it is pretty simple and seems to work fine,maybe not highest end🙂 but for such a cheap project i think it's worth of money and effort
anyone build this?

Full-range drivers seem to be favorite in dipole arrangements.

My latest project was high-SPL PA dipoles for treble use using 5" full-rangers. Unfortunately, their treble response isn't any better than the famous Radio Shack 8" full-range! (No whizzer, I guess)

I find that by turning the treble knob all the way up and the 500hz mid to -6, I can get pretty good sound out of mine... pictures later.

Full-range drivers are fantastic.

Haven't heard it or heard one similar to it.

Dependant on where it was to be used

I would think about it for a while before committing to a design that had a tweeter underneath configuration.

It seems that high pitched sounds emanating from below the height or plane of ear level frequently come across as un- natural.

While I enjoy seeing and hearing innovative designs, this tweeter level thing is something that I don't believe I would want to be in the forefront of.

PS if you do build it come back and let us know what you think -

It seems that high pitched sounds emanating from below the height or plane of ear level frequently come across as un- natural.

Tweeters are used below drivers to tilt the polar response
up at crossover, due to the relative offsets of the drivers.

With a piezo horn, with its large offset it should be used above.

I'd suggest checking out baffle step correction circuits for such
a design, the builder appears to be unaware of the problem.

If BSDC is included it also gives an easy way of boosting
treble with circuit modifications rather than an additional driver.

I know this Monacor SP-200X quite well.
It's a shame to use it with such a cheap tweeter!
Also it works very good in closed box.
It also works fine in very wide open baffle,getting rid of the coloration of the box.
