Please advise me what's best amplifier for JBL 4350A? Biamp?
What's for Low Frequency and what's for High?
Can I use Crown VFX2A for external crossover?
Or other: What's best solution?
Many thanks for all ideas!

Nice speakers! Biamp them with a pair of Crown Macro Reference and call it a day:D.

"Best" is a rather subjective term. There are many choices out there, just feed them with the adequate quality power they deserve.

does it have to be 240/50 ? or do you use a converter ?

I used this combination (Series II) for some time and now have the PS400/PS200 combination with Ashly XR1001 crossover and it works very well on my 4345s. Can't say that I've tried many others but I find the amps' input attenuators invaluable. I have several VFX2As but I'm comfortable with the Ashly and they can be had for $100. I'm saving the Crowns for bi-amping my 030s. ;)

I`m liking your Old School suggestions:). One must consider the household voltages and frequency available also.
I`m pretty sure the Crowns can be rewired to accomodate a variety of scenarios, not certain about the Phase Linears however.

Hi,
For the modern system, I used MC2 AUDIO amplifiers and ELECTROVOICE DX46 active crossover.

I finally used:
Crown VFX2A cut at 250 hz
Crown DC300A for low frequency
Tube amp for high frequency (Revox stereo 40)

I cannot satisfy with original horn of 4350 so I move to external horn JBL 2350, but still use origin crossover.
Sound stage so good and very detail now. Very large!

Thanks for your all ideas!
