Speaker Set-Up: Use of a Plumb Bob


Kinda curious if it is important to ensure that speakers are vertically positioned by using a plumb-bob or similar tool (e.g., bubble-level). If so, aside from avoiding listener dizziness or eye strain (LOL), ... why? Does it affect performance in some way??

Thanks and Happy New Year.

Zd542, I unscrewed the rear spikes to lift the back of the speakers, thus tilting them forward and pointing the tweeters more directly on axis towards my ears when I sit in my listening chair. I can only tilt the speakers forward by so much because their center of gravity is high and close to the speaker fronts. I am concerned that too much forward tilt could increase the risk that the speakers might fall over. This adjustment is not the subject of my question.

Rather, looking straight at the speakers face-on from my listening chair, I can see that the speakers lean sideways because the slab floor isn't level. I tried the best I could to straighten the left/right tilt with shims and by adjusting the spikes. My question is how critical is this adjustment. I think Vandy owners spend a lot of time with this adjustment. I was wondering just how critical it really is.

Thanks

If you do as you have, the difference is probably infinately small & even un noticable. Less than if you have one in an awkward spot in a room, meaning the area has an open door close by or an L shape or a bunch of other things. Get them as close as possible to the ideal. Rugs & funiture should also be considered.
I'll try the plumb bob. Most of the time I just use a tape measure to properly situate my speakers.
