Questions & Answers

Ask a Question
  • What’s the difference between this and the 210btr the one that is 149$?

    SP-210RBT has two 10" woofers as opposed to this one which has 2x15" woofers. This makes it much larger and also a little more powerful. But it also makes it a little less portable. Both speakers have 7000 mAh batteries which mean they last a very long time and they both come with a corded microphone. On the back, SP-210RBT has an EQ and X-Bass controls while SP-153BTR just has the bass and treble controls.

  • Is this speaker better than the 210bye?

    It is louder than SP-210RBT but it also much larger.
