A:AnswerFrom my knowledge you can not add a 2nd sub. I purchased this unit with the optional surround sound speakers for my bedroom and I was surprised with the quality and sound performance. The bass sounds powerful . I do have a in my main living space a dedicated set up with a klipsh speaker and sub 7.2 set up the sub will not compare to that but it’s still an amazing and impressive sound from this LG Product.
