Vandersteen 2Wq crossover

you wont know what u
r 2 prefer untill get the assessement box and do the assesment
best johnnyr

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

((((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?
