Various factors may cause muffled surround sound, but some are considerably more noticeable than others.

Deficiencies in Audio

The most apparent reason for distorted surround sound is the presence of an obstruction. Make sure your audio system speakers aren’t blocked while putting them up. This implies that you should avoid placing anything huge between you and the speakers to prevent the sound waves from being absorbed. Though this won’t significantly reduce sound quality, it may reduce the crispness of pricey speakers.

Having lots of room behind and in front of a speaker might benefit some. For subwoofers, this is especially true since they have cones at the rear that draw in air. Due to the lack of room, their audio quality may be affected. You should always adhere to your surround sound setup manual for the ideal speaker placement.

Wiring Concerns

Incorrect wiring is the most prevalent cause of muffled surround sound speakers. Connecting speakers might be difficult if you’ve never handled it prior, but it’s critical that you do it correctly.

Speakers must be wired in series, which is also known as phase. For this method to work, you must use a positive lead on your amplifier to link to the first speaker and a negative terminal on your last speaker to link up to your amplifier.

High-quality audio with minimal interference may be produced by a correctly connected surround sound system. Wiring mistakes may cause difficulties with the audio output, just like every other electrical system.

When surround sound sounds unpleasant, it’s usually because a connection isn’t functioning right. A speaker that has its positive and negative wires reversed can generate muted or entirely absent sound in the system.

Even if the speaker’s wires are damaged or not attached correctly, this might also be the case. You should inspect the wiring first, if you notice that your surround sound is muted. When wires are wrapped around furnishings, they are especially vulnerable to harm.

Using Improper AV Receiver Settings

The final source of muffled surround sound is that your AV receiver or any other multimedia equipment isn’t configured to the proper settings for your setup. If you’ve just purchased a new speaker system or media player, you may discover that the settings have been altered.

You may notice a decrease in your sound quality if you don’t have a center channel in your speaker system. To avoid audio distribution errors, it’s possible that your receiver or media player misunderstands the number of speakers you really have. As it turns out, this is a rather straightforward issue to solve.

Just to be sure, fiddle about with the receiver configurations for a while to make sure everything is set up well. Many receivers, for instance, lets you customize the size, quantity, and crossover parameters of your speakers and subwoofers. Most receivers’ preset settings may not be the best fit for your specific installation.

Any of these factors may cause the muffling of a surround sound system. If you have this issue, it’s worth fiddling with your system and making sure everything is linked correctly. It’s likely that you’ll discover something has been smashed or that the parameters have been altered.


Numerous methods may be used to avoid distorted sounds from a speaker. Rearranging the speaker, utilizing a unique material surrounding the speaker, or utilizing a sound amplifier are just a few of the options. Avoiding speaker muffling may be accomplished by keeping the speakers away from flat objects.

You may lessen the speaker’s vibrations by using a foam pad, or a scrap of paper rolled into a ball. Rubber bands may also be used to secure the speaker to the table.
