Kenwood Announces XR-5S Excelon "Reference Fit" Power Amplifier

Kenwood USA Corporation announced the introduction of a third model within the Kenwood Excelon Reference Fit mobile power amplifier line.

Kenwood XR-1S

The XR-5S ($600 suggested retail price) is Kenwood’s only five-channel power amplifier and the industry’s most powerful five-channel amplifier for its size, delivering 80 watts (RMS) at 4 ohms with another 350 watts (RMS) x 1. Thanks to digital amplifier technology, the XR-5S has an extremely small chassis and allows for installation in very small spaces without any sacrifice in power or audio performance. A four-layer circuit board, surface mount device (SMD) technology and a new thermal management system make this high output, compact design possible. The XR-5S also has a continuously variable low-pass filter (50Hz to 200Hz) and continuously variable high-pass filter (50Hz to 200Hz), allowing for easy tuning and sound tailoring of multiple speaker systems from one location.

The XR-1S ($600 suggested retail price) is Kenwood’s smallest monoblock amplifier ever, delivering 600 watts (RMS) at 4 ohms and 700 watts (RMS) at 2 ohms, with a maximum power rating of 1,500 watts. Kenwood’s exclusive Dual Sigma Drive circuitry is included for improved damping factor, better musical dynamics and lower distortion. The XR-1S also has a continuously variable low pass filter (50Hz to 200Hz), along with preamp-level outputs for adding multiple amplifiers in an efficient, level-balanced and frequency-balanced manner. An optional remote bass control (KCA-WR10, $50 suggested retail price) can operate the volume of the XR-1S from the driver’s seat and will provide up to +18dB of bass boost as desired (bass frequency is variable from 40Hz to 100Hz).

The XR-4S ($600 suggested retail price) is the four-channel, full-range power amplifier solution. Power is rated at 120 watts (RMS) per channel at 4 ohms, 150 watts (RMS) per channel at 2 ohms and 300 watts per channel (RMS) bridged at 4 ohms. Advanced electronic filtering reduces the inherent noise generated by the dual power supplies, making the XR-4S an extremely musical amplifier that generates none of the harshness that exists in most other competitive full-range Class D amplifiers. Sophisticated and continuously variable low-pass (50Hz to 200Hz) and high-pass filter (50Hz to 200Hz) are included, plus a bi-amplification setting (2.5kHz to 10kHz) allows two channels of the XR-4S to operate in “high-pass” mode for tweeters while the other two channels operate in “band pass” mode to drive a mid-range speakers.

The XR-5S, XR-1S and XR-4S come with a two year warranty and are available only through authorized Kenwood Excelon retailers.
