Outboard crossover? Why not?

Although I have read the thread here re crossovers, I am still bemused by my own situation. I bought for my third system 2 Audiovector (Mi5s I think) speakers that the seller said were not jumpable but needed a 6 channel amp. The Mi5s have 3 sets of inputs and I have since bought more Mi5s of "similar 3 input sets" to have a consistent surround set up. The more recent purchased speakers I saw had been jumped by the previous owners, so now  I wonder about the first set I bought. With the first set the seller included an external crossover box and suggested I bought a Rotel 1066 which he said would be very suitable. I bought a 1066 as they are not expensive and so I now am confused as to how to progress. The external crossover situation seems daft as I would surely need 6 speaker cables for the 2 speakers - best presumably all the same - and that would just look silly going into the rear of the speakers. I do have many speaker cables which I would be pleased to find a use for!

@tatyana69   Internal Crossover,  Correct?  3 pairs of teminals... Bass, mid, treble,  Correct?  For the life of me, I can't see any reason that you couldn't jumper these.... I would assume that the seller just thought they were better being tri-amped, but being passive crossovers, that is not always the case,  You should be able to jump these without issue.... To be fair, I've never laid my hands on a AudioVector speaker,  but I've been in more speakers than I care to think of,  Should be no risk involved at all to jump these.  I hope this helps,  Tim

You have to be SURE that you have an internal crossover! :)

If so, then sure, jumper away.

The tweeter, for instance, needs at least 1 cap to keep it from blowing.

My current reference pair, there's no internal crossover at all, but you can't tell by looking at the outside.

Best,

Erik

Many thanks for all that. It is a price of not really paying attention on a purchase!
As Erik says, the non existence of an internal crossover may not be stated on the back, so what indications can I look for that I have or have not?
Surely jumping can do less damage (Tim thinks so whatever internals??) in any circumstances than triamping, if that is what it is called.? For those who do triamp do they really prefer all those speaker cables?

I am a BIG fan of not using speakers with crossovers inside them.  I use an active crossover (DBX) and it is between my preamp and amps, so my amps actually see my speakers, directly, not my crossover.  When you use internal crossovers, your amps never see the drivers, just the crossover.
