Understand what you are saying.I'm just telling you that my personal experience in comparing an omni with a stereo sub system is that the stereo sub system beats it out in perceived quality of the bass in the music presented, at least in the homes where I heard them.
I've no doubt that you are right; my ears also present me with a different view. Now, I've never heard an omni system with 5 subs spread around the room. Perhaps I should keep my current system and ad 3 or so spread around the room.
Of course If I were to add 4 more subs to my ccurent array bringing up a true bass line array to go with the 34 mid ranges and 60 tweeters, that would be A SOUND SOURCE THAT IS VERY LARGE.
