On hold due to other things in my life and the interested customer had a delay as well. Now I am involved with a house move so I doubt it will be before early next year. All the bits are here waiting so it will be done at some point.

BTW they are not active, as active speakers require an active crossover, which I hate. They are passive crossovers with separate power amps, so probably the best description is internally powered speakers.

The whole active vs. passive vs. powered debate has opened up huge cans of worms in some quarters. My take these days is that it's the COMPLETE speaker system that's important.

Anyway, I doubt that NVA passive crossovers would be particularly complex anyway, so not intrusive. Even complex ones can be designed, in conjunction with the drivers used, not to get in the way to any negative extent.

Effectively there is no crossover. Nothing on the bass / mid driver it is filtered mechanically by doping. The tweeter only has capacitor protection from low frequencies not a crossover, and a series padding resistor to equalise the efficiency of the drivers.

Well then, it's active as there's nowt between bass-mid amp and driver. The tweeter has relatively little to do electrically I believe, if not subjectively...

It is not active as if you search the term it applies to active (ie electronic) filters being used to separate the drivers. The ONLY two components in front to the NVA drivers, and only the tweeter, are passive components. The definition of active is to be powered and using active gain devices either transistors, valves or integrated circuit op-amps.
