Replacement speaker?

Hey gang.

Just wondering, is the internal speaker in the Falcon the same as what's in the
STacy?

If it is, is it exactly the same or being newer, is it of better quality, reproducing
better sound?

Or is it possible to find a drop-in replacement speaker today that will improve
the quality of sound? The factory/stock model looks like a fairly cheap one.

Has anyone already tried this?

Thanks!
