Vandersteen 2Wq crossover

just go one or two down from what the lable dip settings says for 2wq and your amps input imp
for example for 100 hz its as on the lable says for five as
for 2wq go one dip setting down say 75 k and listen then try 2 down and listen dont foget to experiment with sub volume , contour to your preference get the spikes installed ,use a bubble leveled and snugged up let us know how you made out. johnnyr

OK, I'm not totally clear on this. So the dip switches, as they adjust for amp input impedance they also move the crossover point up and down? Sounds like you are saying I should just keep trying lower and lower impedance settings, which will effectively lower the crossover point? Is there any particular setting that will create an 80hz cross point, to match the sub?

First find out what your amps input imp is
With the 5s high pass dip settings are for 100 hz for 80 hz start going one setting down at a time untill you get it right if you dont know your amps input imp read the manual and start there. what kind of amp do you have?
are you running xlr or RCA?

I should have said before this is single ended (RCA). My amp is CJ MV-50 with 100k input impedance. Also, I favor a rich lower mid so prefer slightly lower cross where possible, such as 60 hz. My speakers are Snell Type A so flat to 35 or so.
The part that still confuses me is the difference between the input impedance setting and the crossover point setting. Maybe as you decrease input impedance below what your amp would call for, the crossover point starts to drop? Sorry for my ignorance here and thanks for your ongoing help.

One correction: typo... my amp is MV-60, not MV-50
