As an owner of a pair of Magnaplaner model SMG-C's I would like to make a suggestion.
In less than a week after purchase the left channel Hi Freq. section burned out.
Turned out that the Audio retailer had replaced the 4 amp fuse with a slo blow version.
Fortunately, the factory took responsibility and re-built at no cost to me.
In your post I see no indication of any current sensing protection.
To determine what value fuse would be needed you might attach a thermocouple temp sensor with tape to the Mylar, inject a 100 hz sine-wave through a current meter into the panel and gradually increase the amplitude until the temp begins to increase and note the current at that point. Installing a fuse with a value about 20% lower than the max. current read under test should protect your panels.

that is a good idea, but for now im looking for the right sound and a good manner to produce the same panels over and over.

im trying to make one big mid high panel, and wil post pictures of procces so everybody can take a look. and maybe have suggestions.


the previous pannels i used with a woofer of 87 db with active crossove, both panels on each side in series, has around 3.3 Ogm DC wich will roughly be 3.3 x 1.3 4.3 ohm so around the 4.
they if want to let them blend with my woofers i have to put them back 4 dB so that means efficiency is quit good.

Looks like a 2m long section may be possible!

I would very much like to build my own ribbon!

I must investigate my local hardware store!
