Speaker height...should known better

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

Experimenting with speaker position is the single most overlooked issue in system set up- in consumer and pro.  For those with excellent hearing, even a few degrees off axis (off angle to the spot the speakers sound best) is audible.  For example, setting speakers sideways is an awful idea as the frequency area where the tweeter and woofer combine ALWAYS narrows vertical dispersion when the tweeter is above the woofer.  Ths works out okay when the speaker is set vertically.  Set horizontally, you narrow the dispersion dramatically in the horizontal plane, making the the sweet spot much smaller and increasing the energy going above and below the horizontal speaker.  If you could see the dispersion, the area where you can hear the speaker correctly in a vertical speaker now set up to be a horizontal speaker increases unwanted reflections. 

A good rule in proper speaker design is the tweeter above the midrange, midrange above the bass driver.  Its where the drivers combine (at crossover points) that the dispersion of the speaker is determined.
