What opinion have you about Morel ET338 for two way project ?
Is any comparison with other domes like Hiquphon , Scan Speak etc

It's a great tweeter, but I think the CAT 308 gets you about 99% of the way there for half the price. Either of them beat the Hiquphon in my opinion and can compete with the SS 2905/9300 or 9500, but don't quite match the 9700 and are bested quite soundly be the 9800 and 9900.

Morel tweeters are in the same high quality league as any other reputable manufacturer. It is a matter of taste and personal preference which one should you acquire. Personally, I would agree with Dan on CAT 308 and use that one for my needs, but if a third party had me to design a high end project, an ET 338 would be in order, for third party peace of mind. Morel replacement voice coil dome assemblies are cheaper than SS.
i love that tweeter (or to be more accurate i love the MDT33 which is basically the same)
As a simple 2 way it would be great but i think that to bring out the best of this tweeter it should be maybe paired with another tweeter or have dome-mid to work with. then its a real treat. (i think dynaudio, which is also similar to morel, thinks the same, look at the top models of dynaudio)

Being that these tweeters have an rms of 200watts, can these be used for pro audio (crossed at around 2.5k)?
It's not 200W rms, it's 200W DIN power. Various industry standards, but mostly people use IEE Pink Noise with a 2.5kHz, 12dB filter. Sounds like rain on a tin roof.
Instantaneous can be quite high, but only for a few milliseconds.
It all gets complicated, but I'd be surprised if any HiFi tweeter can wick away more than 10W rms of heat continuous. Even with ferrofluid. Think how hot a 10W lightbulb gets.
With PA, you use horns to increase efficiency maybe 15dB. 3db being a doubling of power. You add heatsinks to the chassis and use metal formers. Lightbulb current limiters. PA tends to be more 100dB loudness. Even use multiple 4x12" driver arrays to focus sound and lower the power to each driver. Different animals. Have a look at Eminence for the right idea:

Bottom line, this is a 90dB domestic tweeter. Still at risk at parties. But an 0.5-1.0 Amp fuse can help avoid expensive repairs.
