Using the pictures and specifications from the website, I "think" the drivers are:
Scan Speak R2904 http://www.scan-speak.dk/datasheet/r2904_700009.htm
Scan Speak 15M http://www.scan-speak.dk/datasheet/15m_4831g00.htm
Scan Speak 18W http://www.scan-speak.dk/datasheet/18w_8531g00.htm
I know the tweeter uses a different phase plug and the all drivers have some minor custom modifications, but really the stock drivers would be pretty close.
Using the same cabinet dimensions 1120 x 350 x 565 mm (HxWxD).
For the crossover the DEQX PDC-2.6 HD processor / active crossover http://www.deqx.com/products3.php
What you guys think? Can it be done?
Would land up with a pretty accurate cremona clone yeah?

the tweeter is a vifa xt25, as far as I know

Parts Express has an XT25 buyout tweeter that may interest you:

Wrong phase plug, but right mounting plate.

An externally hosted image should be here but it was not working when we last tested it.

You would be better of with a Marchand XM-44,

Incredible performance, I used them with $11K Shahinian Hawks, so don't think this isn't a good product. Those DEOX processors are very expensive, you would also be better of buying a used pair of Cremona's off of Audiogon.
I'm also a hobbyist, and have been building high-end for 17 years, and have used Marchand crossovers for many projects.

How do you measure to find out the best crossover points? The DEQX comes with the mic and software etc.
You need to start with some good simulation software. What you are trying to do will take some real work.
You need to start reading books from the library on the speaker building. Then you needs some good software (Lspcad, Leap, ect), or you can pay someone to design the crossover, but that will not get you the results you need unless you hired a professional. Some of the driver retailers do crossover design, but the cremona has a very, very well designed filter network in it.
Take a look at a pro-hobbyist like Troels:

Read everything you can here, and then go to the library, there are some great books.
