Of course, Pi speakers are for anyone who loves music and likes to build things themselves.
The 4pi stage is the most versatile of the line up in my book. The size is manageable and the sound is big. It's capable of being explicatory and pictorial With a large soundstage and the dynamics that only a horn tweeter and low distortion cone drivers can offer you.
I suggest the 4 pi stage angled back if on the floor, or better yet placed on a small stand of 10"-14"
Cant beat the component cost with the kits and there are endless possibilities to build them in just the fashion your looking for.
