I would like to begin and thank all of You for taking time and helping me with this, so: thanks a million!

Earl and Widget: Very good points! I remember looking at those measurements and how many of the drivers weren't up to specs. I will let a friend of mine who is a certified JBL repairguy have a look at them. Before this, I used the ME150's together with my 2450's and 2405 in a passive setup, and the ME150 doesn't sound as good in the new setup. That is why I still think the M552 is the source of evil . To be more precise it was like someone pulled down a curtain in front of the speakers. The dynamics, realism and timbre disappeared.


Rob: I think You gave a good advice: to look into a 9800 network and try to remake it into a 2-way. But it isn't easy and I haven't got a clue where to begin . My friend the repairguy can fix any driver but isn't a crossover constructor. I guess I have some studying to do!

I'm beginning to understand how lucky I was when I used the N333 network with drivers and horns it were not designed for and got very good results (well I thought they sonded nice, they probably measured like a bose from hell ). Had a thought that this would be even easier but I guess I've learned that there is a lot more to building speakers than throw together some drivers and connect them to a network. Greg Timbers and all the other constructers at JBL have my deepest respect. At least, THEY know what they are doing

Would using the NS3100 be a complete disaster? I guess the 2435 is far from the 2426 specswise. Guido gave me the advice to use the NS3100 for the LF and build something like the 4430 for the HF. A bit puzzled about that since they cross their drivers at different frequencies, 750 vs 1000Hz. If You read this Guido, would You mind explaining a bit more?



Thanks all!
