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.

You could always put a ribbon tweeter on top.parts express 50$each .you can adjust it to your seating position. This is why I like line arrays cuz no matter where you are ,sit or stand there always there. Enjoy the hunt and the experience and the music

It seems like he’s sitting in nearfield. He can tilt it, turn it upside down, do a 360 with it,  whatever, doesn’t take away from the fact it is a terrible design.....letting that very mediocre woofer get all the way down to 70, 60 hz and all the way up to 3600hz is just a bad idea....a lot got compromised w.r.t achievable fidelity. He may salvage something by bass managing, preventing that woofer from moving too much, rolling it off around 120hz to a subwoofer pair (needs to be a pair to help prevent localization with a high sub crossover of 120-ish hz)...still a terrible li’l box.

On the other hand, a Andrew Jones speaker (suggested as a replacement earlier) with a point source concentric driver, 4 inch mid covering 260 to 1800hz before hand off to the tweeter....A woofer taking over 260hz and under kept that mid driver very stress free.... Especially for near field, it seems like a very good idea, doesn’t it? point source n all (vd not a concern)....

I am sure this goofy triangle made all the rounds with the youtube reviewer promo club (the new apparently exciting kid on the block) and made a bunch of guys hop on it. 

And you got your degree in acoustical engineering where?

I appreciate all the help. I did some mathematical calculation to figure out the angle tilt figured out I need a 3 deg angle at a distance of 5 ft. This correlates to a 3 inch increase at the listening position. Will see how this works out.

Um maybe this one? A2 + B2 = C2 (pythagorean theorem). You would need the √C to find the hypotenuse. Provided you’re looking at a perfect isosceles triangle otherwise it would require a few more calculations.

you use a pile of cds or books under the front edge to find what works, then make something
