Q about placing tweeter below midbass

It's not really necessary; though mine are tilted slightly due to how close I am to them (small room).

The important thing is to get the offset right when designing your crossover. Get a tape measure and measure from the listening position. That will give you the correct offset for each driver.

In the past, tweeter below the midwoofer was done on a lot of speakers that used BW1 (norm polarity) and BW3 (rev polarity) to compensate for the downward polar tilt (approx -15°). Reversing the drivers can give an approx +15° tilt if offsets have been taken into account. This gives a ZDP (zero delay plane) close to 0°.

Hardly ever see it these days.
