The 1'' baffle space optimises the smooth crossover transition at 1k Hertz.

Agreed. If measured from the correct listening height.

My point was that since the L200 cabinet has a sloped baffle it changes the relative distance between woofer acoustic center and HF acoustic center.

Come on Ian, keep up.

BTW how is the crossover coming?

The 443X are designed for a 15 degree upward tilt on verticval polar axis for inverted mounting, according to my rather dog eared white paper.

Zilch, some tweeking will be needed and access to a gated test set to result in the smoothest transition in the crossover region. The JBL network was optimised for that driver layout only.

Regards the tilted baffle why not if you wish, the design is supposed to give even power response on a 100 degree arch.

The biamping can be done with other than the 5234/5 JBL networks if you like bi amping but be prepared to fiddle a bit. If you use the JBL passives it would be a good place to start imho
.

Either way it will be vastly superior to the L200 combination.

You are in for a treat.

PS. The Widget or John F should start carving Bum horns, and if theres a demand I will make a hi fi crossover and mini class A amp for the 2426/2344 and retire..LOL
