EQ with REW: am I doing wrong?

[webzeb]

Hello,

Below are my left and right EQ settings:

Above 200Hz, I use Spinorama.org EQ settings.
Below 200Hz, I use an REW EQ built from measurements. I'd like to make sure I did right and optimize.

Thanks!

Fred

Room:
14sqm bedroom

Warning: furniture incomplete and not at scale!
Besides, bed is actually centered to the speakers.

The loudspeakers centers are about 1.63m (5'4") apart.
I'm listening from my bed, about 2.60m (8'6") away from the loudspearkers front faces. My ears are approximately at tweeters height.
The loudspeaker are only 11cm (4" 3/8) away from the wall; unfortunately I cannot do much more without affecting the circulation in the room (distance between the sideboard and the bed is already pretty narrow).

As you might guess, the wall is providing a lot of gain in the bass. Plus the speakers are exciting several room modes, in particular one @50Hz.

Listening setup:

1. WiiM Ultra
2. Hypex NC122MP
3. Wharfedale Linton Heritage 85th Anniversary

Measuring setup:

• Mac connected to the WiiM Ultra via optical
• REW v.5.40 Beta 132
• MiniDSP UMIK-1 with the 90deg calibration file
• Level of about 72dB (with a single speaker) / 75dB might be my maximum listening volume, often lower
• Separate measurements for Left and Right
• 5 positions measured (head position, then 15-20cm (6-8") shifts left/right/forward/backward), averaged (RMS average)

After a listening session, the results were not convincing at all !
It was lacking bass and something felt 'off' in the bass and low midrange.

Autocritic:

1. I should have applied an LF rise.
2. I think (correct?) should have avoid corrections these "mini corrections" with high Q value in the 70 - 200 Hz range
3. I should have set an higher LF cutoff, matching the speaker slope.

So, I came with:
Left is neat (I think)

Right I'm puzzled by the lack o energy between 70 and 140Hz. I guess it comes from room asymetry and some destructive reflections...

advice ?
