Extremely Nice DIY Fullrange, Center, Rear/ATMOS Set

WLDock

This is one of the nice's DIY speakers sets one will find. The front towers are 3-way and use ScanSpeak tweets, Skaaning mids, and two Skaaning 10" midbases per tower. The crossovers have a lot of high end Mundorf components. The rear towers have built in ATMOS enabled drivers.

What a beautiful set of speakers!

Yep those look awesome for sure! Didn’t check the thread, but did he say how much he invested? Those had to be pretty pricey...

very nice! A couple of those inductors look like they could double as doorbell transformers.

Very expensive DIY project! I calculated about $6400 alone just for the drivers in the front two towers.

Words from the builder in the thread:

The front speakers costed approximately €12.000. This includes the outsourcing of the CNC work.

I think I need to explain something about this project.
I have made 7 speakers in total that are powered by 9 amps (well 11 to be exact, as I am bi-amping the fronts)
The 3 way 5 speaker fronts
The 2 way 3 speaker surrounds that include a 2 way built-in Atmos upfiring
The 2 way 3 speaker ceiling speaker
A 3 way 4 speaker center speaker

The CNC part was quite a challenge.
After we glued the first 6 baffles (2 big ones and 4 small ones) and went through the CNC process and the next day the layers came loose. Something went wrong glueing the 13mm panels on a vacuum table. The second time I glued them under a 30ton press. That proved to work but the CNC machine caught fire due to the drill getting blunt.
I spent in total € 1000 for just the baffles CNC without material

As we do not have a wood-shop with the tools and the space to make 6 speakers more or less at the same time I made a deal with a local wood-shop.
(i saw in your line array thread that you have quite some space to build something)

For a reasonable amount of money he delivered the MDF material and did all the CNC work for all parts except the fronts as that needed a 5-axis CNC. At the same time we could use his place in some evenings and the weekend to put it all together, glue, sand and mount the parts.

Of course the parts are expensive.The drivers (see below picture when they all arrived) Audio technology, the beryllium Scan-Speak tweeter and the Mundorf top of line parts add most to that total amount.

Even the feet were €35 each on Ebay. Stainless steel rods, Technocell dampening. and €2100 for the Walnut side panels (4 speakers) also influence the cost significantly.

I must admit that when I started I had a smaller budget in mind, but if a project like this takes over a year you don't feel it that much.... haha.

There are several things that as an adult I hate about my high school years. One is having wood shop and electronics classes always opposite the band classes, and I knew I’d major in music from the time I was offered a scholarship in the 8th grade.
