The installation process for the SP2500 did not present any issues once everything was out of the super big box laid on the floor. Because this is a 2.1 system, there really is not too much equipment to deal with.
The system does not require anything but a stereo signal and power to work. However, the small control unit does feature firmware which presumably can be upgraded for whatever reason - perhaps new EQ curves.
Placing the speakers themselves is fine as long as there is not a need to have them far from the subwoofer (amp) unit, because while the provided speaker cables are nothing short of excellent, they are in fact quite short of being what you would call lengthy.
It's also important to remember that the SP2500's have been designed with a centre 'sweet spot' in mind - That being that the users head forms the topmost tip of an equal-lateral triangle with the height plane also being equal from the speakers.
