Having had a quick read-up online, it seems they should come with their own specific EQ. Because of their design type (6th order bandpass), you risk damaging the bass drivers if used without their appropriate EQ unit which stops all sounds below a certain frequency from getting to the bass driver.
As far as suitability with the 6000 quad goes, the amp itself should be fine as bandpass speakers tend to be incredibly efficient, meaning you don't have to give them much power in order to kick out a fair amount of sound, and are generally very well behaved in terms of impedance. However, your amplifier will need an EQ loop-through, and not knowing the 6000 quad at all in person, couldn't tell you if it has the right connections to run the EQ which you need with your EVs...
