"I would think regular speakers would work."
Speakers require a fair amount of power to make sound - so you need an amplifier to drive them. You can't simply connect a signal source, like a tuner or the Dot.
The description of the "speaker" connection is rather vague, but from what I can see the output of the Dot is a low level audio connection, I think the supplied audio cable terminates in RCA connectors, which would be plugged into the input of an amplifier.
If you have speakers with internal amplifiers, then a direct connection would be fine. Otherwise, an amplifier of some sort is needed in between.
Most non-powered speakers will have either screw terminals or binding posts for input (although some do have RCA jacks, which really confuses things).
