Lots of bass at walls, lack of bass in center of room/listening position

The best success I have had is using the Vandersteen speaker placement calculations for the main speakers.  This is available on their website.  I have two subs.  I have 11 acoustic panels, diffusers and traps.  I can walk around my room and the music sounds good.  It was not that way at all previously.  Several peaks and nulls. Good luck.

...or as I suggested apply professional digital correction.

Thanks guys. Will look into treatment and DSP.
I do plan to move to a bigger space in 2-3 years so thats why I have the NS5000. But I agree totally a smaller speaker might be better. Although not sure it would be better for bass impact?

AHA !!!

If these are the original NS 5000 I strongly suggest you get Troel's crossover upgrades:

Everything I was complaining about in your measurements (except for the choppy HF) is fixed here.

Otherwise, DSP is a necessary option.  If you don't want to do the EQ yourself, Anthem makes a pre and integrated that will do it for you and integrate your sub.

If you're thinking about Acoustic Panels, you should consider making them yourself. The Rockwool Comfortboard 80 from Home Depot is as good as anything out there and it's only $58 for 6 pieces. It's very rigid, so you don't need to treat it at all. Check out the Acoustical Performance here -  https://www.rockwool.com/products/comfortboard-80/?selectedCat=comfortboard%E2%84%A2%2080%20downloads#Specifications&Sizes
For Bass Traps, just double up with 2 pieces for 3".
All you need to do is build a wooded frame, add the Comfortboard 80, and staple some Guildford of Maine FR701 cloth on it (about 5yds), which you can order from Duvaltex in Quebec. I added Cambric dust collection fabric to keep any loose particles intact, which is very cheap to buy (use 3M 77 spray adhesive to glue it on over the Comfortboard 80). Anything you buy won't be better than making your own.
