Housing construction for satellites !

Hi guys! Is a bit offtopic but I’m sure you know each other well I bought 2 ways tweeter for the front of my Twingo Hertz ECX 87. Unfortunately, these sounds simply crappy, but were relatively expensive for the size ( 50€ ). Now I wonder if I could come here with a housing on a decent performance, since I don’t need them for the car anymore, but at home 2 out of 6 satellites are still relatively bad. And the Hertz owns h should be much better. So 2 questions Can you do a lot ? And what dimensions would you recommend for these boxes ? ( housing ) Data : Total depth : 46mm Installation depth : 35 mm mounting hole diameter ? : 80 mm magnet size : 60 mm voice coil diameter : 20 mm Thanks in advance for your information mfg. Kepnik
