Just a quick bit of info until I get time to put it up in my section. The driver uses MMAG technology (think older striker pro with clear cap). It uses 25mm thick plates the main magnets are 270mm OD and the Diode magnet is 220mm. The current coil in it is an "SPL" coil to give it massive amounts of motor force. In this configuration it is around 2,800. However with this big 8 layer 95mm long coil there is a down side, inductance. Which we all know kills top end bass. Plus it just has too much force for its own good. The spider pack is twice as hard as an IA Warden and still moves ~15mm one way free air on 500watts. Efficiency rating on this set up is ~92 1w/1m and ~99 at 2.83 volts/m
I will be tearing it down soon and putting in the "normal" MMAG coil which will give it a motor force factor around 400 and offer 42.5mm of one way linear Xmax. By June I will have engineering complete and tooling made for soft parts that will offer upwards of 60mm one way linear Xmax which will be needed to support the motor offerings that will be avaliable this fall. In the mean time this motor, if Klippel testing goes good, will be offered in beta form with 12 spoked baskets which offer ~32.5mm throw one way which i have Klippel graphs on and will be posting soon.
