Have another question here......

I found an somewhat old 3-way speaker downstairs which hadnt been used
for a while. Anyway, I opened it up, to find the following:

The audio signal (+ and - ) connects to both terminals of the woofer.
Then from the +ve (of the woofer), there is an 1uF electrolytic cap
connected to the +ve of the mid range. There is also two 4uF caps in
series connecting to the tweeter +ve (from the woofer this is). All the
negatives connect back to the negative woofer.

Is this normal for the crossover ???? Or very very basic?

I am new to audio, but am learning alot .... have not looked in too
many speakers yet and so just wondered. I would have expected there to
be an inductor - but is this not needed as the main audio signal feeds
into the woofer, and so instead the mids and high frequency is
'removed' and sent to the mid-driver and tweeter???
