I have placed an order for a pair of 1.7s. I want to upgrade the fuses but I don't know what spec is shown on the back place for the fuse. One person thought the spec was for a 4amp but I thought that seemed high. Could someone please let me know what the amp size it is. I assume it's a fast blow. Any help would be appreciated.
And you're doing this because Magnepan doesn't know what they're doing when they spec the fuses for their speakers? Spend your money on better source matl., it will pay off much more handsomely...
5560, I found upgrading fuses on my 3.7's from stock to Audio Magic LA fuses was well worth it. I can't tell you what amperage the 1.7 uses. I would wait until you get the speakers at which point you will be able to tell what amperage to replace them with. They will be fast blo fuses. I also found getting rid of those nasty stock jumpers to be very worthwile. Both of these tweeks resulted in an immediately noticable reduction in grain.
The terminal plate states a maximum fuse value of 4 amps Type 3AG ("normal" or "fast blow"). The bass section does not require fusing protection. This fuse value should never be increased or bypassed. Do not use slow-blow fuses. BURNED OUT TWEETERS ARE NOT COVERED UNDER THE WARRANTY.
I've heard first hand how the HiFi Tuning Fuse improve the Magnepans, the best improvement one can make to the speakers for the least dollars. Its good to have the correct fuse value now, thanks. Empirical Design Jumpers are new to me, really interesting, I'll have research this.
Don_c55 - one should NEVER tell someone to bypass the fuses on these speakers without knowing the full story. The tweeter(s) will fry anytime that the amplifier clips and not knowing the amp being used or the listening levels, the best though on this should be"run your speakers and amplifier for 6 months and if the fuse never blows, you MIGHT consider by-passing it for even greater performance gains."
Just added 4 jumpers from Karl at Empirical Design to my 3.7's. Have listened about 10 hours worth. I'm hearing a little more pronounced midrange and a bit smoother highend. Nothing earth shattering but definitely a change. He also mentioned that if I was interested in another tweak that I should look into the Supreme HiFi fuses.
The back of the panel is a 3AG Fuse 4amp. One recommendation I can suggest to you is the Furutech TF-4A (32mm), would be a great upgrade from that. We sell them if you are interested.
