Blown Tweeter & midrange fuses Magnepan 3.6r

My problem is I keep blowing the tweeter fuses at a "somewhat" moderate volume. I inititially owned the Yamaha RV-1103 Surround Receiver and blew both the tweeter fuses at somewhere around 2/3 - 3/4 volume potentiometer setting. I heard that these speakers require a lot of high current. Many people drive these with 40 wpc mono-blocks in a good size room and don't complain of blown fuses.

I purchased a Krell HEAT (Showcase) system (125 wpc @ 8 ohm, doubling to 250 wpc a (Magnepan rated) 4 ohm load. I still have the same problem. In fact I have even blown the 5amp midrange fuses. The maximum power level on the Krell digital amplifier is 100). I set the level at 40 and still blow the tweeter fuses in both channels simultaneously. I have never heard any audible cliipping during these times, however, my hearing rolls off at 14 KHZ. I have had two different KRELL HEAT (Showcase) amplifiers driving them, with same results. I have an open floor plan 20' x 15' listening area and the volume levels are no where near ear-piercing levels. I'm beginning to think I purchased defective speakers. Can you help me?
What do you think ?

HELLO,

PLEASE LET ME KNOW THE RIGHT TYPE (AGC, ACG, ETC) OF FUSES REGARDING MAGNEPAN 3.6.
ALSO, IN THE MANUAL IS WRITTEN THAT THE FUSE FOR LOW IS 4 AMP BUT ON THE BACK OF THE SPEAKERS SHOWS 5 AMPS.
THEN WHICH IS CORRECTED!!

THANKS IN ADVANCE

ALL THE BEST

Hey Sangel,
I have Magnepan 3.6s also. Had them about 3 years. I owned 2.5s before these and had the 2.5s about 12 years. I occasionally would blow a fuse with the 2.5s a few years ago. I am now using Krell ksa 250s biamped and have never blown the fuses on the 3.6s. I too like to listen to music at loud volumes. Sometimes hard rock like Korn, Foo Fighters, etc and it frustrates me when I remember my Cerwin Vega d9s from high school that had an spl of max 125. Of course, they did not sound as good as a magnepan or a Martin Logan. I am wondering if the Martin Logans play louder than maggies without sounding harsh??

Just cranked up a pair of 3.7i with magtech mono blocks (1000w per channel). at 0db, all the fuses blew.
