Subwoofers Does Size Matter & More?

Not to mention that driver excursion causes bending of woofer, distortion and less controll.
This is why most good manufactures add servo controls, but this is still a help after its too late.

Good points. I always bring this up, but excursion is one of those things that people today seem to be trying to get more and more of. Not me. Too much excursion ruins sound quality. Go look at car audio.

To be fair, excursion relative to the woofers motor has to be quite high before any control (or even transient response) is lost, and most woofers won't bend unless driven too hard - the surround bears the brunt of the force, and even most cheap woofer materials are strong enough to not worry about woofer bending until driven too hard. If you buy the right sub for your purposes, you won't over work it and have to worry.

Servo's are definitely necessary though when you cross the line and want super loud SPL's with great sound quality. Though the best subs I've heard have not been servo. I think in most homes it's overkill. Get a good woofer of good sensitivity instead.
