is this one function of the magnet? I assume better control of cones etc?

Damping of a speaker is a combination of its physical characteristics, its electrical characteristics and the size and tuning of the box it's in. But basically it's the shape of the bass roll off. But still even if a speaker is well damped(most really aren't so they sound bassy to help sell them) at the impedance rise(closed box) or rises(ported box) the bass will be fuller than for a high damping factor amp(usually a solid state amp). A damping factor of about 20 will have a measureable but trivial affect. Unfortunately most tube amps have a damping factor below 10.
Still before solid state amps everyone used tube amps and they weren't that bad. And current tube amps aren't that bad. They just don't control the bass as well.
If you're using a monitor subwoofer setup I don't see that as much, if any problem. My SR71's roll off wonderfully at around 45-ish hz. Then the sub picks up the rest coming off the preamp or source. Either way the bass sounds just fine and articulate.
I agree if you are using a traditional (vintage style) full range or multi driver speaker. Then the bass can get tricky!!!
But the initial question didn't mention subs. So that's how I replied. And while tube amps react differently than solid state amps over the whole band width, it's the bass where the differences are most evident.
tubes have such a nice midrange too.

everything has colorations. you pick the compromises you prefer. as my friend Murray liked to say, 'color me perfect'
