In ported enclosures, the farther below tuning, the lower the pressure and the greater the cone movement. In my car the sub barely moves at 22hz and the cone is controlled from about 17-28hz very well. The cone moves the least at 22hz but that's where the most output is... hmm that seems to go directly against what you're saying... I guess cone movement is not a good sound meter huh?</p></blockquote><p></p>
