FEATURES

High sound quality, high efficiency, high durability, and low distortion.

Magnetic circuit employing a large, 200 mm diameter ferrite magnet reproduces powerful low frequencies.

Ultra linearity in super low frequencies assures the cone displacement limit of 40 mm (peak-to-peak).

The bobbin and the voice coil are designed with emphasis on the heat radiation and mechanical strength, achieving high

power handling capacity (500 W).

Linear displacement characteristics thanks to high damping materials incorporated in the edge and resin-reinforced

cone.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could

result in death or serious personal injury.

Avoid installing or mounting the unit in unstable locations, such as on a rickety

table or a slanted surface. Doing so may result in the unit falling down and

causing personal injury and/or property damage.

Install the unit only in a location that can structurally support the weight of the

unit and the mounting bracket. Doing otherwise may result in the unit falling

down and causing personal injury and/or property damage.

CAUTION

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

Do not place heavy objects on the unit as this maycause it to fall or break which

may result in personal injury and/or property damage. In addition, the object

itself may fall off and cause injury and/or damage.

Do not stand or sit on, nor hang down from the unit as this may cause it to fall

down or drop, resulting in personal injury and/or property damage.

Do not operate the unit for an extended period of time with the sound distorting.

This is an indication of a malfunction, which in turn can cause heat to generate

and result in a fire.

Avoid placing the unit in a doorway or other high traffic area as people may trip

on the equipment and cords, orbe injured by falling objects.

TOACorporation

Install the unit only in stable locations, and make appropriate arrangements to

prevent it from falling down or rolling across the floor. If it falls down or moves,

this may cause personal injury and/or property damage.

When unpacking or moving a heavy unit, be sure to handle the unit with two or

more persons. Falling or dropping the unit may cause personal injury and/or

property damage.
