Description

Description

High-Output Sealed Subwoofer Architecture
The SB17-Ultra R|Evolution is engineered as a sealed, front-firing 17-inch high-excursion subwoofer that delivers reference-grade low-frequency performance in a compact, acoustically inert enclosure. Its robust MDF cabinet with extensive internal bracing, protective non-resonant ABS grille, and screw-in Iso-elastomer feet work together to suppress resonance, minimize mechanical noise, and maintain cabinet stability at the highest drive levels for precise bass reproduction in demanding home theater and audiophile environments.


Advanced 17-Inch Driver and Motor System
At the core of the SB17-Ultra R|Evolution is a proprietary 17-inch long-throw driver featuring a lightweight yet rigid glass fiber composite cone optimized for stiffness-to-mass ratio to ensure efficient, linear pistonic motion. A 63.76 lb woofer assembly, anchored by a four-piece Y35 ferrite magnet motor and precision-machined low-carbon 1010 steel top plate and T-yoke, delivers massive on-demand force, while dual shorting rings, dual Nomex spiders, and an extreme-excursion catenary SBR rubber surround maintain low distortion, controlled excursion, and pinpoint accuracy at reference listening levels.


Revolutionary Dual 8-Inch Voice Coil Topology
The subwoofer employs an unprecedented dual 8-inch voice coil design with 4-layer bifilar copper-clad aluminum windings to maximize thermal efficiency and power handling. This topology ensures highly stable current transfer from the amplifier to the motor structure, enabling effortless acoustic output, extended linear excursion (48.9 mm Xmax, 81.78 mm Xmech), and tight driver control even under extreme operating conditions, resulting in bass that is both dynamically impactful and tonally accurate.


Dual-Mono STA-2800D Amplification and Power Management
Driving the transducer is the STA-2800D amplifier, a massively powerful dual-mono Class D design utilizing discrete MOSFET output stages to deliver immense current reserves with high efficiency and low EMI. A sophisticated switch mode power supply with two-stage active Power Factor Correction, integrated AC line conditioning, and tightly regulated 160 volts rail voltage ensures consistent peak performance, stable operation across a wide range of mains conditions, reduced heat, and reliable delivery of rated power in real-world installations.


295 MHz DSP and Intelligent System Protection
A 295 MHz Analog Devices DSP with double-precision 56-bit filtering orchestrates all signal processing, providing precise in-room response shaping from 15 Hz to 320 Hz (±3 dB), advanced digital audio processing, and DACs with 120 dB signal-to-noise ratio for ultra-low noise and high headroom. Continuous monitoring of thermal, voltage, and current conditions enables complex power management algorithms and DSP limiter behavior tailored to the 17-Ultra platform, safeguarding the driver and amplifier while maintaining maximum dynamic output and consistent low-frequency fidelity.


Integrated App Control
The SB17-Ultra R|Evolution incorporates an OLED rear-panel interface and a smartphone control app compatible with iOS, Android, and Amazon Fire devices, enabling precise adjustment of volume, low-pass filter, phase, polarity, six parametric EQs, room gain compensation, tuning modes, and power management. User presets facilitate rapid switching between listening profiles such as music, movies, and night mode.


Connectivity, Integration, and Installation Flexibility
Designed for seamless integration into both consumer and professional audio systems, the subwoofer offers unbalanced RCA and balanced XLR stereo input/output stages with wide input voltage ranges and appropriate input impedances for various source components. Additional installation-friendly features include 3.5 mm trigger input, 3.5 mm IR input, USB power output for wireless audio adapters, low 0.5-watt standby power consumption, and compliance with global safety and environmental standards, making the SB17-Ultra R|Evolution a flexible, future-ready solution for high-performance low-frequency reproduction.
