A reason you might be getting shitty midbass with your components could be that you're not giving them enough power, that or you just need to tune your system better.
On a side note...I would recommend looking into some home audio mids. A friend of mine went from a set of $700 Rainbow components to some $30 home audio mids and they blow the Rainbows away. You just have to know what you're doing and have decent crossovers because home audio speakers can be picky. I'll see if I can't find out what brand he got if you're interested.
