ATR built by Sjaak/Holland
This evening, I was able to listen to the ATR.2 (
weighting a solid 18 kg à piece !) for the first time,
frankly I couldn't wait any longer, because the
cabinet still needs to be finished in terms of making the
round edges and painting it in high gloss Bordeau red.
Which is a lot of work as you very well know ! The first
impression is one of being 'taken' by the sound. One
of my cd's to check a speaker's capacity is the
soundtrack of the movie "Himalaya" by Eric
Valli. The second track start with this amazing Tibettan
drum, which sound with my Premium 11 just good, but with
the ATR2 the outroll of the drum - which can be felt in
the chest- goes much further and deeper, the next track
is a true test for producing a clear voice, and
sitting in the middle of the speakers suddenly the male
singer starts to get 'lose' from the speakers and it is
as if he stands right in front of me and automatically
opened my eyes to look. Unfortunately it's getting late
and I don't want to wake the up the rest of the family.
So I have to wait until tomorrow. It will be difficult to
remove the speakers and pick up the finishing job ..... .
Anyway a very fine first impression after one month of
work. I have taken loads of pictures so in time I will
send you the best one's with a few remarks. Above all I
want to thank you for the idea for this project and
your personal support in this.
Best regards, Sjaak.
After having the panels sawn, I milled in the side panels
a 4 mm deep groove to fit the brace.
Glueing three sides at a time saves time, but
youlll need a bunch of clamps to keep it paralel
Apply the 4mm bitumen and the BR pipe .
I dont trust the self adhesive bitumen so I use
contact glue (Bisontix)
on the panelside to make sure it doesnt come lose.
The BR pipe is a drainpipe of Ø76mm.
An old adjustable hole-cutting divice is able to make
holes with great precision( ± 0,2).
Home made circular milling device
with gauge to adjust the depth.
Second stage of construction, for which I use 1-component
Tweeter cabinet with bitumen of
which I had plenty, and remembered Troels statement that
these speakers cant be spoiled enough!
Ready for Prytexor egg-crate , being cut on
45 degrees to make a nice fit.
Filter with the three bombs of Superior
PS: As you can see, the layout of the filter is differend
in order to fit on the bottom of the cabinet.
Later I can provide the Making of the filter
How much courage
does it take do remove the speakers and give the cabinet
a nice finish?
They look mediocre but the sound is magnificent!
