Room correction with D400 and B&W 800D

[dbilling64]

That's the 'flattest' in room response I've ever seen without applying serious DSP for room correction. I'd say it's almost impossible unless your system is outside, in an anechoic room or a VERY well treated room. I doubt the measurement is correct unless you've put some serious effort into treating the room. If all checks out right, hats off!

The screen shot I posted is with smoothing applied to the data to highlight the effect of SAM on the bottom end. The raw data does look less flat particularly higher up the spectrum.

The work is being done by a specialist company that does recording studio preparation work. It is a dedicated listening room so I don't have any constraints on aesthetics or have to compromise for other uses of the room. The net effect is that it does look a bit like a recording studio now - which I don't necessarily like - there are cloud panels hanging from the ceiling and absorption/diffusion treatments to all 4 walls. The audio improvement is significant though - albeit at medium to high volumes. Low volume listening can sound 'flat' and I may need to remove some of the absorption to get a better all round compromise.
