I've got here some speakers which were rebuilt from Forsman D2-10 original speakers.
The speakers are NEO 10 NEO 3 and two SEAS CA26RE/P H1562-08
I wanted first to change wiring, but now I'm thinking what crossovers might be not good(cheap), and maybe I should change or upgrade it first.
I just want to ask experts some advice how to better make upgrade and worth it or not. I can't pay 1200 euro for a pair of crossovers which were offered to me here in Germany_ but believe I could make something by myself to improve it, because these speakers have big potential.

Welcome to the forum!
Changing crossover components can either improve the sound or make it worse.
Often it is best to stick to the designer's choice of component type.
For example, it would be easy to say change the bipolar electrolytic capacitors to polypropylene film types but, in practice, the result would be unpredictable.

The wiring looks more than adequate for the job as there is negligible resistance in such a short length of that wire gauge.
I should have started by asking, "What is it you are unhappy about regarding the sound of your loudspeakers?"
You could spend a lot of money on exotic components and connecting wire, after which you will surely convince yourself that there has been an improvement.
However, without proper subjective measurement before and after, you could never be absolutely sure that your perceived improvement is real.
yes. you are right.... Is it possible to measure something in home without professional equipment?
I just see these 2.5mm cheap wiring made pre owner and understand what this is isn't right at all.
You call the wiring cheap, but what are you looking for in more expensive wire?
If by more expensive you mean thicker, then you run the risk of damaging the circuit board and/or speaker connections when fitting it.
It is my old school opinion that changing the wire will result in no sonic benefit.

By changing the wire you will gain exactly nothing. And indeed it is very easy to damage the Neo10 and Neo3 beyond repair by soldering. The manufacturer explicitely recommends to use cable lugs for a reason! If you coincidentally live in Hamburg or nearby I could help you regarding taking measurements.

I want at least OFC or OCC copper, not this cheap bulk cable.
I don't think so. I could say the same by changing speakers cable also, but these affects much more, especially on these sensitive speakers.
I know what there is a risk to damage, but I should take this risk at list ones...

Just a reply on my own experience with crossovers and these neo 10 midrange and seas bass driver. (As a background I also owned BG radia R500 in the past which had M-T-M configuration also using neo 10 and Neo3) the crossover matters more than the cable is the bottom line from my own experience at least. Do you have a diagram or the crossover and parts or can ask the manufacture for one.
the Neo 10 is great, neo 3 too. For my own custom I’m using 2 neo 10 and one Mumforf AMT in mid tweeter mid. I had an audio engineer measure and design the crossover, for a basis which I then added bypass caps too the mid and treble. It was worth the money but I needed to start from scratch and I didn’t have the experience or tools to meatier properly. you are using the original crossover designed for those drivers someone already did the basis work for you. Yes poly may sound different if you replace caps but trying changing the caps and resistors if you don’t mind soldering could be a good start. You can always put them back or go on to adjust it further.

Nice speakers. Professional design and great looks. Not like mine, which are ugly but good working. I would use neo10 as dipole, not sure why its closed back.
Thank you, Daniel, for sharing your experience! How much did you pay for crossovers? Do you think just changing caps could make a big difference?
Distance to back wall was a consideration, changing the Collin would allow for a change in the future to be dipole for the neo10 too, I am tempted but also then crossover will need adjusting most likely.
DM coming, parts cost depends on what type you go for, you have 4 caps per crossover from what I can see, if you can work out the layout or get a diagram from online or the company that made them you might try the caps for mid and treble. I can’t say for sure the impact but I’d be tempted to change the caps before any cable. There is tons of advice on caps on this forum, but also here: remember if you change something burn it time can be long.
