Hi Troels,
Started First week of February 2019.
Found a supplier of a few Baltic Birch sheets here north of Adelaide SA.
When I visited them, they thought I was just looking to screw it to the
walls of the house, and should find a retail supplier! They showed me
light timber with a few mm of birch on the outside. When I said need all
100% Birch, they changed their idea and allowed me to buy the sheet of
100% Birch I required.
Finally, had the Birch in the workshop. Have never cut sheets for
loudspeaker, decided to cut the Birch 90% square instead of 45%. Took a
day to carefully cut the Birch for the right sizes, and make them the
right thickness for the double front panels and the inside, and then
angled the front panel with the bass area. Put them together building
the speaker box.
Then sorting the front panels. They were also built by the same Birch.
It is difficult to find quality MDF here in AU - most of it had high
formaldehyde etc and wouldn't have it in our house. Used the router to
make the sizing for the speakers after testing on some other timber.
Took some time to get screws to close the front panels, eventually
bought them from China because couldn't find the right ones here in
Australia, and any I could find were too expensive.
Decided to varnish the box using gloss varnish, and matt varnish on the
front panels. A few people here has looked at it and liked it. The gloss
is very shiny!
Built the crossovers. Took some time, have never done anything like
that, but quietly and slowly got it built, soldered, glued with silicone
and some screws.
The next job was to install the insulation. Found some from a local
supplier Jaycar with AX3680 that has heavy. It is with barium in PVC
sheets. Glued them in the box and then filled it with the felt material
and the acoustilux, once the crossovers were built and installed.
Finally, the first speaker was done by the Monday 18th March. Took about
5 weeks to get it finished. The sound of these Ellam's are way better
than I thought and have enjoyed them every day since they were built.
The bass is more than I would have heard from smaller speakers. Very
happy with them.
Has been very interesting and happy, busy to build them. Happy to show
them on your Builder's Response if you are happy to do that.
Regards,
Michael
