2.1/ 5.1 speakers 的電路板, 藏在超重低音的音箱內, 這種設計有無問題?

I believe that this is a way to attract rookies when they do not want an independent amplifier. Although sub-woofer has its own amplifier anyway, making it even for decoding of dts or Dolby Digital signal is not a good idea as it makes the sub-woofer too heavy loaded.
