Magnepan MG-20 attenuation & tips

So is there any risk to the tweeter if i use 12 wattage ?

As for value, can I go up like to 3 ohms or more without any risk ?

I doubt that there is much additional risk from 12 watts vs. 10 watts -- a resistor will not protect your tweeter like a fuse in any case. If the problem was that you were sending too much power, the resistor would probably pass more than its rated maximum watts for long enough before failing to damage you tweeter.

You could go to 3 ohms resistance or virtually any value without harming your speaker.

May i ask if i want to put sound absorbing panels at the first reflection points on the side walls, what the most suitable materials or brand for MG-20 ?

Can I use curtains or normal fabric?
