Sounds very confusing to me...I have never seen a speaker with a switch for "fullrange" those are on speakers and they are for bi-amping... however those speakers are not bi-ampable..anyway...
So second problem is,... those speakers have 90 degree horizontal pattern in the HF range and overlapping the coverage of the speakers is going to cause sonic chaos..(phasing, cancellation, modes).
My plan was from DBX DriveRack PA + as a 3 way sound.
FROM: Main (1) output from mixer
Low = (Gemini GVX series powered subs)
MID = (Behringer EPX3000 amp) with (Gemni GSM 3250 speakers)
HIGH = (QSC GX5 amp) with (Gemini GSM 3250 speakers)
Well I think you mean a dual stereo top with subs??? and I told you above why thats a bad idea...but in the spirit of disclosure... you select a bi-amp tops and subs config and lower the HPF of the hi outs so that the frequency range is 100 hz LR24 to out- Set the mids LPF to out and the HPF to again 100hz LR 24.
The subs then would be 20 hz LR6 (letting the powered sub do it's own HPF) to 100 hz LR24.
