Rated 2 out of 5 by from Mixed Had this for over a month now. Setup very quickly and everything works good except one very annoying problem. Around 10% of the time when a commercial comes on i hear a very high pitched tone that sometimes goes away when the commercial is over and sometimes stays until the soundbar is restarted. Not sure if this has to do with the comcast signal or something else.

So how or what mode do I use to connect it to my tv and turn it on as a surround system , How does the LG Sound Sync (wireless) work 

Asked by: Jrivera
The LG 1800W Hi-Fi Speaker System with Bluetooth Connectivity, Model # OJ98 has an AUXILIARY IN (Aux 1) and a PORTABLE IN (3.5 mm/headphone jack) on it that can be used for connection to extrenal devices and depending on which port you use for connection, you can select the input source with the 'Function' knob on the speaker. How you connect it to your TV will depend on what audio output connections you have on your TV. If you have an older TV that has Analog RCA Audio Out Ports (Red/White barrel ports) you can connect to either the AUX 1 or Portable In ports using the appropriate cables. If your TV only has an Optical Digital Audio Output, you will need to get a Digital/Analog converter that lets you connect to the TV at one end and connect to the auxiliary or Portable inputs on the other end. You will need the appropriate cables to make the necessary connections. Surround sound requires a set up with a configuration of 2.1, 4.1 5.1 etc and you will not get surround sound from an analog source. When you connect the speaker to your TV using the digital/analog converter, it will downconvert the signal from a digital signal to an analog signal since the speaker is not capable of digital surround. If your TV supports Bluetooth, you can also see if you can pair it to the speaker and stream audio from the TV wirelessly to the speaker via Bluetooth...^IFV

This thing is advertised as having a 15 inch woofer. Where is it? I looked at all the manuals. It only says 2 8 inch woofers with the tweeters. I want to buy this by I need to know if it really has a 15 inch subwoofer.

Asked by: Lancemomo
The area of air that these two 8 Inches speaker moves, are equivalent to the air that one 15 inches speaker move too.
