An amplifier is integrated into the device. An audio amplifier takes a small signal and makes it bigger without making any other changes in it which results in better sound, so any sound source can be connected to speakers.

Devices with a subwoofer have a higher quality, deeper bass.

A passive radiator looks like a normal driver (speaker) from the front, but on the backside all of its 'guts' are removed. Passive radiators allow woofers to produce deep tones that otherwise may not have been possible. They can have the same sonic output as larger speaker cabinets, but in a much smaller size.
