Finally my drivers and boxes are on their way to me and should be here in a few days,so I decided to start researching for the correct settings.

Other than the fact that I need a 50hZ low pass, I can't find much else.

Anybody with experience can chime in regarding this?

50hz high pass, not low pass. can run them up to about 150hz.. any other setting will be dependent on what speakers you have above and below.

Nothing below,and some generic reflex tops above.

Any other advice?

If you're using at least four HD's in a stack you may get away with high passing a little lower, say 45hz, also, if you have reflex tops above then they may need a delaying to the HD's to get everything coherent and 'punchy'.

Great!
Thanks to both of you for the solid advice.

It's been a few years but I recall the delay length from reflex to HD15 being about 70cm, you can set this on the tops in your DCX.
