Hi
I know this is not exactly a forum to talk about this, but I'm desperate. I have DALI Ikon 6 Mk II's, room as in the picture, amplifier is Sony TA-FB730 and CD is CD-S1000 by Yamaha. When I listen to rock like Dire Straits its is pretty good, but when try to listen to metal bass is like cut off. I checked phase, speakers are standing on spikes. I also heard my metal recordings on the same speakers in shop, everything was ok.

Try moving back further toward the rear wall about half remaining distance. You'll probably still have a null around 80 Hz, but everything below that frequency will be better.
Then try them farther from the rear wall. Part of the problem may be the proximity to the side walls.
Recommend downloading Room EQ Wizard (REW), then lay in your room dimensions (width x length x height) and the position of your listening position. The resulting FR plot will allow you to move your listening position and loudspeakers around and see the effects on the FR at the listening position. This will be of much greater value than trial-and-error approaches.
Spikes, etc. will do nothing in comparison to moving your listening position around to help your low frequency issues.

It is likely the room that is the problem.
As others have suggested, repositioning the speakers and/or the artifacts in the room may help. REW sounds like a good way to understand the root problem.
Analysis of the room's frequency response may help. You may need to add bass traps, which doesn't do much for decoration in the room, but may help level out the response. It sounds like your issue may not be solved by bass traps.
Dr. Geddes also recommends adding multiple subwoofers to a room to overcome bad room response. Two, three or more subs placed at asymmetric positions in the room do a wonderful job of evening out the room response in the bass department.

You need to have acoustic adjustments made to your room.
This is the single most important thing to improve the sound your hearing from your system.

Hi,
if bass drivers are positioned a bit away from the next nearby reflecting surface the time shift between direct sound and reflected sound could well be right in the frequency range 60-100Hz (cancellation/~180°phase shift).
Seeing Pics of that Dali I don´t wonder at all that You got issues in that bass region simply from reflections off of the bottom floor.
In that case nothing will help as it wouldn´t be an room issue but a matter of box construction.
I´m quite sure though that box construction isn´t all here though and that You suffer from serious room mode problems.
My own room is quite similar in hape to Yours, with a quite flexible wooden floor, and the ceiling seems to be ´soft´ also.
Without beeing able to -and not wanting it either- I cannot room tune with bass traps and similar bulky and ugly stuff.
That left me with only two measurements, heavy electronic equalizing and/or a special bass speaker that mostly avoids the severe room modes.
My solution is a high dipole bass tower.
I´m not sure if multiple Sub placed on the floor would have been able to cope with my situation, where the vertical modes were the most severe ones.
But it would have been my second test, if the dipole tower had failed.
Apart from one mode which is still detectable on a low and very acceptable level all the prominent modes that made natural bass unlistenable have been corrected for.
Now bass replay is exceptional clean and kickbass really kicks one´s A**.
I´m afraid that if You want keep Your speakers only electronic equalizing may help, as the space for different speaker positioning is very restricted.

Very much of the bass will disappear through the 3,9m window behind the speakers and result in a thinner sound. It would have been better if you had a solid wall behind the speakers. Also, remember that where you sit is almost equally important for the bass response as where the loudspeakers are placed. Try to move the chair a little around and see if it helps.
There can sometimes be many problems to poor bass and many solutions, but they would almost always involve some sophisticated measurements, etc. The only "universal" solution that I know of is using multiple subs. This can always be made to work. Almost everything else will be hit or miss.
All of the above is likely true.
But Multiple Subs?? in an 11' x 14" bedroom... Really?
I'd would try those speakers in every imaginable configuration possible and if that didn't work. Try entirely different speakers.(imo the best solution direction)
There is something clearly out of whack therein.

The smaller the room the more multiple subs are required for a smooth response. Large rooms don't need them. It is not about output, its about modal smoothness.
Two subs (plus some eq via MiniDSP) are far better than one in my 14 x 11 den. So far I have not gotten a huge improvement from the third one, but one of these days I'll move it around and try again.
One good thing - each sub can be relatively small and still rock the room when you have more than one.
