RE: Electrostats are slow

Posted by hahax@verizon.net on November 24, 2020 at 20:34:46:
Acceleration, the ability to follow wave forms is a function of power to weight ratio. Electrostatics are very light per area but their motors are weak relative to dynamic drivers. This is inevitable because motor power diminishes rapidly over distance and the gap of an electrostatic is huge compared to a conventional driver. It has to be so the driver has room to move without hitting the motor. In contrast the coil of a regular driver fits in a very narrow gap.

In addition while a planar is light per area dynamic drivers while heavy are their moving parts are still quite light. Domes are a couple of grams. Even woofers weigh(off the top of my head) ounces. So their powerful motors with still light weight give a very good power to weight ratio. Sorry I wish I had numbers for comparisons. That would be interesting.
