    DIY Dayton Audio 18" Ultimax Sub Kit (UM18-22 and Denovo Flatpack)

    Sonnie, thanks for the reply. Do you use or need EQ to get a flat response down to 20 hz and below? Or do you accept the natural slope fall off below resonance? GL

    DIY Dayton Audio 18" Ultimax Sub Kit (UM18-22 and Denovo Flatpack)

    What ever happened with the twin UM22-18 subwoofers? Specifically, what is their low-end extension? Do they go below 30hz? I'm curious because I use a single UM22-15 in a 16ft transmission line and can only get down to about 25hz before I hit the excursion limit of the suspension at about 90dB...
