I've seen those too and they are essentially the typical foam surrounds for this application only made in white foam. Lansaloy was white originally, but quickly yellows with time.
Its your backup plan if you want it.

I saw those on that auction site. I don't know if the price increase is worth it for white foam surrounds. The driver surrounds would still be "non-original" and as such I'd think that any premium on the resale would be lost despite looking more original. If the standard black/grey foams are functionally the same, then that's good enough for me.
As for my drivers, I've applied more DOT3 over the past couple of days. I've applied it to both the top and underside, the Lansaloy is now very soft. I'm going to let it set just a little bit longer to and then reinstall them in the C53 cabinets again. This afternoon or evening I'll fire them up again and note any changes.

I applied DOT4 (had some spare ATE Super Blue in the garage) to mine and it worked wonderfully.

Well, this is a bummer...
After applying a couple more coats of DOT3 to the surrounds, the Lansaloy was very soft and flexible, and had taken on all the qualities one would expect of foam. I figured that applying any more DOT3 would only lead to diminishing returns and reinstalled the drivers in their cabinets.
For amplification, I decided to use my (previously) reliable Sansui AU-517, with my matching TU-517 tuner as a source. Listening to the radio at moderate volume, I was quite pleased with the results of the DOT3 treatment; bass was significantly deeper while still remaining well-controlled. Really, I was quite surprised how good everything sounded.
And then out of nowhere the AU-517 decides to make a loud pop and release a torrent of white noise into the right channel! The speaker cone was traveling in and out wildly. I leapt to my feet and turned off the amp. After a few minutes of colorful language, I surveyed the drivers for damage. In total, the speaker saw about 2 seconds of full-volume noise, but that was enough to tear the Lansaloy surround a few places. Luckily, both drivers still work and I'm getting good continuity readings with my multimeter, and the woofer still travels in an out without the VC rubbing against the magnet. So the choice has now been made for me: I'm going to have to buy new surrounds. As for the Sansui, I'll have to wait until I get the time to open her up and see what wrong.

Sorry to hear about that incident. Did you refoam by now, and how did it come out?
This is my idea. Has these spares and worked up the crossover, put them on top, and BOOM! Sweet. Next up, another cabinet build for the 2344 and soon-to-arrive LE14H1s. The LE14 family is a GREAT driver. With the 2344s on top, these might as well be 4430s when I A/B them.
