I'm running as most know the TourX 2x15's and 2x18's and plan on hooking up a second amp to power the subs separately. With an electronic crossover where is the best place to set the crossover point?
EV TourX Crossover Question

You might want to check your spec sheets from EV, because the information might be there.
Let's see accourding to the manual the range is 50-160hz
The tops have a recomended High Pass filter setting of 40hz, but that seems a tad low....
When I ran one sub with my ZXA1's I had the crossover point somewhere around 85hz and it sounded fine.
Really i just need a good starting point....

My CV's get fed 100 Hz and lower and my custom loaded dually 15" subs get 120 Hz and lower. I use a filter to cut off anything below 30 Hz with the CV's and 35 Hz with the 15's.
Start at the 85Hz and work from there to optimize the sound. That might work for you.
More than likely that's what I'll do once I have a setup that I can do that with... I have everything but the amp yet.
The high pass filter is for the subwoofer not the tops. It stops frequencies below 40hz so your sub doesn't have to reproduce them.
85hz is a good starting point. You'll probably use a xover point somewhere between 80hz and 120hz.
Once you have the crossover connected turn down the gain on your top amp, set the crossover to 80hz and listen to just your subs with some music with strong bass that you know very well. Now slowly adjust the crossover point higher. You will probably find a point where the subs stop sounding musical or start making odd noises. 18's probably won't go much higher than 120hz but with your 15" mains that's plenty. Some 18's start sounding odd as soon as 90hz, don't assume that you can go to 120hz or higher until you have tested it.
Now turn down the gain on the sub amp and turn the gain back up on the main amp and listen to the same song and start with the crossover at the highest point that your sub sounded musical. Now slowly adjust the crossover point lower until you stop noticing it adding more bass. That's the lowest you ever want to set the crossover. This requires much more critical listening than checking the sub!
You can do this at home as an initial pass and to get familiar with the process, but you really need to do this in a large hall where the bass waves can fully propagate. You want the subs and tops setup where you plan to use them. Tops will have much less bass capability mounted on poles and this is where you need to check them.
You will then know what you have for range to test the full system. If you don't have time to test this before your first gig, you should be safe setting the crossover somewhere between 80 to 100hz with your setup.
Even if a sub sounds OK as high as 150hz or higher (a 15" front loaded sub?) you typically don't want to go much higher than 120hz or you may get some (electronically enhanced) deep male voices steering between the mains and subs which sounds really freaky.

Thanks that answers that question....
Next one....
When running the subs off of a Q99 amp would you:
A. Run the amp in bridged mono and connect the subs in parallel
B. Run the amp in parallel and connect both subs to an output
Hey Rob when you get that second amp you should really consider getting a DC One next , you won't regret it. I know it adds up but maybe add that to your list as your next purchase, it really is the heart of my system
