I tried a few calculators and ended up more confused!

The goal:
Block below 160 and above 6000 from some tiny speakers, on their own leg of an amp, no other speakers on this leg.
They are '4' ohm, in parallel, read 2.5 this way.
The work fine, but I want to protect them from lows and my ears from highs!
I also want the most efficient filter arrangement.

Most sites seem to show a capacitor for the lows, in series with an inductor for the highs, in series with the speaker.

Should any or either component go across the speaker?
