You may have misunderstood what I was trying to say. I was not talking about the cabinet, your father is correct. I was talking about the sound that is coming from the tweeters, mids, etc. The sound has a horizontal pattern to it as it leaves the tweeters. If you turn the speaker on its side, that changes to a vertical pattern.
Your correct, floorstanding speakers are designed a certain way, to be floorstanding, not laying down. Now some people do use 3 m60's, m22's, or even m80's up front, but they have room to keep them all upright.
