Treating our room. Part II
 
Last year, there was a first step in getting our room acoustically optimised.
You can read about that here:

https://www.audioaficionado.org/showthread.php?t=38497

After Ben's first visit, we ordered the panels and small blocks he carefully chose.
Something went not quite well, the order that arrived in The Hague proved to be the wrong one.
Then there was a very serious delay in the factory.
But finally the panels arrived at our house a couple of months ago.
I placed the small blocks in the corners (and I managed to do this in an incorrect way! :D), and the red panels in the fauteuils, and made an appointment with Ben.
What we also did between Ben's visits: placing a thick Nepalese handknotted carpet on our wooden floor.

And so last month Ben came!

I told him we already noticed some improvement: less echo, a considerably quieter room.
In fact, I was expecting some further improvement with his second visit, but no miracles.
We would still remain stuck with our glass wall on the left side, wouldn't we?

We started by measuring the first reflection points.
I sat down in the sweet spot and he told me what to do.

Same thing on the other side.
Because of the window, we knew the panels could not be placed in the 100% ideal location, but it would be very close.
Then Ben started measuring where the magnets were to be glued:

Up goes the first one:

With each step, the moment I thought: "Now it is perfect!", Ben went a step further in meticulously adjusting.

Positioned right next to our old Pioneer 60".

Now the next 2:

The 3rd panel:

And then placing the small block as it should:

The left side, the same procedure.

The system with the panels simply attached with the glued magnets allows you to adjust in a later stage (we are considering a 4K 65" TV!).

99.9% horizontal is not enough!

Second one on top of it:

Then the third and some final small alterations to the position:

Time to listen!

http://www.metazahren.com/photograph...e/IMG_5644.jpg


We started with a couple of albums from the label Ben has bought, see trptk.com
Check it out, it is fantastic!
I'll try their 5.0 downloads soon, but here we listened to the "simple" CDs.

For example this one:

https://trptk.com/wp-content/uploads...sible-Link.jpg


I can tell you, it was not simple, at all!
My criterion for a good concert is: I have, at least, shed some tears.
Well, hearing Maya Friedman and Daniël Kool playing Fratres, an Arvo Pärt piece I know so well, moved me to tears. Many.
Ben noticed and was visibly happy.

What a massive difference these 6 stupid pieces of plastic made!!
Well, they're actually not stupid, they're even attractive.
They're installed now for 5 weeks.
Mostly our guests don't even notice them.
And some people have asked us if they're art objects...

bart 09-02-2018 07:11 AM

So there we were, the best sound ever in our room.
I thought by then, congrats Ben, a job well done!
Ha, I didn't realise we were not even halfway the work...

Ben started again moving the right speaker, mm by mm.

He used the same track from Rebecca Pidgeon again, "Spanish Harlem", over and over.

In the sofa, back on his knees, back to the sofa, back to the right speaker:

Each time a subtle, but noticeable difference:

He says the Vivids are truly excellent speakers, but their woofers on the side make it a bit more difficult to get them ideally positioned.

It took us almost an hour for the right speaker to fully satisfy Ben.

Then we did the left speaker.
Only some minor adjustments were needed.
Minor and Ben: that still means 20 minutes! :D

End result:

Like I wrote before: the best sound ever in our room.
With these final speaker adjustments everything fell even more into its place.
I didn't know this would possible in our certainly not optimal room.
The first visit gave us 4 dB more bass, a better soundstage and more depth.
This second visit gave further improvement on all those points, and made the music much more real, as in: really in our room.

Thank you Ben!
This costed me as much as a couple of good cables, but it brought an improvement not even a 50K source would be able to offer.
