Default What speakers can I use with my 4 ohm amp?

I have a Cambridge Soundworks FPS2000 as the output for my computer's
audio. If I can,
I would like to replace those 4 satalite speakers with
the ones that I have left over from an RCA RV-9967 receiver, but I'm not
sure if that would be okay.

The 4 satalite speakers that came with the FPS2000 have 10watt @ 4ohm
stamped on the magnet. There is no detailed documentation for the amp
that comes with it, so I can only guess at the amp's rating based on the
speakers that came with it.

The 4 speakers from the RCA receiver that I would like to replace
them with are its two fronts (50 watts @ 8 ohm) and its two rears (25
watts @ 16 ohm).

Considering that the FPS2000's amp appears to have been designed for 4
ohm speakers, could I still use the 8 and 16 ohm speakers with it?

Would that harm the speakers or the amp to do that?

Won't harm the amp, as it will basically be underloaded. You might
notice lower volume with the higher-impedance speakers.

You were wrong, and I'm man enough to admit it.

No, the only potential harm would be if using speakers of *lower*
impedence.

No harm, but keep in mind that the power rating of the amp will be
halved.

*Less*, but not necessarily half for an amp with the usual unregulated power
supply, and usually more than half on a continuous basis in any case.

The amp's power 'rating' won't be changed at all. The maxiumum power output
will be somewhat lower than that with the impedence speakers it was specced
at, probably around half.
