Check if the issue occurs with one or all speakers.

If the issue is only with one speaker, see Quiet, intermittent or poor sound quality from one speaker.

Check if the issue is with all speakers or only the rear surround speakers.

Listen to each speaker to determine if all or certain speakers are the issue. If the issue is only heard from the rear speakers, see Poor sound quality from the rear speakers.

Determine if the problem is specifically related to bass performance.

If there is too little bass, see Too little bass or too much treble from product.
If there is too much bass, see Too much bass or too little treble from product.

Check if your speaker placement follows the recommendations for your system.

The placement of the speaker within the area affects how your hear sound from the speakers. For more info, see Speaker placement and positioning.

Determine if the issue still occurs at a lower volume.

The speaker contains an automatic electronic protection circuit to prevent speaker damage due to an overload. When the speaker detects an overload, the protection circuit engages until the overload is no longer present. If you hear this interruption, turn down the volume to relieve the overload. The speaker will resume normal play when the volume is set at a safe level.

The overload problem described here should only occur if either a) the receiver is overdriven and sends a distorted signal to the speaker or b) the Watts per channel power output of the receiver is greater than what the speaker is designed to handle.

Try a different audio device.

Connect and play another audio device through your product. This can help determine if the issue is isolated to the first device.

Be sure the speakers are compatible with the receiver.

The receiver or speakers could get damaged if the speaker impedance does not match the receiver's output. Check the specifications on both the speaker and receiver's back panel or owner's guide to be sure the components are compatible.

Be sure the speakers are connected properly to the receiver.

Check the speaker wire connections so they are wired properly and firmly to the positive and negative terminals. There should be no exposed wires as this risks damaging the receiver or tripping its circuit protection mode. Also, be sure the proper set of speaker terminals are being used; many receivers have an "A Speaker" and "B Speaker" section. See the receiver's owners guide for more information.

If the receiver can connect more than one set of speakers, try disabling one set.

Many receivers can connect two sets of speakers. On these receivers, there is often a button or switch labeled Speaker A/B that lets you hear on or both sets of speakers. When playing from multiple sets of speakers, the total speaker impedance needs to match the impedance rating of the receiver to avoid volume or sound quality issues. If more than one set of speakers is connected, use the A/B to switch to just one and see if the issue is resolved. If so, the speaker load on the receiver is likely incorrect with the added speakers.

Check for sources of interference.

Electronics can pick up interference from other electronics connected to the same power circuit or connected within close proximity. Try disconnecting the power cord from any such nearby electronics (i.e. laptop/phone charger, TV, cable box, seasonal lights, microwave, etc.). If the issue is resolved, try connecting the device or your product to a different power circuit or farther away.

Try a different set of speakers.

If you have another set of speakers that are compatible with the receiver, unplug your speakers and connect the other set instead. If there is no difference, the issue is with the receiver or speaker cables. If the issue is resolved, however, there is an issue with the first set of speakers.

Check the condition of the speaker wires and be sure they are secure at both ends.

Check the speaker wires for any kinks, scratches, cuts or damage. Replace any damaged wires and check that they are securely connected at both ends.
