[QUOTE="Ivan Beaver, post: 26523, member: 30"] Re: Subwoofers with 30hz performance. When measuring freq response (to see the extremes) there should be no high or low pass filters engaged. If measuing overall performance, you could use the manufacturers filter specs-but be carefull if they recommend a boost down low or up high, as this can really throw off the max output capability of the box. If you add a 10dB boost to extend the low freq (pretty common on some boxes) then you have to SUBTRACT that same 10dB from the max output-if you are talking about the low freq capability. You don't get the boost for free. [/QUOTE]
