Was looking for anyone thats heard the 1" smc225/ND i was thinking of using these in a project i have heard the cp380 is used as a tweeter in the Avantgarde trio if thats true that says a lot about the upper octaves of the cp380. So witch Beyma 1" driver do you like for clean high frequency's ???
Have you selected a horn/waveguide?
Have you selected a crossover frequency & slope?
The CP380n is sometimes selected because it's plastic 44mm diaphragm allows a low ~1.1kHz crossover, and it has low harmonic distortion for its price. A good crossover can lift the 18kHz without concern for nasty distortion seen on several metal domes. The CP380n weights 7.2 pounds, and some old school engineers quote Newton's laws on equal and opposite forces help smooth transients.
From the datasheets the CP380n appears to have lower harmonic distortion than the SMC-225Nd.

The question you're asking is not going to help you as much as you think. A driver that has worked well on one particular horn might be a lesser choice on another. Ideally what you want to do is pick a number of good candidates and test them all. Or at the very least try one and be prepared that it might not be the final choice. This is especially true where a passive crossover is involved.
Beyma compression drivers
I am going to use one of the two models as a tweeter in a 3 way horn i have a small elliptical waveguide with a 3500khz minimum crossover point and it will be crossed over at 7000khz. 18db slope. I know a lot of people would use a dedicated tweeter but i have never really heard a tweeter i really liked. Plus the 225/ND are only $225.00 a pair from Loudspeakerfreaks.com and thats with shipping the cp380 would be about $245.00.

for your application I would suggest to use Faital Pro HF108 on a Faital Pro STH100 elliptical horn or 18sound XT120 elliptical horn. this combination is really hard to beat for +5khz. you won't find a better-sounding horn speaker in this price range. I've had many of other CD and horns in that price but HF108 with elliptic horn sounds best of all
Dave123 how wide is despersion on this Faital combo is it almost like a dome tweeter or is the dipersion of sound very narrow. i have a deep 400Hz tractrix horn for 1" compressiondriver, and it is very directional.
For a 7,000Hz crossover frequency, an integrated horn-tweeter (super tweeter) is a popular choice. Fostex stand-alone T90A ($190), and on-baffle FT96H ($140) are popular. Beyma CP22. B&C DE35. ... several others... If you favor a separate horn of a certain polar pattern, there are 0.5" and 0.75" diameter dome compression drivers which easily produce a clean 20Khz, plus several matching horns available.
Probablly worth some of research before you purchase.
The HF108 is a annular phase plug the HF108R is a radial phase plug the HF108R starts to drop high frequency after 10K the HF108 dose not. Faital needs to update their info their website says the HF108R is annular phase that info is wrong. You will see the same exact Faital drivers but with annular or radial plugs and the annular always have the smoothest upper octaves i always stay away from radial phase plug drivers for this very reason.
I have heard fostex before and was not impressed all price no performance also don't like the Beyma cp21 or 22 or 25 i have heard a lot of tweeters silk dome, horn tweeters and ribbons and never liked any. I have heard a couple 1" compression drivers i liked TAD 2001 & radian 475pb sound sweet very dynamic and well real sounding but both have aluminum diaphragms witch tend to fatigue my ears after a while thats why i am looking for opinions on the Beyma's they have a poyester & mylar diaphragms that are not fatiguing.
