I want to get the risers for my 950's, just to widen the base so my son doesn't tip them over...but my couch isn't that high off the ground. ok..I'm not that high off the ground after I sink into the couch. I think the tweeters, with the spikes under the speakers, are slightly higher than my ears, as is. I think that adding the risers right now might screw up the soundstage. However, my center channel is 6 feet in the air, and I'm trying to angle it to get it to hit the listening position...so not all of the tweeters are at the same level anyway...(my darn room...lol)
