Default Mix and match speaker impedance

You could put on each of the 3 ohm channels 2x 6 ohm LSes, plus one of
the tweetered 6 ohms via a capacitor. Put all 3 in parallel. It gives
you 3 ohms at lf, 2-6ohms at hf, which is all good. Any modern IC
output amp will protect itself if you max out the volume, and speaker
impedances are only nominal, they vary quite a long way out in
reality.


Hi NT, thanks for that, but could I trouble you for an ASCII
schematic? Or a pic of a sketch. I am not as smart as you think I am.
What kind of cap, what value and voltage? If polarized, which way
around?

Thanks

Dave

Cap value, if we wanted 2ohms at 1kHz so it doesnt affect the existing
cap noticeably, that's 80uF. 47-100uF would be fine. Less might or
might not be ok.
