Finally I deciced to W200S and W250S in parallel (3,5 way). W200S propably will be closed, A250S in bas-reflex. Just like in Tone Gee 2,5 way
W200S is a nice driver. I've used Visaton alot and like their products, especially the NLA WS line. Make sure you have enough BSC on the driver to linearize phase and amplitude, otherwise it won't blend well with the D7608.
Finally Visaton G50 FFL replaced D7608. D7608 is more difficult to apply and require 1dm3 enclosure.
What is BSC?
Baffle step compensation. The 50FFL will have to cross higher due to diameter and smaller chamber with higher Fs. Will be more challenging to blend with the midbass.
I don't recommend an xover lower than 800 hz 3rd order You may need to use an LCR to get higher SPL from it. The other issue is the ferrofluid. That will hurt low level detail. You could remove it but may cause undesirable behavior around Fs, as Q will likely go up.
The 22W8534 has a fiberglass cone. It will do just fine up to 1k+ and work well with a smaller mid dome. The directivity doesn't get tight until past that 1k+ point, so it will blend fairly well.
