Servo controlled speakers and subwoofers

What does a servo control do for a speaker and subwoofer?

Given the same sized woofer, is a servo controlled subwoofer inherently better than one that's not servo controlled?

The Genesis 4 chassis speaker systems uses a servo control. Why a servo instead of letting the woofer columns be powered by a regular power amp?

Nsgarch, what are those colums with 5 woofers per side in your system? Do you use a servo to drive those giants?

Mitch, actually, I don't use those SW-800s (Kinergetics) anymore. I use a single Martin Logan Depth and it's great (it does use a servo, BTW) Sorry about the outdated pic. That's one of my spring projects.

Most on-board sub amps are I believe Class D "switching" amps. They're designed to only drive the lowest couple of octaves. I'm not clear on why, but they don't require big power supply transformers or storage capacitors.

You still need a "regular" Class A or A-B amp for the mid/highs, although there are now some alternates to those as well.
