    Best amplifier for JBL 4350?

    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.

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

    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.

    Thanks a lot all!

    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!
    Regards,
