Magnepan .7 vs 1.7 tech question?


Two questions,

 

1. Hopefully someone can help. Does anyone know if a change of fuse to a Magnepan .7 and 1.7 can be placed in order to add more sparkle/treble to the top end? The fuses that come with them appear to do the opposite. Is this possible?

 

2. I’ve heard a couple of rumors that the 1.7 needs more power/current than the .7 yet the specs of 86db efficiency and 4 ohm load are the same. Opinions greatly appreciated.

I had always thought it was the resistor that cut some of the high end. I've never had a problem with 1.7, 1.7i or 3.7i on the tip end. I have alternated between wire and resistors as a jumper which will change the top end .

You do need an amp with plenty of power and available output amperage.

Hope that helps.

Happy Holidays

bdp24 has it 100% correct.

I hope you meant to type incorrect.

!.7s and newer are all quasi ribbons, except for the 3, 20, and 30 series, which are true ribbons.

The Magnepan magnetic-planar drivers have wire conductors glued onto the mylar diaphram.

You are right the new models don't have wires glued to the mylar anymore, it's a printed circuit now. You might call the panels all quasi-ribbons now but due to history of those particular loudspeakers you still can call them planer-magnetic and not be wrong.
