I've done extensive listening and confirmed that this connection sounds best.
Is this assumption correct?? I thought if you added a cap and extra speaker to the 2nd order xover circuit that this would change the circuit on a whole e.g the impedence would have to be calculated for 2 drivers instead of one. If not there would be a hole in the xover e,g the bass would be rolling off at 500hz but the treble wouldn't start to around 1000hz or so. Can someone please enlighten me!!!!
