may make it challenging to purchase, especially for those who are not quick to secure their order.

This premium pricing may deter some potential buyers who are seeking a more budget-friendly option. However, for those who can afford it, the RBH Sound UNRIVALED SVTRS/AX system delivers an unparalleled home theater experience that justifies its cost.
