You wont be able to hear anything lower than 20Hz. Even if your sub/sub box can play it.

So look at the higher frequency, The highest frequency a sub should play is around 80Hz.
Some headroom is okay, but 350Hz is overkill. That's midbass territory.

All three sound like good candidates doh. Maybe we need to judge their other parameters

What are the three amps in question?

Manufacturers throw in their bandwidth on the specifications sheets very loosely and expect us to take it. How is it measured? -1dB?-3dB? -10dB?

Sub duty is usually around 20hz-80hz

As said before, sub duty is about 20hz to about 80hz.

I'd be more concerned about the filters / slopes.

Depends on your enclosure, fs, cone area, driver displacement etc etc.. some subs have fs around 12-16.. depends on how you like your bass too.. if you like that subsonic bass then go for 8-180 also you can also function within 20-80 hz so you have more options with the 8-180.

Hadda be a really big sub with a heavy cone
You got me thinking there , remembered the rediculous MTX jackhammer.

It had an Fs of 20Hz with 1.6kg of moving mass and a 24 inch cone

when u ask about "a better control of subs" , technically u shud be looking at d dampening factor of an amp - google it

also alot of sub amps companies will rate their stuff as "20-300hz" etc but does that really tell how it sounds in real life ... will a boss\power acoustik against a good ole skool rockford or jl amp sound similar even though its bandwidth might be similar ? - hell no

some amps do not sound as equal across their rated bandwidth , some do poorly under 50hz , some can actually make d roll off appear to sound 5-10hz lower than what d enclosure is actually tuned to

choose reputable brands ...
