In regards to a post I made in another thread, my beloved Audax Aerogels haven’t weathered the times. The surrounds have stiffened up. While screwing around with a set by adding weight to the cone to see how much was needed to alter Fs in an appealing way, I inadvertently found out how fragile the cones are.
I always assumed the cones were a paper blended with aerogel and a coating of some sort. Well I found out the cone is some sort of blend not unlike styrofoam with a coating. When I removed a wheel weight I had stuck to the cone a whole piece of the cone came off with it. Shit.
So after perusing AliExpress, I found some cone/surround parts. I ordered some neato orangish fiberglass cones with rubber surround. I then proceeded to try to remove the aerogel cone/surround from the VC/frame. Separating the cone from the VC at the neck joint was actually quite easy. A scalpel and some patience was all it took.
The fiberglass cones had to small of a VC opening, so I had to cut that. I used a pair of curved fingernail scissors. I carefully opened it up for a nice snug fit. No dust cap made it easy to shim the VC in place. I made sure the VC height was approximately centered/spider was flat.
I used black cyanoacrylate glue and activator to attach the two. Then I used some wire to hold the surround up out of the way while I ran a bead of glue around the frame, same glue.
Then just layed the surround down and the super glue did it’s thing.
Done…
Ran some measurements and overall they work again. How well…
I’ll figure that out when the time comes. They definitely have a cone breakup indicative of a FG cone and looks like a surround resonance, but at least a possibility of some useable drivers..

I still have an old Zalytron catalog somewhere. That was my first real introduction to Focal that I remember.
Cool stuff!
I still have my old 1985 McGee Radio & Electronics catalog. Bought alot of drivers from them back in the day.

I knew a couple of guys that worked at MTX in Monroe WI back in the late 80’s mid 90’s. My crew and I were heavy into car audio back then. None of us competed with any MTX gear even though it was somewhat local. Rockford Fosgate, Soundstream, JLAudio , Orion, AudioControl, and Precision Power were the kings back then.

I still have that one too.
I ripped a no longer functional aftermarket remote start/door lock kit out of our spare car. Hoping that fixes some wierd electrical issues my wife said it has had ever since it was installed over 10yr ago. They did the 'ol part the strands and shove the new wire through then wrap around. Kind of grateful for that actually, as the wires were otherwise intact to wrap with tape+a wire tie to lock the tape down. Only one wire was cut for putting the unit in-line. They soldered those connections so I just soldered the wire back together. Biggest PITA was they used a ton of tiny pieces of electrical tape. Most of my time spent was peeling off a tiny piece, then trying to find the end of the new piece, repeat, repeat, repeat… 
I think the piggy back immobilizer bypass unit lost its programing or otherwise went south. Tried to reset it to factory defaults but no change, the LED still did the slow red flash.. doors would no longer lock/unlock (though it would give the key-in-ignition door open ding). remote start function would start the car but immobilizer would shut it back off immediately.
I think this may apply to many new cars with smart proximity keys, but if we have our mobile phones too close to the Mazda ‘key’ (more of a matchbox these days), the car won’t unlock, or won’t lock when you walk away after closing the doors.
Very strange, but it seems to be a known issue with some modern Mazdas.

Interesting, I wonder if those proximity keys listen for the car’s signal to respond to it. The receiver probably gets overwhelmed/jammed by the phone signal.
Probably; another related thing with those ‘keys’ is that you should not keep them too close to the car when you’re not driving it. The key keeps ‘talking’ to the car and telling it that you’re about to drive it, so the car’s systems are activated, which can drain the battery. We discovered that in the first month of ownership.

Highlights from Australia’s Bathurst 1000 “V8 Supercars” race, always interesting when it rains:
The race, held at Bathurst since the mid 60s, was originally for standard production cars, then morphed into ‘series production cars’, then on from there to the current rules. It’s a dangerous, demanding track which has claimed many lives over the years. It’s too dangerous for Formula One now, but motorcycle, open wheel Formula and sports cars have raced there.

Lyrics from 1:50 to 2:02 mm:ss are spot-on. (DAMHIK).
Facial expressions resemble eargasm ensued in numerous places. - good guitar work.
I can’t dance to it though, so this is mental music, IMO.
Tool is cool but . . . Beat of a different drummer for sure.
