Even "active speakers" could be misinterpretted, I can use my speakers as active, but they don't have amps attached to them like
powered speakers do. All active means is that crossovers are applied at signal level and not post-amp.
Sorry to be pedantic
From Wikipedia: Powered speakers (or active speakers) are speakers that have built-in amplifiers.
As to (passive) speaker cables, I'm guilty of expecting everybody to realise that those cables are different to signal cables. Sorry.

Give that man a large medal. Spot on, within pro audio, "active" and "passive" refer to the position of the crossover within the signal chain, and absolutely nothing to do with whether a box is powered or unpowered.
It is one of the most widely misunderstood and misrepresented terminologies, especially at disco/pub band/entry level where manufacturers and retailers alike use the description incorrectly.

I'm not sure I agree, I have a similar view to Peter.
Another example - network hubs can be passive (no built-in power supply) or active. The same principle applies.

Lol its not about agreeing or disgareeing, its fact!
Most powered speakers are infact also active as they have a crossover at signal level before the amp for each driver within the cab, which is where the confusion comes from. But you can of course have an active speaker setup that doesn't involve powered cabinets.

You may be right. What's your reference?

I think there needs to be a distinction made between 'Crossovers', 'Speakers' & 'Systems'.
This is my understanding of the differences:
Active:
An active speaker is one which has built in amplifiers and either an electronic or passive crossover.
An active (or electronic) crossover is one which goes before the amplifiers in the signal path.
Passive:
A passive speaker is one which has no amplifiers and a passive crossover.
A passive crossover is one which goes after the amplifier(s).
System v Speaker
An active system usually has the crossover and amps remotely situated from the speakers.
An active speaker has the crossover and amps situated in the speakers.

It's one of those things that just about everybody gets 'wrong', so in the end it's just as easy to be wrong!
I was told a while ago that active means what Tony is saying, but I still call my system active rather than powered. Mostly anyway.

Interesting.
Does this mean that there are active speakers which are passive, and passive speakers which are active, or have I misunderstood your post, Tony?
Also, how do you find out whether your speakers are genuinely active or passive?
