these are HOG 30hz 24db LR / 65hz 48db but and ES18 80hz 48db but / 130hz 24db lr, and the sum after delay applied

got lots of other measurements. I didn't apply any eq in the last setting

This is kind of how I've played sINCE 2011 with FCS 960 & FDS360...maybe not with that combined gain structure...
all these measurements are of three hogs with 3 es18 above them, thats one of two stereo stacks Edited by king david - 14 January 2019 at 10:58pm |

I work on the basis of using the lowest order filters possible to protect drivers and put the different sections in phase across the crossover region. the other approach is to use the highest order filters possible so that even if the phase relationships aren't right the crossover region is so narrow you can't hear the problem. set your delays first. I think is simpler if you apply a 30Hz HPF to your whole system rather than just the hogs - it means if you change the 30Hz filter you don't screw up the 65Hz crossover relationships. having done this you can probably change the HPF and LPF on the ES18 to first or second order to get parallel phase traces. you won't necessarily get a flat response doing this but you will maximise the in-phase overlap between the subs and kicks which increases your max output. you can use eq to get a flat response if that's what you want.

[QUOTE=toastyghost]Can you post the traces? You need to be looking at phase as well as magnitude. I’m surprised your ES18 aren’t playing as low as they should, I’ve measured much better from a single box many times.

at some frequencies the Hog is going to be a reasonable absorber of sound and will affect the frequency response of the ES18 sitting above it.

It’s hard to tell what trace is what without the legend, but frankly I would say your BSS settings look better in terms of in phase summation.

I got some technicians I know to make it for me. their setting is phase and time aligned. the sub response isn't what I wanted as theres no low bass just a massive 60/90hz bass and while I can use that system for a party, in terms of 'dub sound system' sessions, I don't want any vocal out of the kick bins and I don't like hogs much at 90-100hz, when its just the bassline playing it needs to be just that, and I prefer have bit of headroom on mid tops, without any bass coming out of them. i have their preset on the dsp ;) I may still put butterworth 12db on the kicks if they would mix better with the hog that way
