Axiom Home Page Forums General Discussion Technical Questions Crossover slope EP600

I was wondering if anyone knows what the crossover slope is on the EP600. I have recently purchased a Hsu MBM-12 and I am trying to figure out if it would be better to crossover the 600 at 40hz or 60z (currently at 60) The MBM has a high pass of 50hz and since that is not an option I am trying to figure out eh best way to blend these two.

If you are using the crossover in a receiver what would that matter? The crossover in the 600 would be bypassed.

exactly Rick, the receiver handles the bass management and the 600 should be bypassed.

Well that's the thing with integrating an MBM, it is designed for 50-150hz I set the controller's crossover to whatever I wnat the maximum frquency of the MBM to be and then adjust the 600 crossover to cover the 50hz and below. Knowing the slope would help, but I can use an SPL mic and REW to play with it and adjust as needed.

you would be better allowing the 600 to handle the full range set by bass management, which would give you a flatter frequency response within the room using multiple subs.

I guess you could call Axiom to get your answer, but I would want to use the full capability of the 600 WITH the MBM.

What mains are you using?

Monitor Audio RS8

Those are some fine speakers there. I'm sure they handle anything below 80hz just fine. I would set the crossover at the appropriate setting (whatever you find best) and just over lap the mbm and 600 by 10 to 20 hz.

I believe a year or two ago, a brick-wall filter was implemented for EP500 at 150Hz (and any of its other settings?). If the 600 has the same brick-wall filter, you will not get a slope (i.e. a smooth transition on the 600 side) at the set frequency on the 600, so as Wid and Sirquack have suggested, it is probably best to keep the 600 at 150/bypass and let your processor/receiver apply the bass management and slope on its side. Doing this would allow you to slope into MBM and 600.

John, I think your right, sometime mid year 2008 I believe new 500's and 600's hitting the market eliminated the brick wall filter...
