To EQ or not to EQ - That is the question!

[E-Stat]

Odd, Mr E-Stat. Very odd. I never liked the Tympani driven with ARC amps..... too agressive sounding to me in a very unnatural way.

Curious repponse. In over thirty years, I've never heard anyone before call the SP-3 and D-76 "aggressive" or "unnatural".

Cones stiff enough (and therefore heavy enough) to perform as rigid "pistons" driven by a voice coil at their apex simply have too sluggish a transient response to compete with an .0005 mylar diaphragm moved by a distributed force. The mylar is not intended to act as a "rigid structure" so all that "reinforcement weight" goes away.

You're forgetting something. Unlike electrostats where the diaphragm mass is the only moving component, you need to add the mass off all the magnets attached to the diaphragm in a Maggie (ribbon drivers not found on the Tympani series excluded).
