Jim, I hear that from folks, but honestly, it's much larger than a foot or so. Everyone on the couch in my house enjoys them greatly. Like many great speakers, the sweet spot is smaller than others. There are always tradeoffs with any speaker build. Richard has chosen the best sound he can give you in it's price range, but that means that it won't be a sweet spot for the whole room. I find most speakers with large sweet spots to be unfocused a bit with no true sweet spot if you would. Again, this is a general thought as I think through my recent auditions. I know that recently at an event for the 7s, the sweet spot was very large. Larger than I remember it being for the mk 1's. I also think that the Niagara 7000 made part of that difference as we all felt the sound stage was larger and more realistic than usual. I try to always take the time to maximize the room acoustics when I'm able to. After that I do take the time to dial in my speakers. I've always had a sweet spot for two if you would, but the rest of the room never seems to suffer at all. I'm the only one who ever listens critically and even then, I enjoy the music so much with the Vandersteens, that I won't have a problem with the sweet spot, but that's just me. Most audiophiles I speak with Jim, seem to listen alone when it's critical time. It's going to be a personal thing of course, but honestly, for the price if you want a special sounding speaker, the Vandy's will give the critical listener a great sound and that's why he has and continues to be the sales leader in these price categories.
Not saying you are wrong, but its' one of the trade offs and none of us who have them for long periods of time seem to have that problem. :)
