2 - 16 ohms Bookshelf speakers?

Rmihai,

It's not which speakers are flexible - but which amp.

The speakers are loads. The question is whether the amp
can carry the load or not.

A speaker with a 2 ohm impedance requires more current than
a 16 ohm impedance speaker. Therefore, a 2 ohm speaker
presents a more difficult load to the amplifier.

Hence, if you have an amp that can handle a 2 ohm speaker,
that is - it has enough current capability to drive the
2 ohm speaker - then it will easily handle a 16 ohm
speaker, as the latter will require much less current and
presents an easier load. An amp rated at 2 ohms is the
more flexible amp.

Now if you have an amp that is only rated for 16 ohm
speakers, then it is not very powerful. It will require
a speaker that is very easy to drive - a 16 ohm speaker.

The amp that is rated at 2 ohms - can easily handle such
an easy load as a 16 ohm speaker.

Since the amp that is rated at 16 ohms is the weaker amp -
if you get a 16 ohm speaker - then the 16 ohm amp will be
able to drive it. So will the more powerful amp which is
rated at 2 ohms.
