MiniGrand Saga Part 2

I originally posted pix of my MiniGrand restoration back in August:

Much has gone on since. While cleaning off residual adhesive from one of the frames holding the woofer panel, a small tool fell of the table and crinkled the lower part of the panel:

OUCH!!! I had a crisis on hand. Fortunately I found a pair of Stages in pristine condition near Sacramento. We borrowed our neighbor's minivan and headed to Auburn CA.
We visited several friends and family as well.
I purchased the pair. I swapped out the older Graz ribbon on his pair with the new XLM2's I had purchased.

The speaker to the right is the NOS speaker with the XLM2 ribbon and the North Creek crossover. My rebuild crossover can be seen on the left speaker.

I now use the NOS MiniGrands as my front-fill loudspeakers:

I also reinforced all 4 frames with "L" brackets inside each corner.

I now use my original pair with the older Graz ribbon as rear ambience:

I'm really happy with the results.
Mike

Nice work, and thanks for the posts! Ribbon speaker work is, as you found, kinda hairy given how easy it is to damage them. I knew a guy who's cat cut through some of the ribbon with it's claws. The cat lived, but was banned from that part of the house forever...

The material in the ribbon tweeter is incredibly delicate. When taking a tour of the Magnepan facility I got a chance to "play" with the thin, aluminum ribbon material. The people that work there are artisans.

Congrats on the rebuild
They can be very frustrating as you experienced
I was replacing the speaker protection in my Meridian DSP 6000(thermistor). Restoring the boards after delicate soldering a screwdriver fell across the v large power supply caps.
Big splash, expletives and back to the factory for a new board.....

PS what amps for the Apogees
I needed Krell 250 for my Scintillas
They had enough energy to boil a bucket of water with bare ends from the amp!
