Cross-Over Confusion

[Gary Hubbard]

I am wiring up the crossover for a Dynaudio W75/ Fountek Ribbon 2-way with an out board crossover. It is getting really complicated to bi-wire from the amp to the cross-over and from the cross to the speakers. Which side is more important to bi-wire and am I really as crazy as I think for doing this?

If I have interpreted what you have said correctly, then you must "Biwire" to the speaker drive units. This is because if the Xover is external then the speakers are running full range. In this case its not really Biwiring its just wiring as the speaker won't work correctly without it.

If you connect the Xover outputs together you have effectively taken the signal from the amplifer split it into low frequency and high frequency and then joined them back together. Both the drive units will recieve low frequency and high frequency. This will sound rotten and probably destroy your tweeter if you play it loud.

Sorry if I have miss interpreted your description.

Hey Gary.

Is it an Active or Passive external crossover?

[Gary Hubbard]

The out-board cross is divided into high frequency and low frequency sections. The crossover is now finished, bi-wired from the common amp outs to each section of the crossover and thence to the mid-woof and tweeter terminals on the speakers. I'l report how it sounds when fully set up. Mother H.
