Dual ferrite magnet motor assembly weighing nearly 40lbs generates immense magnetic force and excursion of the 13.5-inch driver to produce massive low-frequency output well below the limits of human hearing.
Edge wound voice coil with eight-layer aluminum flat wire minimizes distortion and power compression while providing excellent heat dissipation and linearity ensuring precise control.
Lightweight and rigid composite cone with premium glass fiber dustcap generates massive output with pinpoint accurate frequency response.
Proprietary injection molded gasket and long-throw parabolic surround ensure longevity and allow extreme excursion and SPLs.
Sledge Amplifier – Massive Output, Sophisticated DSP, Advanced Power Management
Rated conservatively at 1,200 watts RMS, and 4,000+ watts peak power, the SB-4000 Sledge STA-1200D amplifier uses an efficient Class D design combined with fully discrete MOSFET output and a sophisticated Analog Devices DSP engine. The result is a level of effortless power and advanced processing not available from any other powered subwoofer manufacturer.
High Current Output of Fully Discrete MOSFETs with Efficiency of Class D Amplifier
The efficiency of a Class D amplifier with the ability to move massive amounts of current through the fully discrete MOSFETs enabling immense output and precise control for outstanding real-world subwoofer performance at all drive levels.
Sophisticated 50Mhz High-Resolution Analog Devices Audio DSP
The most advanced digital processor ever used in a subwoofer maintains pinpoint accuracy and pristine sound quality through advanced in-room tuning, optimized frequency response curves, powerful DSP controls, and more.
Active Power Factor Correction PFC & Ground Loop Isolation
Serves as a line conditioner, surge suppressor and voltage regulator letting the amplifier deal with wide voltage fluctuations and ensuring the subwoofers operate flawlessly on any household circuit no matter how unstable the incoming current. An isolated circuit creates a vanishingly low noise floor by eliminating the potential for ground loop hums from outside components resulting in absolute sonic transparency.
SB-4000 Smartphone App – Easiest Way Ever to Manage Subwoofer DSP and Control
Groundbreaking smartphone app works with Apple iOS® and Android® devices to unleash the full depth, force, and nuance of the SB-4000 powered subwoofer by controlling all DSP functions including volume, parametric EQ, low pass filter, phase, polarity, room gain, port tuning, custom presets and system settings.
Connects via Bluetooth for convenient control even when the subwoofer is out of sight.
3-band parametric EQ controller allows precise adjustments for frequency slope and Q factor down to the single Hz level with four different slopes, so users can improve performance by eliminating peaks, nulls, and other room issues.
Stores 3 custom presets for movies, music, and other listening experiences such as sports or gaming.
2-way feedback shows updates in real-time on both the app and subwoofer interface
Acoustically Inert and Rigidly Braced Sealed Box Cabinet Design
Inlaid front panel display, rounded edges, and a curved metal grille on the sealed box SB-4000 cabinet give it a refined yet commanding look that blends visually with home theaters and high-end audio systems. It’s sealed cabinet design results in tighter, more musical bass and make it significantly more compact than ported box subwoofers with similar specs.
Double thick 2-inch MDF front baffle and rigid internal bracing to support the massive drive unit and to ensure an acoustically inert environment.
Highly reinforced internal design and acoustic insulation eliminates all coloration or resonance from the cabinet, even when the deepest low frequencies are played at reference volume.
Protective, non-resonant steel mesh grille and custom elastomer feet for reducing noise artifacts within a room.
