Default Mods to Maggies

The preceding comments are interesting, including those TSU made about Peter Gunn's work. I was reading earlier today with great interest some comments DAVEY made on another site about the series crossovers Magnepan uses.

But, after spending about 3 hours so far today, I cannot find anything that would tell me how to modify my .7's. Not the 1.7, the .7

I don't believe I'm hijacking this thread, because many people are interested in modifying these smaller Maggies. I just happen to have a good electronic crossover, and would like to try bi-amping my.7. That series crossover confuses me. Davey, can you help?

Anyone?

I've never heard a "Gunned" Magnepan, so cannot make any worth while comments about it. His work is certainly beautiful.

I would contact Mr Gunn....thought the Magnstan site...he well tell you what you can do to get the best out of your spekers...I don't think he like the new .7....I don't know why...but if I owned .7 I would wont to get his feed back....then I would play the .7 in my room...my home....an it thay sound good to me...that would be that...
I guess I am diff than most...but I don't think one pr of any speakers can make me happy..... all the time..
I have a lot of speakers....but I live alone...have a sound room...an I can have what I wont...but I get the Diy thing... an do some my self...but the .7 are new...an the series crossovers is the best sounding passive...but it all about what you wont....
post pic of the crossover an the panels wires input...an we here well give input...help any way we can....

The .7 speaker can bi-amped just like all the Maggie models. I haven't seen a crossover schematic for the .7 so can't analyze it to establish a set of baseline curves to work from, but I imagine it's very similar to the MMGi.

The steps to bi-amp a Magnepan speaker are always the same, in my opinion. Establish exactly what the electrical transfer functions are to each driver using the stock crossover. Then remove/disable the passive crossover and recreate an active crossover with the same curves. You can then adjust/tweak from that point.....if you so choose.

Dave.
