When you say "null's" does this refer only to the negative dips on the graph or can these be the positive peaks which might cause problems also.
All I can make out from the graphs is that on the REW one there is an ideal flat frequency response line in blue and most of the graph from my measurement sits underneath this apart from 4 peaks.
My guess is that the lack of bass response here is due to the fact i've not treated the room yet and these frequencies are building up in the corners but I'm not entirely sure on how to read this info correctly from the graph.
I know i'm going to have to just treat the room and see how it goes but i'm just one of those people who like to try and understand things a little bit more...
If you or anyone else can give anymore on the subject that would be great.
Thanks

What I'm saying is that a room like yours should look much worse than that. I would expect a couple of deep nulls and a bunch of comb filtering in the mids. To read the plots you posted it looks like your room is nearly flat...it's within 6 or 8dB of flat almost everywhere. Really, *really* good rooms are +/-6dB...most non-purpose build rooms can expect to get to +/-10dB or so...that's very good. That's what I meant when I said the plots didn't look realistic. That, and the fact that the waterfall conflicts with the 2-D plots in a big way around 60Hz.
