What are your mains? Have you tried measuring away from the MLP (Main Listening Position), and if so, do you get a significantly different response?
Also, the punch-in-the-chest mid-bass you're looking for doesn't really become noticeable until pretty high SPL levels. What MV (Master Volume) level are you listening at? I only ask because your graph was taken at a very low SPL.
My system is 5.2.2 front heights. All HSU bookshelves and center, HSU VTF3 MK5's for the subs.
The 'suckout' seems to be everywhere. I've made radical changes to the subplacement and measured in other places.
Can someone with minidsp confirms this works:
1. Your minidsp is NOT hooked up to your computer
2. You make some changes on plugin application on your computer
3. You THEN unplug minidsp from your system and plug it into computer
4. You hit 'sync' button - and voila all changes are on there.
Is that how it works? Because that's what I'm doing. And no changes are apparently being stored, because before and after graphs are identical.
I'm starting to wonder if you have to hook up minidsp to computer and hit sync - and then and only then make changes - then go hook it up to system. I.e. you have to make changes while it's hooked up and synced or they don't stick?
If anyone has done it the numbered way above, let me know. Then I will know I just have faulty minidsp.
