How to wire a powerful amp with two speakers to avoid damage


I have read that it is possible to use a pair of speakers as a "resistance" to prevent damage from overdriving speakers that are to be low powered. How can this be done?
I have a pair of BC2 Class A hybrid mono amps at 75 watts per channel and would like to experiment connecting them to very efficient speakers such as the Soliloquy 2A3s, but I am afraid that it might be an overkill....2A3s rated at 25 watts max.

Paul (& Angela) the amp would barely be working hard at all & probably wouldn't get much warmer than it runs at idle dissipation. You can in fact operate very high powered amps into low-wattage speakers without doing any harm at all, provided that you exercise reasonable restraint. We once drove some 100-watt-rated B&W speakers with a Mac2500 amp (500 w/ch. conservative) with no problems. In fact since the Mac never went into clipping, we were able to drive the B&W's at about 300 watts before they were audibly straining to handle that amount of power. At any higher power level we would have gotten in trouble burning up a voice coil, but as long as you're even reasonably careful then there is no problem in doing this.
