Rated 4 out of 5 by from Great sound quality Bought this sound bar a little over a year ago and I must say I haven't regret it. The sound is on par with systems that cost a lot more. I'm looking to add more pieces such as the H7 and H5 to see what more this system can do. Awesome product!

Rated 3 out of 5 by from Good but not great yet I had my first unit for about 7 months before the soundbar stopped connecting to the subwoofer. The overall sound quality is good, but the subwoofer needs to be a lot closer to the soundbar than I would like. The soundbar is on top of my mantle and the subwoofer is almost directly below it.

Rated 5 out of 5 by from Excellent picture Bought this TV a few weeks ago and the picture looks awesome. The size and picture quality is unbelievable. This is my second LG TV, first one was a 40" for the guest room which includes an LG soundbar and a PS4. This was purchased last year. I just purchased the 65" with the magic remote for the living room and I love it. Easy to hang and easy to set up. I just installed the 4.1 LG soundbar. I recommend LG all the way. Hopefully I get the LG 3D DVD player for Christmas to complete my set up.

Rated 3 out of 5 by from wireless sub issue The sound of the bar and sub is very good. but I just can't get over the sub issue. The sub is about 6' from the sound bar and the sub lose connections all the time. It might be for only a few sec but during a movie it will drive you mad.

Hi,  I have an LAS751M sound bar with the wireless subwoofer and was wondering if I could pair a second wireless subwoofer to the sound bar?

How do you hook up the sytem

Asked by: Jet2127
We appreciate your interest in this Audio System. Begin the setup by connecting the power cable to the DC IN port. It is next suggested to connect the OPTICAL IN (OPT. IN) port to the TV using an OPTICAL Audio Cable. Once this is complete, follow the instructions on pages 14 and 15 to set up the Subwoofer.

Where would be the best place to put my sub? 

Asked by: JoeR92
The closer the distance between the main unit and the subwoofer, the better the sound quality may be experienced. It is recommended to install the main unit and subwoofer as close as possible to avoid such difficulties as obstacles between the devices or signal interference caused by other wireless devices, medical equipment, microwave ovens or wireless LAN device.

I have a LG music flow sound bar. When watching tv the sound bar be working fine then all of sudden it will start making loud snowy sound. The sound will continue until you switch functions. The only function that will connect to the tv is hdmi in. 

Asked by: Smg1976
We regret the inconvenience you have experienced with this Audio System. It is normal for the HDMI port to be the only connection available if there are no other devices attached to the system. It is NOT normal for the system to break into static. The unit may require service. Please contact our Customer Interactive Center at 800-243-0000 for additional assistance in this matter.
