tomp,
When I had my MGIIB's in the '80s it was fascinating to watch the fuse element physically move inside the glass tube. This was at higher volume listening levels, but not as loud as one would think.
Physically constraining the fuse element by damping might be interesting. I know after some period of time, the MGIIB speakers would not sound as good even with periodic cleaning of the contacts. Replacing the fuse restored the sound quality.
This will be an interesting trial.
In the mean time, my room has new drywall installed, the walls painted and floor installed. Sounds like a giant echo chamber.
Talked to SonitusUSA and asked about if they had east coast installers for the Ultra Package for my room. Waiting on response. I did get copies of the material specs to review.
I also talked to Bay Acoustics in Baltimore and they are sending an estimate to measure the room acoustics of the room for a 3D model to suggest an appropriate acoustic installation for my listening room. Waiting on that now.
One step at a time.
A typical AGC 3 amp fuse has a resistance of 0.045 ohms. Even if the resistance rose to 1 ohm the fuse would blow at 0.3A which represents 1/3W into 4 ohms. Hard to determine the mechanism that could cause an audible change.
