The original post was
Can I use the EQ (mix8) to get a sub driven Aux
There was never any mention of crossovers for mid way or for high end horns?
and my response was:

I do this all of the time into (powered 1200 watt B52’s) and non powered Subs using Lab Gruppen 4k amps
However I cross at about 100 hz
all faders (except 30hz left at 0db) 40 through to 100 I raise up. 125hz I leave at 0 (sometimes right off). the rest of the faders I bring down to off.

Not technically Ideal however it works fine.
Use your ears and be careful and actually go and look at your driver cones to make sure you are no pushing them too hard in those conditions.

Never any mention of crossovers for mids of highs.

When I use my powered B52 (and I have 12 of therm) I use the on board QU EQs from 100hz. The B52 already has a lousy crossover at 80hz and they have phase reverse etc and all the bells and limiters.
I bont do any crossing for my high mids… they have a built in passive crossovers and i’m able to virtually leave the desk EQ flat! Brilliant! Never sounded better.
However when I use my Lab 4ks to drive low subs (double 18’s 6 of them) I still use the EQ in the desk (Aux driven 7/8)
however I use LAB GRUPPEN 3 way very high tech spec crossovers. Anologe 3 way Bal crossovers.
Never would I cross over mid highs etc…
However thanks for all of the info.
Ive have built crossovers and know what’s involved.

Must not forget that original post… at grass roots level…
Some people just can not afford that wee extra peice of equipment.
And remember once you own a peice of apparatus you can do anything you want with it.
Even stand on ity like a tank commander.
