The source describes overload and overheating protection; confirm the exact protection functions in the current manufacturer's manual. Specifications are supplied listing information, not independent test results. No distortion-free performance or protection against every type of equipment damage is guaranteed.

Speaker Compatibility

The existing description identifies 18-inch and 21-inch drivers as intended applications. Driver diameter alone does not establish compatibility. Have a qualified installer verify the driver's impedance, power handling, enclosure design and connector wiring. Ratings are provided for 4-ohm and 8-ohm loads; do not assume operation below 4 ohms is supported. This panel is intended for bass reinforcement, not full-range playback.

Dimensions and Installation

• Listed panel height: 33cm
• Listed panel width: 19.6cm
• Listed depth: 11cm
• Approximate equipment weight stated in the source: 3kg

These are equipment figures, not verified packed shipping dimensions or shipping weight. Confirm the mounting cutout and clearance requirements before modifying an enclosure. The source recommends a recessed wooden mounting compartment to secure the panel and reduce exposure to internal vibration. A qualified technician should confirm mounting, vibration isolation and cooling requirements against the current manual.

Electrical Safety and Care

• Professional installation is recommended. Verify mains voltage, frequency, input-current requirements and grounding on the equipment label before use.
• Have an electrician check the circuit, wiring, outlets and protective devices. Audio output power is not the same as mains power consumption.
• Automatic dual voltage does not establish compatibility with every country's electrical supply or every installation.
• Avoid extension leads. If one is necessary, have an electrician select an appropriate current rating and cable size for the installation and lead length.
• Disconnect mains power before installation, wiring or servicing; refer internal servicing to qualified personnel.
• Keep dry, maintain ventilation and use hearing-safe listening levels.
