Default Cross over Neo8 PDR and Neo 3 PDR

Does anybody know a good crossover between these units?
Just to give me a quick start, final crossover will be tuned further. I want to use them open baffle.

I'm working on a speaker with a Neo3, two Neo8PDR's and a Scanspeak 25W. Filter middle/high will be passive and low / middle will be active.

I have the wood in house and first parts are glued to getter.

Yep, I'm interested too.
Don't know where but I think I've read somewhere that someone was using the 8 from 400Hz up to 5kHz, where the 3 takes over.

I was think about 600hz 24db active and 5khz -6db passive. First tests looked promissing.

How is the sound of the Neo 3?
I have an very old heavily modified T120 K in the ML-TQWP's, might replace it. But to be honest, i want an all new diy speaker....
Click the image to open in full size.

I have made a quick design with a d'appolito around a dipole radiating Neo 3, and two alu mid bass drivers. A 60 degr. cone on backside of Neo helps radiating the sound through room.
And as you see in avatar, made some 360 degrees radiating tweeters from simple dome's too.

I have currently a Neo8PDR dipole together with a Scanspeak 18W in BR. Crossover at 800hz.

Jeroen, are you thinking about bi-amping the final speaker or didi you use the 4th orde active x-ver just to test the performance of the NEO8?

I'm going to use an amp for low and an amp for mid/high. Low is divided form mid/high via an active -24db Thel filter and mid and high are divided passively.
