Crossove Advice

[Gaz]

Hi All

I'm setting up a rumpus room with a basic surround sound system and need
some some advice. I have a surround amp with fronts, centre, rears, but no
subwoofer output, and I have a set of surround speakers with a powered
subwoofer. Any ideas how I can connect the subwoofer in?

I was wondering about connecting it in parallel with the centre speaker and
putting a suitable inductor in the line to only let the low frequencies
through, I gather a 6db/octave setup would be ok.

I've also heard about going across the front speakers, pos to left and neg
to right.

Thanks in advance.

**I can't recall seeing a surround sound amp which does not have a sub
out. Even the cheapest, crappiest ones have them. I suggest you have a
real CLOSE look at the back panel. If you still can't find the subwoofer
output connection, then you can probably find a surround sound amp at
your next council cleanup, that will have one.

And no, 6dB/oct is no where near enough. Nor would just connecting to
the centre channel. The only realistic way of connecting it, would be to
sum the outputs of the front channels, then running a filter.

Get another amp.
