Speaker height...should known better


The other day I was listening to my system sitting down on my chair on my computer when all of sudden I had lower my head to glimpse a song on my screen when I realize, wait this sound much better. I have only lowered my head a few inches or 3 and all of sudden the music sounded way better. So much better to a point where it sounded coherent, phase timed and much more dynamic. I thought for a long time I have placed my Triangle BR03 tweeter at ear level. From the perception view from the listening position I would if thought it was at ear level. I was wrong. Currently my ears level is 3 inches above the tweeter(about the top of the cabinet). When I bought the speakers stands a few years ago, I got them new for my other speakers that were smaller. The current height on the stands are 28". I think what need now are at least 31". No wonder my measurements had a gradual roll off of the high end at around 8k at a couple of speakers I had. Now I am planning on getting higher stands to hear the difference.

@larryi + 1 - my Marten Parker Duos are a case in point; those are designed to be on high stands, with the tweeter quite a bit over ear level, which is more along the axis of the middle of he lower speaker. Never seen one designed like it, but it sure does work....

@larryi  Yes, you are right. I could just use trial and error with the tilt but for information purposes, it couldn't hurt to know mathematical  portion of it. Yes many speakers are voiced differently and that is why many people have different opinions on how a speaker sound say on a same model. Factors like acoustics, sitting position, sources, etc all play come into play. Most of it has been corrected at the moment for me and now with this new tweak, not to mention it was free, made a HUGE difference. 

, , , and cohesion in my listening environment if I move my listening chair even an inch or so forward or backward.

@larsman Thx!   

I have an asymmetrical listening space.  The tone/timbre & dynamics are quite nice.  But a cohesive soundstage for orchestral music has been a challenge.   After reading your post, I tweaked my speakers placement again for the umpteenth time.  This time I got lucky.   3-D width & depth.  The repositioning was only a few inches.  🎉
