最便宜的方法，功率要求不高，只為了伴唱音樂加一點低音。先謝謝了 |

Make sure that your sub box has enough space inside. May not be the most
cost effective way to do this. |

I found something alike on ebay less expensive. Guess have to make sure
there is enough room for it, and have to cut through the back of the sub box
to make an opening. How about buy a simple mono amp to drive it, that would
be simple. |

发帖数: 565 | 5 Good question, I hope there's one that has enough power to drive it, even a
used one of good enough. |

15 inch woofer, 200W, 120dB SPL max, $150 a piece. They are decent in low
frequencies, but are not good at highs. So just eq out all highs, and you
have a usable sub. |
