Default Need help in Acoustics!

Hi!

In the next posts, I'll put here 5 pictures of my room.
This first one, is a close take of my system.
The help I need is this: Is the position correct as the layout of the room is not square?

Thanks in advance.

Without knowing a lot more about the room & the response of the speakers only suggestions to try can be offered... and even if we had that info there would be a lot of guessing going on.

For room placement there is not a lot to substitute for move & listen.

The 1st thing i'd do is pull the speakers out from the wall more.

Of course the SAF factor plays a role and often the "approved" placement won't coincide with the best sonic placement.

The couch against the wall can also be an issue too....

Ok!

Some specs:

Check this page

It's in my site and if you click the speaker design, it opens the diagram.

It's a sort of transmission line and it has a rear output at the bottom.

It has Audax speakers.

I'd class it as a Daline (i'll have to put a link on my projects page).

The critical specs include FR, dispersion, the reflectivity of the room and such. Without a lot of kit & computer modeling software, moving stuff around and listening is still the best route.

Pedro,

Correct me if I'm wrong, but the only sound absorbing thing I see in that room is the couch?

That's going to be an increadibly bright environment, and you will have a VERY difficult time getting it to sound right. Often times the long decay times of this kind of room show up as a very forward midrange/high frequency response. See if you can't add a throw rug, curtains and maybe some absorbtion behind the speakers. Potted plants in the corners may work well too...
