I have a pair of Italian Opera Mini speakers that are 20 years old. And decided I still like them and wanted to give them a big update for the next 20 years...

I bought 2 FaitalPRO 5FE120 (4-ohm) and 2 Dayton Audio AMTPRO-4 AMT tweeters that work from 800Hz! And of course filtered it at 800 Hz.

As a sound engineer I can say, the combination works wonders!

I strongly recommend both the speakers and especially the combination.

exccellent packaging Use as DIY portable boombox, Fb at 65 Hz, Vb- 4 l. Realy loud and clear.
