Installation

Unpack and inspect contents. Choose a suitable location protected from direct, heavy water exposure (e.g., under an eave).

  1. Mount the speaker: Use the integrated bracket to mount on a solid surface using appropriate hardware (not included).
  2. Run speaker wire: Use 16-gauge or thicker outdoor-rated speaker wire. Leave slack for connection.
  3. Connect wires: Strip 1/2 inch of insulation, connect to gold-plated binding posts (observe polarity: + to +, - to -).
  4. Secure connections: Tighten binding posts and ensure no bare wire is exposed.
  5. Aim the speaker: Loosen bracket knob, aim speaker for optimal coverage, then retighten.

WARNING! Ensure mounting surface can support the speaker's weight. All electrical connections must be made with the amplifier powered OFF.

First-Time Setup

After installation, configure your audio system.

  1. Connect to amplifier: Ensure amplifier is compatible (4-8 ohm load, adequate power).
  2. Set amplifier volume: Start with low volume on your amplifier or source.
  3. Test sound: Play audio and gradually increase volume to a comfortable level.
  4. Fine-tune aiming: Adjust speaker direction for best coverage in your listening area.

CAUTION! Do not overpower the speakers. Exceeding 100 watts continuous power may cause damage.

Specifications

Controls and Connections

The speaker itself has no user controls. All audio control is performed at the connected amplifier or source device.

Connections: Gold-plated, 5-way binding posts for secure speaker wire connection. Accepts bare wire, spade lugs, or banana plugs (single only).

Amplifier Requirements: Stereo or multi-channel amplifier/receiver capable of driving a 4-8 ohm load. Ensure total impedance of all connected speakers is within amplifier specifications.

Connecting to an Amplifier

For stereo or multi-zone audio systems.

  1. Turn off and unplug the amplifier.
  2. Identify amplifier speaker terminals: Locate the correct output channels (e.g., Zone 2, Surround Back, or Main).
  3. Run wire: Connect one run of speaker wire from the amplifier's positive (+) terminal to the speaker's positive (+) terminal. Repeat for negative (-).
  4. Repeat for additional speakers in the system, observing proper impedance load on the amplifier.
  5. Power on amplifier and test at low volume.

Tip: Use a wire gauge appropriate for the run length (16-gauge for runs up to 50 ft, 14-gauge for longer runs).

Operation and Performance

Once installed and connected, operation is seamless.

  1. Power: Control power and volume from your amplifier or system controller.
  2. Sound Quality: The Articulated Array provides consistent sound over a wide area. Bass response is reinforced by placement against a solid surface.
  3. Multi-Speaker Setup: For larger areas, multiple pairs can be used. Ensure your amplifier can handle the total impedance.
  4. Source Selection: Play any audio source connected to your amplifier (streaming, TV, music player).

WARNING! Avoid driving the amplifier into distortion (clipping), as this is a primary cause of speaker damage.

Weather Resistance & Care

Designed for outdoor use but benefits from some protection.

Cleaning: Wipe exterior with a soft, damp cloth. Do not use harsh chemicals, abrasives, or high-pressure water.

Winter Care: While weather-resistant, prolonged exposure to direct, driving rain or snow accumulation is not recommended. If possible, cover or relocate speakers in extreme winter conditions.

CAUTION! Do not submerge speakers. Ensure wire connections are protected from direct water exposure.

Troubleshooting

SymptomPossible CauseCorrective Action
No sound from speakerAmplifier off/incorrect sourceEnsure amplifier is on and correct input source is selected. Check volume.
Intermittent or distorted soundLoose or corroded connectionsPower off amplifier. Check wire connections at both speaker and amplifier. Clean if corroded.
Sound from only one speakerWire fault or amplifier settingSwap speaker wires at amplifier to test if problem follows the wire/speaker. Check amplifier balance settings.
Weak bass or thin soundSpeaker placementEnsure speaker is mounted on a solid surface (wall, eave) to reinforce bass. Adjust aiming.
Amplifier shuts down or overheatsImpedance mismatch or short circuitVerify total speaker impedance is within amplifier's specified range. Check for bare wires touching.

Service: For product service, contact Bose Customer Service or an authorized Bose dealer. Do not attempt to open or repair the speaker enclosure.
