Problem

Possible Cause(s)

Remedial

Action

1Speaker easily lifted from mount assembly.

2No sound heard from speakers.

3Output poor or intermittent.

4Constant buzzing, hissing, or humming.

5Poor low frequency output.

Locking hex cap screw not tightened enough.

Speaker cables not connected or damaged.

Output device (e.g., amplifier)

Damaged cables or faulty connection.

Faulty device(s) within sound system.

System grounding inadequate or suspect.

Incorrect speaker polarity connection between multiple speakers.

Following the steps on page 9, tighten the hex cap screw until it is not possible to remove the speaker.

Reconnect or replace speaker cable. Check cable routing.

Check that the output devices are plugged in and powered on.

Check that all cables are connected correctly.

Check that an output signal is present. If present, change cables and/or use a known working set of speakers.

Check that volume settings are adequately high.

Replace suspect devices with known working devices. Retry the system.

Check cables and connections. Reconnect or replace if needed.

Check all devices. Swap out and test with known working devices to isolate interference source. Replace faulty device(s).

Check grounding to devices and repair where needed.

Check polarity between speakers. Incorrect polarity (out of polarity) results in low frequencies cancelling each other out. Reverse polarity for each speaker in turn until a greater lower frequency is obtained.
