KEF KC62 Uni-Core 6.5" Dual Driver Powered Subwoofer 1000W BLACK
The KEF KC62 is an exceptionally compact powered subwoofer engineered to deliver deep, powerful and accurate bass from a remarkably small enclosure. Featuring KEF's innovative Uni-Core force cancelling technology, the KC62 combines two 6.5-inch drivers with 1,000 watts RMS of Class D amplification to produce low-frequency performance that defies its dimensions.
Designed for premium stereo music systems and home theatre installations, the KC62 delivers bass extension down to 11 Hz (±3 dB) with a maximum output of 105 dB. Advanced driver engineering, intelligent digital signal processing and extensive connection options provide exceptional performance and flexibility in virtually any listening environment.
Finished in Carbon Black, the KC62 features a beautifully curved, sealed aluminium cabinet that combines a sophisticated appearance with outstanding structural rigidity. Its compact footprint allows it to fit discreetly into living rooms, entertainment systems and dedicated listening spaces without sacrificing bass performance.
Uni-Core Force Cancelling Technology
At the heart of the KC62 is KEF's revolutionary Uni-Core driver technology. Unlike conventional dual-opposed subwoofer designs, Uni-Core combines two opposing drivers into a single shared magnet system, with their voice coils arranged concentrically.
This innovative configuration allows the enclosure to be more than one-third smaller than a comparable conventional design while maintaining or exceeding the driver excursion needed for powerful low-frequency reproduction. The force cancelling arrangement also minimizes cabinet vibration, allowing the KC62 to deliver clean, controlled bass from an extraordinarily compact enclosure.
Twin 6.5-Inch Drivers with P-Flex Surrounds
The KC62 features two 6.5-inch drivers equipped with KEF's P-Flex pressure-resistant surrounds. Inspired by the folding principles of origami, the uniquely pleated surrounds are designed to resist the substantial internal air pressure generated within the sealed cabinet.
This specialized construction allows the drivers to move accurately without the excessive resistance associated with conventional surround designs. The result is improved bass extension, exceptional control and precise reproduction of demanding low-frequency passages.
Smart Distortion Control Technology
KEF's Smart Distortion Control Technology employs an advanced sensorless feedback system that monitors current within the driver voice coils to identify and correct nonlinear distortion.
By continuously analyzing driver behaviour and applying corrective processing, the system can reduce total harmonic distortion by up to 75%, allowing the KC62 to reproduce bass with greater accuracy, clarity and natural tonal balance.
Music Integrity Engine with Intelligent Bass Extension
The KC62 incorporates KEF's proprietary Music Integrity Engine, a sophisticated collection of digital signal processing algorithms designed to optimize the relationship between the drivers, amplification and acoustic enclosure.
Intelligent Bass Extension (iBX) dynamically extends low-frequency performance, while SmartLimiter continuously analyzes the incoming signal to help prevent clipping and maintain controlled operation. These technologies work together to deliver exceptionally deep, detailed and consistent bass across a wide range of listening levels.
1,000 Watts RMS of Class D Amplification
Each Uni-Core driver is powered by its own 500-watt RMS Class D amplifier, providing a combined output of 1,000 watts RMS. This substantial amplification gives the KC62 the power and control required to reproduce demanding bass transients with exceptional authority.
Whether reproducing the subtle low-frequency detail of acoustic recordings or the explosive effects of a movie soundtrack, the KC62 provides powerful, responsive bass without requiring a large conventional subwoofer enclosure.
Versatile Connectivity and System Integration
The KC62 is designed to integrate with a wide variety of stereo amplifiers, AV receivers and home theatre systems. RCA line-level inputs and speaker-level inputs provide compatibility with different amplifier configurations, while RCA line outputs with an adjustable high-pass filter support more advanced system integration.
KEF SmartConnect technology simplifies connection to compatible equipment, while adjustable low-pass and high-pass crossover controls allow the subwoofer to be carefully matched with the main loudspeakers.
For installations requiring wireless placement, the KC62 is compatible with the optional KEF KW1 wireless subwoofer adapter kit, sold separately.
Five Room Placement Equalization Modes
The KC62 features five preset Room Placement Equalization settings to optimize bass response according to its location within the listening environment.
Available configurations include Free Space, Wall, Corner, Cabinet and Apartment modes. These settings help compensate for the acoustic effects of different placements, allowing the KC62 to maintain balanced, controlled bass whether positioned openly in a room, close to boundaries or inside furniture.
Compact Sealed Aluminium Construction
The KC62's precision-engineered sealed enclosure is constructed from extruded aluminium, providing a rigid and durable foundation for its powerful opposing drivers.
Measuring only 246 x 256 x 248 mm (9.68 x 10.07 x 9.76 inches), including the rear panel and feet, the KC62 offers exceptional placement flexibility. Its curved exterior and Carbon Black finish make it an elegant addition to both contemporary and traditional audio systems.
