Bass That's More Than About Loudness and Depth: 1000-Watt KEF KF92 Subwoofer Plays with Accuracy, Balance, Detail, Dynamics, and Control While Fitting in Almost Any Space
On paper, 1,000 watts of power is an impressive number. Listen to the KEF K92 powered subwoofer, however, and you'll soon realize it constitutes a far more breathtaking figure – particularly since it's surrounded by cutting-edge technology, components, and engineering that optimizes the impact. Built to play with substantial levels of low bass all the while keeping its output controlled, natural, balanced, and detailed, KF92 will move both the air and your senses. Inside, two huge nine-inch drivers aligned in a force-canceling configuration pair with KEF's trademarked Music Integrity Engine and 1000W (RMS) of amplification. Crafted to fit in almost any space, the compact KF92 also touts sealed-box construction and a low-profile sculpted heat sink to deliver flexible positioning options as well as gripping speed, clarity, accuracy, and dynamics.
From a technical standpoint, the 44-pound KF92 hits all the right notes. Performing with extremely low distortion and high precision, the nine-inch transducers – created specifically for this model with a vented design that reduces viscous drag on movement – have a hybrid aluminum/paper cone as well as an oversized motor system and voice coil. Meanwhile, the Music Integrity Engine harnesses Intelligent Bass Extension to analyze the input signal and apply DSP to sweeten the relationship between the amplifier, drivers, and cabinet. In addition, placement-dependent EQ allows for seamless integration into any environment – be it a corner or a dedicated shelf. No wonder KF92 can operate without a hitch up to sound pressure levels of up to 110dB.
Boating a 11Hz-200Hz frequency response, KF92 will smoothly pair with any system you have. SmartConnect cleverly determines whether a mono or stereo input is being used and optimizes the gain for reference-grade performance. Speaker level inputs, a simple-to-use LFE mode, input crossover, and line-level output with a high-pass filter completes a feature set that allows KF92 to be used in any installation with minimal fuss.
Whether you're planning to pair KF92 with KEF's LSW50 powered speakers, dedicated Q or R Series, or another manufacturer's speakers, this powerhouse delivers deep, taut, precise, and faithfully replicated bass in both stereo and surround applications. 100% Music Direct Satisfaction Guaranteed.
Dual Nine-Inch Drivers Positioned in a Force-Canceling Design
Two 9-inch drivers are positioned back to back in a force-canceling design that cancels out the reactive forces which stress conventional subwoofers. The configuration keeps KF92 perfectly balanced so all you'll hear is deep, clean bass at sound pressure levels of up to 110db.
KF92's prodigious drivers are optimized with a clever vented design which reduces viscous drag on the movement of the cone, ensuring they can keep up with even the most demanding impulses.
Transducers Specifically Created for KF92
Two 9-inch KEF transducers were conceived specifically for KF92. They feature a hybrid aluminum/paper cone and an oversized motor system and voice coil. In addition, they offer vanishingly low distortion and precision, so every bass moment is uncovered even when they are working at extremes.
Music Integrity Engine
KEF's research into digital sound processing - and resultant Music Integrity Engine - is the brains behind KF92. Intelligent Bass Extension optimizes the relationship between the amplifier, drivers and cabinet, while placement-dependent EQ allows for seamless integration into any room.
Turn up the Power
KF92's 1000W (RMS) of Class D amplification (500W RMS per driver) creates immense power., delivering incredible levels of control. This improves timing accuracy and dynamic response, producing a more detailed sound closer to that in the studio.
More Bass, Less Space
KF92's compact, sealed-box construction improves flexibility of positioning as well as the speed and clarity of performance. The beautiful low-profile heatsink ensures that the hard working electronics are kept in an optimum thermal condition.
