What type of System would this one be? Vote in Poll. A Full Range System going to a two way Powered Speaker/Tops and also to a Sub which has an onboard bypass filter?
What Type Of System Is This? (The Real Poll)

If there are drivers handling 3 different frequency bands, it is an overall 3-way system, regardless as to how it gets there.
Still a 3-way. There will always be some overlap of frequency handling in drivers, otherwise you'd have holes in the overall frequency response. If the powered tops are run full-range, they still won't cover the spectrum handled by the sub's lower range (unless you have a big woofer in the top and a small one in the sub). Ideally, you'd want to high-pass the tops and low-pass the subs so there is minimal overlap below say 100 HZ, but even if not, it's a 3-way.
Don't complicate things with "Ifs". I laid it out very simple. I see lots of DJs with setups exactly like this one. Dual Full Range going out from Mixer Via a pair of Y Cables from Mixer's Main Output or Main Output and Booth's.
Can you give us a diagram professor...?
You're asking an ambiguous question, without giving details of how it's all connected...

It IS a 3-way system. The ifs are because you did not mention if there were any switches thrown on the speakers. The QSC K-series, for example, have selectable low-cut switches on the tops to minimize issues with a sub (subs are high-cut automatically). Other speakers have similar capabilities. It is also possible to switch things to make them sound worse.
I have no doubt someone can make any system sound like crap if they wanted to.
Steve it is a two way Powered Speaker being fed a Full Rang Signal Period, no switches to be thrown or nothing to adjust. Bass Cabinet gets the same Full Range signal and filters it at 100HZ
2 way system. If you have no way of controlling the Hi's, Mids and Sub frequencies on an individual basis...(not talking mixer eq either) then its a 2 way system in theory
Guess I'm not sure where you were hoping this would go ... Just because the tops GET a full range signal, doesn't mean they process a full-range signal, especially a powered speaker that has on-board DSP. As Rick said, there isn't enough info. The sub would handle a certain limited part of the spectrum. The tops will be limited at the bottom end by the size of the driver (not mentioned). So even without an overall crossover, it is still 3-way. Is it the BEST way to hook them up? Probably not, unless, as I mentioned, your speakers have high/low pass/cut capability in them, like many active DSP controlled units do. Is an external crossover better, not always, though it gives some flexibility and the ability to control settings without running over to a speaker.
If I feed a full-range signal to a piezo tweeter and a full-range signal to a 12" woofer in the same box (many piezo based systems did not use a crossover), it is still a 2-way.

You don't have the ability to control things in a 2-way non-biampable passive top and it's still 2-way.
Again read carefully. A Full Range Signal going in to a Two Way Speaker Cabinet does get processed! It becomes a Two Way System in THAT Cabinet!
AND .. with a sub getting a processed full-range signal, the overall system becomes a 3-way. I did not say that the tops weren't 2-way .. they are.
Ok then explain your findings. I won't ask specific questions to give away the answers correct or incorrect. What is a three way system and how does you answer in THIS case, fit in to that protocol?
It is apparent that all of this is because you heard a shi**y sounding top-over-sub setup. I can make your 802s-over-scoops sound bad too. It may be that the speakers used DID NOT have the ability to set switches to allow the cabinets to behave as if they were cross-over'd properly, you didn't specify, so we don't know. If they did not, there should have been an external x-over/driverack to do that. But there are plenty of sub/top combinations that have the ability to limit the frequencies being process inside that cabinet without an external x-over .. and some have more than basic controls .. it depends on the models used.
My JBL PRX tops do not have a low cut filter, but the subs DO have a high pass filter on the outputs, so if you send a full-range signal to the sub, then daisy chain to the top, the top will only get a signal above 90HZ.

A multi-way (2,3,4) system uses multiple drivers focused on different parts of the frequency spectrum. It does not REQUIRE a cross-over to be multi-way, though a cross-over certainly helps in controlling sound.
I don't know what more you're looking for .. the scenario you laid out (poll) is a 3-way system. Is there a specific issue you have?

LOL no specific issue. By the way, i have been meaning to post this poll for a very long time now. You want me to give you more detail...ok here goes. The Two Way tops have no other outputs or switches, just one input ok. The sub has no other outputs or switches just a bypass filter to cut off everything above 100hz. OK now there you are for this specific scenario.
