As you know, I've been one of the biggest proponents of the Lambda lineup of drivers since back during the early days of Lambda Acoustics. Over the years, there has been a lot of interest in a group buy and with the econowave project from audiokarma.org still going strong, the interest seems to be getting stronger. I know I can probably get 2 dozen or so drivers of various sizes in the group buy just from people from Audiokarma.org, not to mention a lot of interest from AVS, Audiocircle, and DIYaudio.
If there is an appropriate venue (on this site?) to arrange it, let me know and I'll start gathering the details. If this is feasible and you could give some direction here, I'll start to get people to wherever you point us to.
