That's exactly what Bob & Rhonda said on the Hitchhiker Day and also on several times in the past eight years. Essentially not that Subs are "bad" but that Large Speakers in each location sounded better for Multichannel recordings

Several years back, I also read a different paper which essentially said that as much as we HEAR Low Frequency Sounds, our Bodies SENSE or FEEL those LF Sounds and as a result we can sense where they are coming from. This had to do with the obvious amount of energy involved in LF. This SENSE seems to me to correspond with Bob & Rhonda's comments on "Informational Cues"

So much for the theory. What about the Practice?? About eight years ago, I switched to using large speakers in a 5.1 and then 5.0 arrangement. This later became 7.0 and 7.1. Having experimented with various Subs; Sub Locations; Crossover Points; Use of Two Subs etc. I quite quickly came to realise that (for my system in my room) the use of Large speakers at each location resulted in much better Performance with Movie DVD's and DVD-A's.

Long story short, Large Speakers at each location is not the only answer but it was certainly the most pleasing answer for me
