This is what my design looks like without the AMT Mini tweeter. It is going to be run 2.1 on a Dayton KABD4100 with a battery pack module. I haven't completed designing the amp section, but this is pretty much how it looks. Should be able to cross over and EQ well with the DSP. This is my first speaker build, all the components are on the way. It is meant to teach me how to make crossovers and understand full range. If I EQ it pretty flat, the -3DB is around 26.5hz at 99.5db
