Regarding the miniDSP i ordered both 88A without the BM plugin and external 2x4 balanced and one more UMIK 1, will let you know once its been delivered.
Thank you for your help
Yariv, I successfully downloaded your measurement file and took a quick look. The first thing I notice is a very significant 16dB dip from 40Hz to 70Hz in the front channel. I suspect the cause of the dip is how you have the center speaker mounted. Before doing much else, we need to understand the cause of this dip, and then fix it. This is priority no 1.
What flexibility do you have with respect to equipment placement? And can you put treatments on the walls? Is that a dedicated listening room, or your living room? Do you have an open-minded wife, or will there be severe limitations to what you can do?
Here is a frame-breaking idea for you to consider:
- Move the equipment rack off to one side of the room out from under the TV (equipment racks in the center are a bad idea from an audio perspective)
- Remove the center speaker from its wall mount and place it on a dedicated center speaker stand away from the front wall (see the "My Setup" link in my sig for an example).
- Arrange the Left, right and center speakers so that each is exactly the same distance from the MLP
- Make sure the left, right and MLP form a triangle (ideally equilateral)
At the very least, we need to conduct some temporary
, alternate locations for the center channel to see if we can eliminate the dip.
- Remove it from the wall mount and place it on top of the cabinet in between the Marantz and the Emotiva, with the front of the speaker all the way to the front edge of the cabinet.
- Place the center speaker on a box in front of the cabinet (temporarily)
- Measure each of these locations to see if the dip is improved/gone.
Later we can discuss bass resonance and room reflections, but we need to fix the center channel first. We can talk more tomorrow.
