I am running the VRX 932 cabs set to passive. And the amps is running in dual mode (Left and Right). so to sum it up i am running 1 Vrx cab on each channel.
The SRX user guide gives recommended crossover frequencies (HPF: 80Hz, 24dB/Octave - LPF: 80Hz, 24dB/Octave) for my SRX 718S Subs. this is great as i can make a preset that follows these setting. But in the VRX user guide the only information they give you is what i wrote in my first post, no HPF or LPF setting are given, nothing as easy and detailed as in the SRX guide.
You are underpowering the VRX's running each cab off each side of the XTI. If your running dual mode 1 VRX cab on each channel, they are only getting 650W at 8 ohms. You want to bridge the XTI's and run 2 cabinents off of each amp. At 4 ohms bridge the cabinets will get 3200W combined at 4 ohms (each cabinet will get 1,600W). Dedicate 1 amp as a left and the other as a right to get stereo. See the system specs for the VRX 932's.
For the crossovers. since your running passive, hook up the amp to a PC using System Architect and manually input the crossover setting. The tunings on JBL's website has the highpass at 81.1Hz L-R filter 48db/Oct for the VRX 932's. The lowpass is run out. Hipass on the subs is 31.3Hz BW 18 db/Oct Low pass 81.1 db/Oct L-R 48 db/Oct.
Thanks for the help Shane.
Running in bridge mode am i not then over powering the VRX's?
Should i run the amps in bridge mode when driving the SRX 718 subs, giving them 1,600W each too and run one amp for left and one amp for right?
Oh also, the crossover frequencies you gave me, are they for the SRX 718S?
