new project.

Are they? Please check with a listening test.

https://www.audiocheck.net/audiotests_polaritycheck.php

The connection of all components and the filter are connected by a pro and are biwired.
The speakers were tested at another location that had been adapted and they played perfectly there with enough bass.
Have already tried a lot but it is purely up to the space itself.

Frank,

do you tried closing the bass ports complete too?

it's possible to show your measurement?

We tried that first and it wasn't good, then made the gate from the back and it wasn't any better either.

[papabuell]

Here are some measurements.

[Lebrichon]

Thank's for the measurements. They clearly show typical room acoustic problems and low bass between 35 - 50 Hz and 65 - 100 Hz. It's easy to imagine that you miss deep frequencies.

Unfortunately, I have to say, that if you install woofers with more bass, the result will not get any better. On the contrary, the bass will become extremely loud on other places in the room than on the listening position.

In my opinion, there are the following possibilities:
1) Change listening and/or speaker position. For a small test, you can move the speakers a bit, to check if the bass response will get better. If the new speaker position is not acceptable for your wife, you can also install some rolls underneath the speakers to move them any time you want to listen to good music and place them back, when your wife is at home.
2) Install an additional subwoofer, which can also be a hidden one (like behind a cabinet, underneath the couch or disguised as furniture)
3) Invest a lot of time and calculation into room optimization, which is not easy for such deep frequencies. Of course, that can be an optical problem because for a hearable effect, they must get large.

Also "pros" can make mistakes. When i change connections speaker - amplifier, i always do this test.

But i think, lebrichon is right, its the room and position. If you add an aktive subwoofer this will fill the dips in the bass. If you buy an Antimode, the frequencyresponse is automatically better. If you do this, the Sub can be placed in a roomcorner behind your listening position. 30 liter, closed cabinet is enough.

additional
4) not buy anything, try APO-EQ first!

Jungs, ihr habt recht, der Raum ist scheiße:



und mit SUB

I have already tried to place a sub but this is not accepted by the woman.
So there are not many choices left.

I believe more than 10 different measurements have been made with speakers to be moved, both in width and in distance from the rear wall.
These measurements are the best result that could be achieved, the others are even worse.
A sub can help, I know that too, but I don't just decide here about my wife, she's also there.
A high-pile carpet would also help, but with 6 dogs in the house, no solution either.

Here are some photos of the layout of the room.
Photos are drawn behind the sitting position.

Hey,

i got no real expertise in matters of acoustics;

and only in case you didn´t try that yet, of course ;

but when looking at your pictures of your listening-layout, my guts told me ,
that it might be worth a try (and easy to do) to exchange the position of the speakers with that of those high-column-boards you got there standing
to the left and to the right of your low-TV-board.

Leave a bit of room for the speakers to the high-column-boards which would be standing on the outside then, and, if possible, put the speakers even closer to the wall.
Then check again, and try to variate the positions of the speakers and high-boards slightly in order to see (or hear) what changes you get with that.

Best wishes

[papabuell]

Hey, thanks for offering another option but this is only possible if you're single, hahahaha.
Have already discussed it with the wife but not yet.

[JAL]

I get your point....

[papabuell]

I also presented my problem with space and bass to Visaton themselves and they suggested the EXPERIENCE V 20 to solve the lack of bass.
What is your thought about this.

[walwal]

The Concorde Mk3 or Concorde WG sound better and can deliver more basspower than the Experience. But are more expensive, All 3 are D'Appolito, they sound only perfekt, when you sit at the hight of the tweeter. I would prefer speakers with (built in) an aktive Woofer, so you can equalize the roommodes. But then you have to build your own crossover, are you experienced for this?

You could also build two aktive subwoofers als stand for 2 smaller speakers on top.

However, the bass should be aktive and equalized, if not, you never will be satisfied.
