I have heard several sound bars. I don't know what brand or model they were, but I do know that none of them were really high end or expensive. Of the ones I've heard, they all seem to display the same trait; the sound bar itself has sounded good to me, as good or better than the regular speakers used in a typical surround sound system, but the subs that come with them lack the power and punch I'm looking for. I'm used to running a separate powered sub of substantial size and power (i.e. 15" driver and at least 250 watts), so none of the subs that come with the sound bars are going to work for me. I am finding out the only sound bar systems that are capable of connecting to wireless speakers don't have a wired sub out. They can only be used with the wireless sub that comes with them. So my only option appears to be trying to find a sound bar that simulates surround sound. The one my bro-in-law has does this and it seems to do a good job doing it. I can live without rear speakers easier than I can do without a powerful sub...
