Hi Derek,

Not to sound ornery, but your friend was wrong. Specically, I said cone mass plays a factor in the time taken for the woofer to stop after the signal has been removed. I did not say larger diameter cones have worse transient response, as they dont. Also, I did not mean larger cones flex more, as smaller cones can flex just as much as Brian said. Essentially, the cones physical diameter has nothing to do with transient response, its a contributor of cone flex but thats not tied with larger diameters having worse negative effects. In terms of cone weight, comparing two drivers and making a decision based solely on this is completely wrong, as theres just too many other factors to consider.

As for what value of inductance is considered high - its hard to say really. I would view it as a way to compare drivers, but I would never make a decision based just on Inductance. The Peerless XLS drivers have voice coil inductance of about 4mH, and I consider this drivers very good, and they are better than Shiva and various other drivers for academic reasons (Shiva also has lower inductance, but the Peerless is still a better unit).

Adrian
