Could some one please help me to choose which speakers/soundbar I need help for me to hear my TV better. I am having hearing problems and find it difficult to hear some of the speech on my TV. I have a Panasonic 42tx 400 TV. I am elderly and do not need it for any other reason other than speech enhancer. I have looked at the Canton DM55 but my son has said that this is more than I need and it is a lot of money. Can someone advise me please
