What People Are Saying

Rated 5 out of 5 by from Tremendous sound! I am extremely pleased with this sound system which really rocks the entire house. I bought this brand because I knew that it was manufactured to be high quality and I went with this model because it was the most powerful shelf stereo system that I could find and still afford. The fact that it plays CD's and also works with bluetooth makes it a versatile system which can be driven from my laptop or smartphone and I love that.

Rated 5 out of 5 by from Fantastic Features! I bought the LG CM4550 Mini Shelf System about one year ago, and I am very pleased with its performance, very good stereo system. I really missed the headphone jack though. There are times when I would like to listen without bothering anyone.

Rated 4 out of 5 by from Loud, Clear and Versatile! I purchased this unit for my garage at home and it plays any genre loud and clear. The only thing is I wish you could adjust the EQ settings a little more, but other than that the few preset EQ's are good enough.

Is there any extension wire for the for the subwoofer available or do I have to cut and splice it?

Asked by: spaniky
Hi Spaniky. LG does not make any extension wires for the Subwoofer on the LG 700W 2.1ch Mini Shelf System with Built-in Subwoofer and Bluetooth&reg;, Model # CM4550 so if you need a longer wire, cutting and splicing it would be one option, or you could get a roll of 16 gauge or 18 gauge wire from a Consumer Electronic Retail Store like Best Buy or Radio Shack and get the telephone type connector from Radio Shack and crimp the longer wire into it . The rolls are available from 25 feet and up...^IFV

Asked by: Evan2345
We appreciate your interest in this audio system. The unit would only provide one address for Bluetooth connections. Have you connected to another unit previously?

I have an older model flat screen LG tv, just received this system. Aux cords aren't working. Can't find anything in audio settings on tv. How would I connect this? USB? That optical port thing?

Asked by: LotusNyx
It would not be possible to get sound from the LG TV using a USB connection. The best option would be using the optical port on the unit and changing the sound settings on the TV. If you require further assistance, please contact us at 800-243-0000.
