I have not used or heard any drivers from Lambda, but they sound interesting. JBL began using Faraday rings in their woofers when they shifted from alnico to ferrite structures. Alnico resists flux modulation much better than traditional ferrite magnets with steel pole pieces. So JBL puts a conductive ring in the motor to counter flux modulation. In my opinion, this is the difference that makes JBL drivers of the last 20 years or so sound so good.
