[QUOTE="tangmonster, post: 72889, member: 1581"] Here is some extra ideas of a build i did recently: http://www.diyaudio.com/forums/subwoofers/165628-my-first-build.html i basically put two no-name 12" drivers in a sealed enclosure. I started measuring with a microphone frequency response. Then I built a linkwitz transform and eq'd the !@#$ out of it so it goes down to 20hz. I also added a 2 channel parametric filter to smooth out two "bumps" in the response. I then built a 300W amp to drive it : Here are pictures of the amp: http://www.facebook.com/#!/album.php?aid=235530&id=607902362 Note strip board with linkwitz transform and parametric EQ. The linkwitz circuit transformed the speaker from being crappy to AWESOME. I suppose with better speakers it would have been less usefull :) [/QUOTE]
