Ah right. In terms of frequency; anything much over 120Hz will allow the sub location to be identified, so unless you can position it in the middle of the loudspeakers then a crossover of 100Hz or lower is probably best.Thanks for quick response ------ About 8ins - I have some poss longish throw drivers already, my Q was rather about the frequency splitting options given a standard 2 channel stereo output.
You definitely want a lowpass for the sub; don't try to send a full range signal to it as it'll just cause distortion.
Ideally there would be a highpass filter for the loudspeakers (so the low frequencies only go to the sub); though it can work without.
If you have two subs then you can have the left and right signals go into each separately; though generally you don't get much benefit with a low frequency crossover (as the sub location can't be identified by your ears anyway). With a single sub you can use an adapter to combine both channels to a single mono input for the lowpass filter + sub amp.
