Speaker Tilt Back benefits?

Thanks, y'all!
I'm buying new spikes because the old set was lost in a move, and I was using inferior and cheap spikes - had one of those "aha" moments the other day and realized new spikes would probably improve the sound quite a bit. I've just tried just tilting them back a little using some mouse pads under the front outriggers, and I liked the sound; seemed to be a little more airy high end and better rhythm to the music. Could be some of that time align theory at work, or just a better balance for my room as GS5556 suggests. I'll try it with the spikes when they arrive and report back!

The Mapleshade speaker stands utilize a tilt, and the stands are really a misnomer as they are a few inches off the floor. When used with the Reference 3A de Capo i's this improved the bass response and soundstage and the sound just got better from these speakers. L'wood

Some speakers have tweeters below the woofer, and some (MTM) have the tweeter in between two woofers.

Tilting speakers back reduces the LF bounce off the floor. It also discourages people from setting drink glasses down on the top.

What sounds better will largely depend on your room acoustics, listening position and the vertical dispersion pattern of the speaker. There is no "rule of thumb" for this....just experiment. If a slight tilt makes a significant difference then this would indicate a problem somewhere....either room acoustics or the speaker. In this case, you may want to try to fix the root cause....

This may sound crazy, but I've got the Virgo II's little brother, the Spark. I have used a different approach in my room. I listen about 6ft from ear to midwoof, and 8ft apart, so I'm in the nearfield. Anyway, the soundstage depth is so good-it starts at the plane of the mains and goes back from there. I actually tip the speakers forward, not back and it seems to increase the height of the stage. Obviously YMMV, but I swear I've seen this in pics under member systems where a fellow had the Virgo II's tipped forward, so I have a feeling I'm not the only one doing this. Hope this is some help, don't mean to confuse, just explaining my results. -Fish
