Volt BM228.8 Tweeter pairing (Two-Way)

Hey everybody,

Over the last few weeks i've finaly been taking my first steps into making my own loudspeakers.
First project has been a crazy setup for a 16 channel sound installation, where i got to design all loudspeakers.
Notably where these coaxial SB Acoustics 5" and 6" variants, but maybe more on this another time.

Long story short: Great experience to built something, now let's find out what we can achieve with a little more budget.
The plan is to build a set of small studio monitors using the Volt BM228.8 woofers and i'm looking for a good pair of tweeters to go with them.
All will be powered and filtered by a Hypex FA123 (using two channels bridged to drive the woofer).

On the short list so far are:
Scan-Speak D2905-990000 (Have been used in this configuration before, as i found out)
blieSMa T34A-4

Both tweeter should be able to go low enough to cross them around 1.6; matching the Volt.
So here's the main question: Does anybody know any other tweeters to look at?
Any general advice about my plans are also quite welcome as well!

Thanks in advance!

Can't remember, maybe more sensitivity, and 4 ohm (over 6 ohms) so better use of the 100w for tweeter on the FA123. Better high frequency dispersion on the SB maybe too. Also availability too - I can get the SB stuff cheaper and quicker where I live.

I found some of the measurements of the SB with the BM228.8 on my very crowded desktop. Not sure if these were the final or part way through. All the same as far as I remember but with various smoothing applied. Likely 1M on axis from memory.
