Speaker impedance is not a fixed value.
Speaker "resistance" is a fixed value of usually about 4 - 8 Ohm.
Speaker impedance varies according to the frequency of the signal going through it and is usually expressed as the average or norm value (around 8 Ohms).
A speaker impedance of 1 Ohm might blow up some amplifiers.

Loading an amplifier at 1 ohm, even if 1 ohm stable, doesn't mean it's best to do so. You actually increase THD (total harmonic distortion), run the amp hotter and shorten the life of the amp as a result.
It's best to find an amp that pushes the watts RMS desired at a higher impedence for better quality, longer life of the amp and cooler running of the amp.
An example, if you want 300 watts RMS to hit your subs and your subs are 150 watts RMS @ 2 ohm each, wire the subs in series (4 ohms) and get an amp thats 300 watts RMS @ 4ohms.
There is one person out there that swears running in series sends an unbalanced signal to the subs and this couldn't be further from the truth.

never heard of a 1 ohm speaker, but I suppose there could be one. The usual ones are 4 or 8 ohms.

Are you sure? I dunno about that...
