WARNINGS

THERE ARE NO USER-SERVICE­ABLE PARTS INSIDE ANY KRELL
PRODUCT.

Thank you for your purchase of the Resolution Subwoofer, a powered subwoofer in
the Resolution Series of loudspeakers.

The Resolution Subwoofer delivers large amounts of sustained low frequency infor
mation without reservation. Excellent cabinet construction, robust driver selection
and 650 watts of genuine Krell amplification combine to offer the huge output, speed
and resolution necessary for the ultimate home theater or music system experience.

The Resolution Subwoofer features a one-inch MDF enclosure with 2-inch thick front
and rear baffles. The sealed box design promotes clean, accurate bass. A separate
control cavity completely isolates electronics package from the driver.

The single 15-inch driver has a very stiff, reinforced polypropylene cone. Peak to
Peak linear travel is 1-3/8-inch, and the voice coil is extra long. Motor geometry fea­tures a focused magnetic field that promotes control and lowers distortion.

The 650 watt Krell Current Mode power amplifier is a Class AB design featuring a
1000 watt transformer and 55,000 microfarads of filter capacitance. Class AB amplifi­cation provides power quickly and sustains power indefinitely, thereby providing
complete control of the driver under the most demanding conditions.

This document outlines the basic steps for unpacking, placing, connecting, and oper­ating the Resolution Subwoofer. The owner’s reference for this product, including a

Each Resolution Subwoofer requires at least 2 inches (5 cm) of clearance on each

of the subwoofer for adequate ventilation. The subwoofer delivers excellent per­formance in nearly any location in the listening room. Two placement options fol­low:

Option 1: Stereo. Place the Resolution Subwoofer midway between the left and
right loudspeakers.

Option 2: Home Theater. Place the subwoofer in a corner of the room, preferably

require a dedicated AC circuit. Operate the subwoofer only with the power cord
supplied.
