Drivers appear worthy of using. Could not find any measurements on the yamaha, appears to be suited to a 60 litre sealed cabinet. It would make sense to perform impedance and FR measurements, otherwise guesswork. I had a chance to work on a midrange unit that looked like Saba, was a favor for a buddy and it turned out to be quite an awesome vocal performer. Vintage stuff can do quite a bit if you know how to design crossovers.

Do you have amplifiers?
Thank you for your response..

I don't have any amplifiers, i would like to know what would be ideal for these..

Whatever the case without any measurement gear it will be difficult to do much. Assuming you arenít going to have what you need to measure Thiel small parameters, which you would need to design an appropriate box, I would suggest you look up cheap/easy open baffle designs. Tell us more about what your goals are and maybe youíll get some suggestions.
Thanks you for your response...

I know for sure the quality won't be the best, but I wanted to use the Yamaha for a sub and the two smaller ones for satellites if possible.

Not really suitable for use as satellites. They have tiny voice coils, hence that 3 watt stamp on the back of the magnet. Put 10 watts though them full range and they might last a couple of minutes. I take it you only have one of the woofers? The cost of a capacitor to limit the high frequency getting to the Casio driver might be enough to get slightly better drivers.
I get my cheap drivers by upcycling old All-in-one home theatre sets I pick up by the road or at the tip/dump or friends who would rather buy new than repair
Something very much like those were in my very first computer speakers, driven by a 5 watt stereo chip amplifier and I managed to blow them up in a week

There are many options here, but I think almost anything will do. Something with volume/bass/treble would be useful. Old or new is good.
