What People Are Saying

Rated 2 out of 5 by from Disappointed When I installed these speakers it was good for a few days. Now they fade out every couple of minutes. What was once an enjoyable experience has become one of frustration.

Rated 1 out of 5 by from When it works! First I bought the soundbar and woofer sj5 but was still having trouble hearing clear dialogue so the hubby recommended buying the rear speaker set. The rear set was problematic out of the box. The sound drops out every 30-45 seconds! Very frustrating since everything is mounted on the wallls. Contacted support and was told to "get a new set". I have read many reviews about the same problems and LG obviously knows this is a problem and they should fix it or stop selling a faulty product.

Rated 5 out of 5 by from Great Package product I bought the sj5 sound bar to go along with my new b7 oled and go these as a package with the sj5 soundbar. The people claiming these are not wireless dont know anything about surround sounds. It has its own reciever and does not have to have wires ran to the main reciever(sound bar or sub). This lets you place these in the rear of the room with just a simple outlet plug in. These added great sound! *i did have a problem with these cutting in and out at first but found it was due to me blocking the reciver boxs signal and once i moved it to a better location problem was solved.

Rated 1 out of 5 by from NOT wireless These were included as a throw-in at Best Buy when buying SJ5Y soundbar. Lo and behold as previous reviewer noted the speakers themselves are not wireless. Taking soundbar and speakers back....

Rated 2 out of 5 by from Disappointing Advertised as wireless. Is simply an additional wireless hub with two WIRED connections.

Rated 5 out of 5 by from You need these If you buy the LG SJ4Y or SJ5Y soundbar you need to buy these so the soundbar is not searching for them. They pair instantly and the surround sound they create is terrific. The speakers themselves are wired to the receiver unit which is connected to the soundbar wirelessly.

Can I put the rear speaker wireless connector in the basement and run the wires through the wall or does it have to be close to the sound bar .

Asked by: 617 Mike
The wireless receiver that the rear speakers for the LG 2.0 ch Sound Bar Wireless Rear Speaker Kit, Model # SPJ4-S plug into has to be paired to the main unit for the compatible Sound Bar that you are using with it. It has to be within 33 feet (10 m) of the Sound Bar. Depending on what materials your wall is made of and if you have electrical wires running through your walls or other factors that interfere with the signal, you might not get a signal at all. The closer to the Sound bar you are within it's given range, the better the signal...^IFV

Will the SPJ4-S pair wirelessly with the LASC47 sound bar? It states on the LG page for the LASC47 that it can be upgraded to surround sound by adding the SPJ4-S, but I've seen in answers to questions that the SPJ4-S only pairs with the SJ4Y and SJ5Y.

Asked by: TheBBO
Please accept our apologies for the answers on the page for the LASC47 that state that it is not compatible with the SPJ4-S Rear Speaker Kit. The LASC47, SJ4Y and SJ4Y-S all share the same manual and they are all compatible with the SPJ4-S Rear Speaker Kit.

What kind of speaker wire would I have to buy if I needed them to be longer to be able to mount these spj4s to the wall?

Asked by: Denisse
You can use any gauge of wire for the speakers as long as it will fit into the alligator connectors in the back of the speakers. The gauge of wire that is commonly used for small speakers like this with alligator connectors is usually 18-gauge or 16 gauge. ^AC
