What people are saying

Rated 2 out of 5 by from Disappointed Sound quality is very poor. Remote doesn't work! Waiting for several weeks for a replacement.

Rated 2 out of 5 by from Very disappointed Loved it (especially for the price point) while it worked. However, the sound bar would no longer work after 15 months, just 3 months out of warranty. Contacted LG and tried to troubleshoot the issue (turns on, but immediately powers off), couldn't fix the problem and was basically told I was out of luck. Kind of disappointing because I have several LG products and hoped they would stand behind their product better than that.

Rated 5 out of 5 by from That's What I'm Talking About! Purchased this to replace the soundbar I had from another manufacturer. This sounder has greater clarity, more EQ options and better overall sound than its predecessor. Works well with our LG TV, and sits beneath the set without having to prop the TV up on wooden blocks. Its what I hoped for when purchasing and maybe even more.

Sometimes the soundbar will come on and play by itself even when the TV is off. How can I stop this?

Asked by: coneylis
Someone else may be pairing their device with your Soundbar &amp; turning it on after you turn your TV off. The LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming has a Bluetooth Connection Lock (BT LOCK) that limits connection to only BT (Bluetooth) and LG TV function to prevent unintended Bluetooth connection. See the Operating section on page 32 of your owner's manual for instructions on how to set this feature...^IFV

Volume control for sound bar and TV are not synced when using internal speakers and sound bar. &nbsp;In other words, my sound bar may indicate a volume of 8 but my TV will indicate something else.

Asked by: Phil77
Which TV do you have? What is the brand or manufacturer and how do you have it connected to the LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming? Is the SoundBar paired with the TV via Bluetooth or are you using the Optical Digital Audio Input on the Soundbar? Is the audio for your TV through the Optical Digital Audio Out fixed or variable? If it is fixed, it will be at the same volume level. If it is variable, it will not be at the same volume level as the Soundbar...^IFV

What the code for phone pairing Bluetooth&nbsp;

Asked by: Jackie90000
When you pair the LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming with your phone, it should appears as &ldquo;LG SL4Y(XX)&rdquo; on your phone. XX means the last four digits of address. For example, if your unit has a MAC address such as 9C:02:98:4A:F7:08, you will see &ldquo;LG SL4Y(08)&rdquo; on your Bluetooth device. When this unit is successfully connected with your Bluetooth device, &ldquo;PAIRED&rdquo; &gt; your device&rsquo;s name &gt; &ldquo;BT&rdquo; appears on the display window. Depending on the Bluetooth device type, some devices have a different way of pairing. For details about Bluetooth pairing, refer to your Bluetooth device manual...^IFV

will two of these soundbars work (sync) together via bluetooth for whole home music? meaning one in living room &amp; another on patio for example. same feed

Asked by: freer
The LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming only receives Bluetooth signals. It does not transmit them so you cannot pair it with another SL4Y Soundbar. You can add the LG SPK8-S 2.0 Channel Sound Bar Wireless Rear Speaker Kit to it but the receiver for the SPK8-S is a Bluetooth device and will have the same Bluetooth Range of 33 feet (10 m) whose range can be greatly reduced by materials in your walls, metallic furniture, your router or microwave oven, etc., &amp; the rear speakers that connect to the receiver are wired so the length of the wires will also be a limitation to how far you can place the speakers from the receiver...^IFV

what sound setting should I have my LG tv after connecting SL4Y sound bar and SPK8s wireless speakers

Asked by: dave43
The sound setting should be set for however you have the audio system connected to the TV. If by optical, you would need to set the sound out setting to Optical etc.
