I ordered the Samsung Harman Cardon 5.1 HW Q6CR/ZA (soundbar and subwoofer)

It was just OK. Not as full sound or loud as I wanted it to be. Not bad for the price: $229 refurbished from Amazon.

Anyone know of a louder/fuller option at a decent price. Or a speaker setup that would rock the house a little better?

Is connecting soundbar through optical cable or HDMI better?
