Yes this is mark from iration steppas ! We use Klementz efx box & this is one of the new generations of Electronics builders & we recommend this french men as good new technicians for our soundsystem future for all 👍

I have a stereo filter developed and built by Klem. Nothing to say about the audio qualities of the product. It’s perfect to seek the frequencies and add the sound system touch to our new setup without denaturing the music

Thank you Klementz for the quality of manufacture and the follow-up after sale.
