Finally after some months of designing and planning, I've put glue to wood and started the build. Fun project...deciding on final colour....probably red like this image.

Have routered a channel into one of the slices to house the cable.
Also created a ribbed wall at the back of the comp chamber to try and eliminate the need for any felt or wool inside. What do people think of this approach?
See the start of the build here -

Driver initially to be used is DX3 Lowther.

Very elegant. Not too big but gig enough.
Whist I don't know about the sound properties of the see through sides it shows off the work nicely.

Not too big? 1400mm tall...and weighs close to 80kgs each. I now need to add a couple of braces inside the horn to complete the build. The weight of the larger section below the comp chamber is hard to work with. Next time, I'll design it with that section having a large cut-out...then I'll add wadding to the cavity.
The clear sides are 25mm thick...so I'm very confident of the accoustics.
The aim of the speaker is to create a visually attractive speaker, with great audio properties. The horn dimensions are close to the Dallas II.

NICE!!!!
I always wanted to do clear side so you can see the inside. But wondered how much that would effect the sound. Can't wait to see those finished.

I was wondering how the rib idea could be incorporated in other builds.
Often, I have left the cabinet empty at the beginning and found there is a muffling with many stuffing products.
What is the length of the horn path?

Horn path is 2.6m, mouth is 70cm x 30cm. WAF is high...especially if the W can choose the paint colour. Surprisingly, even at 1.4m tall, the speaker doesn' really look large. The width is 35cm.
I'm also working on a curvy Bruce. It will have the same (but more) fluted/wavy sections inside the comp chamber....all at differing angles and 'wave' sizes. I'll post a pic soon. Have been talking with David D on this.
No band saws here...all CNC machined on an industrial router. Computer cut dowel holes ensure the slices all lign up well. I just dowel, glue, clamp, sand, paint and fix sides. The acrylic sides are German made...very good quality. The routing pattern is ientical to the internal slices, except for the 'legs'. The holes in the sides are computer machined and counter-sunk and match the holes where the dowels go. This way, I'm screwing the sides into the dowel wood...not MDF.
I'm also going to build this speaker using varying colours of hardwood slices. A bit more expensive...but should look unreal.
A bit like this pic.

Just picked up the acrylic sides. See here -

Not a very good photo, sorry. The machining company did a good job polishing the thick edges. Looks like glass....completely see-through looking edge on.
Heavy buggers...probably 15-18Kgs each. The total speaker will weigh 75Kg each. Probably won't bother with spikes!

One side all glued...the other I'll finish today.

DX3 drivers ready for installation. Cable routered internally worked out well.
Getting close...
