Actually the frame is made using Multi-wood and acrylic, the top layer is multi wood and bottom layer is acrylic. Top layer is done with CNC Router and the bottom layer on CNC laser.
Thanks,

Magma,
The frame's cuts are done with CNC Laser and CNC Router.
It's not MDF, its Multi-wood a kind of plastic based material which is normally in white colour.

Where do you get multi-wood? Can you share some more info? Have you tied it with a router?
Please see more info regarding multiwood here.

Thanks. That link gave the marketing speak. Very interesting. But how is your experience in practice.
For eg would you ever consider making a cabinet out of them? Maybe 2 layers, ply/MDF on the inside and multiwood on the outside.
At this time i don't have an answer, because i haven't build a LS with this material.
But some of the advantages are:
1. We can apply water for sanding.
2. CNC Router machines can cut this material.

How dense is multiwood? If denser than MDF, I think it would be better than MDF for speaker cabinets. And even if more dense, I doubt the difference for small speakers would even matter. For larger speakers, I should think it might matter.
Am curious - why the question of building a layered cabinet with ply/mdf as the inner layer? What possible benefit do you see this having?

If the multiwood is anything like they describe I.e PVC polymer composition which I suspect it is
We can't use it in cabs
Plastic flexes for the same thickness
Can be used in cheaper ht stuff which it is already used in btw
In grills on the other hand it is a good choice other than plexi all the way
Which would turn expensive

Even if it flexes a bit, I don't think it would flex so much as to warp a cabinet made of this material. And IMO some flex will not generate cabinet resonances which is the bane of wood and the like. And resonance is what I'm thinking off when I said that Multiwood is probably better than MDF. My apologies for not being explicit.
Just found this:
Typical Density:
MDF - 780 Kg/m3
Multiwood - 575-675 Kg/m3

I was actually thinking of using this instead of MDF. Just went to the shop and took sample of 18mm Multiwood. What I personally feel is the material has lesser density and weight when compared to MDF.
But with proper Bracing we can use for mainly Bookshelf works and even for Floorstanders also.
I will be trying this for one of my project. We can only know when we actually do a practical work with this material.
So far this material seems promising, but as I said need to try it out and see the actual result.
Another advantage are:
1. It doesn't need any primary treatment like what we do for wood and MDF. It stays life time for sure.
2. Majority of the local CNC router shops will take up the work since it won't throw dust, like MDF and wood.
3. Getting a professional finish is a breeze since we can use even water on that for sanding.
4. Can screw, glue, paint etc. and also its a recyclable material.
The price for this sheet ( 8' x 4 ' ) for 18mm is around 5K INR. And 25mm is also available.
Sharing its technical data: Multiwood Technical Data l Multiwood Eco Friendly l Go Green with Multiwood
BTW, today able to do the bitumen treatment for the X-LS Encore build. I am sharing few shots below.

@bijinmb - how did you fix those bitumen sheets to the walls? Is there a type of sheet that works better than others?

It's self adhesive type bitumen sheet.

That looks very good.Can you share the source/brand.I need to damp my TT.

Sachin,
Please go through that bitumen sheet images, the name is printed over it. I bought that from a local h/w shop.

Hi Chandan,
Your cabinet work has started, I didn't got a chance to take the photo. I will post few snaps of WIP soon.
Thanks,
Bibin
Why is bijinmb banned???
I searched his posts this noon, could not make out if he posted anything wrong.
Did someone complain about something? somewhere... some...
