The SuperZero while a nice sounding satellite speaker has little to no real bass.
It only has a little [small] bass, below 100 hz
The SuperOne 2.1 has a bigger woofer and bigger box - and will have some bass
and punch.
I owned the SuperZero speakers in the pass and the Classic Two speakers [which.....
also has a 6 inch woofer] - and there is a big difference. NHT rates the bass specs
in the SuperOne 2.1 about the same. So, I am confident that it will have bass.
If your expectations are not real high - then the SuperOne 2.1 can hold you for awhile
bass wise. Some people are happy with the results - however a sub will be beneficial
in the future, to pick up that deeper bass response for Home Theater and deeper bass
music listening.
The best way to place any sub, is to do the subwoofer crawl
