A friend of mine who taught me a lot of what I know has a lot of weird techniques, many of them are very interesting and very effective in practice.
I was wondering if anyone has seen this done or tried it themselves.
Basically he unwinds the crossover coil a bit and solders to the driver, taking out the contact points, so he has one wire and one coil end, both hardwired to the driver.
The speakers he's finished over the years (the few that he's decided are complete that is!) do sound stunning.
Bypassing all inputs and hardwiring into the voume pot on some amps is another thing that seems to really work well.
So has anyone come across this coil tweak?

There are those who connect crossover components to each other using only their own lead-in wires and employing no 'nasty' additional wiring. The components are simply plastic tied to a wooden board.
If close enough to a driver, an inductor lead-in wire could be used to connect directly to the driver.
However, it wouldn't do to unwind too much wire from the inductor to stretch a long distance to the driver as this would reduce its inductance!

Will have to have a look, I think he reassembles the crossover and brings it closer, how many turns would be too much to unwind roughly?
Impossible to say in regard to number of turns.
What you would do is measure the inductance with a suitable multimeter and make sure you reduce it by no more than, say, a couple of percent.
Alternatively, you buy an inductor of a higher inductance than necessary then unwind it to the required inductance.
> how many turns
Taking off 1% of the turns makes 2% less inductance. Most Xover work is not this precise; but some is. So if it looks like about 100 turns, 1 turn may be a wise limit.
I don't think a short length of ample wire with perfect joints makes any difference.
I am inclined to think that *some* craftspersons have "magic in their hands".

I assume these are air cores he is putting so close to the magnet. I would be concerned about vibration breaking the single conductor.
That's a good point - the standard method of PCB mount crossover components with shake-proof spade-terminals is tried and tested.
