L22 laid on its side (can you do that?) would be 28" wide and 14" tall then. Horizon on top of that (23" wide) with perhaps an IsoAcoustics Aperta 300 between them. Assuming something is placed under the L22 (aurelex subdude(s), IsoAcoustics pucks, etc.) All in, total height would be around 30". Get the benefit of angle adjustment due to the Aperta. Craziness? I think that would look pretty imposing (badass), but not if there are sonic compromises.
