I am not sure which is which, vertical and horizontal. But, I believe it is best to use two stereo amps one on the HF and the other on the LF.
I think it is much more "sexy" to have monoblocks right next to each speaker. But, I believe it is more efficient for the amp to amplify a narrower range of frequency.
So, one stereo amp will be amping everything above 3k hz (or whatever your speaker is crossed at), and the other amp amping frequencies below that.
