Little project I've been working on for a while... first prototype rolled out yesterday. It about 4 1/8" deep -- power handling and other specs will be announced once we finalize the coil (several variations will be tested).
Every part was custom tooled; frame, diaphragm, dust cap, spider, surround, etc, etc. It also features an aluminum pole cap to lower distortion even further.
Stay tuned for more information as it becomes available =)
