Anyone's tried repairing/upgrading original Vandersteen 1 speakers?

bdp24,

Nelson designed the "Ion Cloud" loudspeaker while at Threshold that put out a huge amount of ozone due to the ionized gas it used and took several kilowatts to get it to work. I've read it actually drove people from the room due to the ozone and caused power dips in the electrical grid due to the power draw but he said it was one of the best speakers he has heard! 

He also designed a device called "The Shadow" which was an active bass trap. It had a microphone built into it that sampled the acoustics of the room and put out an inverse signal to a woofer that cancelled/mitigated the high pressure acoustic bass waves. Brilliant design that for the life of me didn't catch on.

I real interesting article about his early days can be found here for those interested - https://www.stereophile.com/interviews/1191pass/index.html

@nmmusicman: Yeah, I remember that speaker. It and Nelson are pictured together on an old (digest sized, J. Gordon Holt era) Stereophile magazine cover. I need to dig out my copy and reread the report on the speaker.

@OP,
Either contact Vandersteen directly or John Rutan(audioconnection).
You can also post at the Vandersteen forum-on the Vandy website. We'd love to hear from you.
Vandersteen offers great customer service. You'll probably need to buy 2 drivers, as they are matched. There are videos on Youtube that show how to replace the drivers. Models 1-3 were designed to be easily repaired. Just peel back the fabric and do what is needed.
Crossovers usually aren't the problem, but, who knows?
Unless you are getting them for $100 bucks or less, I would look elsewhere. You can find plenty of working model 1's at reasonable prices.
PM me if you need additional info.

Millercarbon, may I ask what version of the 1's you owned. They changed a bit over the years.

I'm running Vandy 1ci's with Belles Aria monoblocks and preamp and they sound ridiculously good. The fact that I paid $400 for them makes them all the more sweet. The 1's when setup correctly will reward you when paired with good sources and upstream equipment.
