Magnepan Owners

I have the upgrade kit in my 1.7is. It works!  Running the highs (tweeter) thru that little glass tinned wire fuse has to impede resolution.  Just be careful, they are wide open with the fuse delete, driving them with an underpowered amp into distortion could end badly..

Hi Guys , thought I would weigh in quickly as I am the mod designer. As a point of reference I would not own nor use Magnepan in stock form, and soon I will have essentially removed the big panel and ribbon tweeter from what were new 3.7i, and chucked everything else. This was done more as an exercise than anything to see where we can go with these speakers, and what mods or experience I could pass on to my brother Maggie lovers. Ive used Maggie over 10 years, never using a fuse ever. Let me start by asking the readers, Ccn anybody reading this thread attest to a blown fuse ? Ive never even heard of it much less seen it. As a matter of fact, if you would like to see a 3.7i playing at over 90Db without even breaking a sweat then check out these vids I posted to the net.

Your concern is distortion not the fuse. My rig is low distortion, therefore smooth sailing. Bdp24 is right that whole fuse contraption degrades signal. The simple mod I posted as "instant" is exactly that. for people that just don’t want to tear in to their new Maggies. I’m one of those crazies that in the pursuit of knowledge will strip a new 3.7i bare to learn about it. Then I can offer mods or feedback on the nature of Magnepan as seen through the eyes of an OCD AudioFoil manufacturer and designer. These speakers are greatly misunderstood and Maggie keeps tight lips about what their real nature is most likely to keep an unbiased position on how to listen, or what to use, etc. First truth : Maggies are mid/high optimized. This means they will reproduce low frequency, sure, but removing low frequency from the Mag, and putting it to a sub, even in the case of 20 series, will exponentially increase your sonic experience. Finally the mids and highs are unimpeded by low freq vibration. I dont mean just adding subs, I mean high passing the Mags to REMOVE 80-90Hz and below. (with a slope of course) along with the subs. You will not believe the improvement it makes. Soon we be releasing an integrated stand with powered subwoofer so you will need no more floor space than you do now, and be able to add a sub and reap the benefits of bi amping and actively crossing over your Mags.

all the best and happy listening !

Probably won't make that much of a difference compared with completely rewiring the speakers with various gauges of OFC cryoed copper wire, using copper binding posts, bypassing the fuses, upgrading the stands buying Mye's, and then building an entirely new external crossover out of very high quality parts. 

Any of these things, especially the speaker stands, might be a better option. Bypassing the fuses is not to be done if you drive the speakers hard.

Hi Barry, only partially true. If you drive your amps into distortion you should say.. To prove my point you can watch me drive the 3.7i to a limit as high as a live rock concert using Jeff Rowland monos known for their low distortion, The link is in my above post. You have no idea how far you can push Mags, I didnt. But I was willing to to find out. These are truly world class performers in a "dumbed down" (for lack of a better term) guise. No matter the level I bring the rig the Maggies hang with me and do not disappoint. Youll see in the videos there is no lack of dynamics in a Magnepan. One just needs to understand them and set them up properly to do what I'm doing in the videos. 

Cheers !

I've blown a fuse in my Magnepans before, so be careful bypassing the fuses.
