What people are saying

Rated 5 out of 5 by from Great sound (Cinematics Effect) I got this soundbar. When you place the subwoofer a little far from the soundbar like behind your sofa. Make sure that does not miss the wi-fi out of range. You can get a great sound (a little bit) similar to surround sound. For 2.1, it's a great one.

Rated 1 out of 5 by from Waste of money DO NOT BUY!! This sound bar is a complete waste of money, I'm on the second one of this model and both have done the same where the subwoofer disconnects and re-connects constantly causing a distortion on the sound making it fade in and out and no feature to physically connect sub to sound bar. In conclusion this has been a complete WASTE OF MONEY i will never again buy an LG sound bar again!!

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

What is the Frequency Range of the unit? How deep does the subwoofer go in hz?

Asked by: Rickie01
Regrettably, neither the specifications nor the owner's manual for the LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming list the frequency range for any of the speakers or Subwoofer. Please contact our Support Center at (800) 243-0000 to inquire if they have access to the requested information...^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.

How do I get the audio to sync with my phillips TV?

Asked by: ricedream23
You can use either the Optical Digital Audio In or use Bluetooth to stream audio from the LG SL4Y 2.1 Channel 300W Sound Bar w/ Bluetooth Streaming to another device. If you are using Bluetooth, you do not have to have an optical cable connected to the unit.
