Are exotic speaker cabinet materials overrated?

I remember a slide deck from Focal on how they aligned their engineering with marketting and sales.  Among the attributes they listed as important was "Sense of modernity."  

The idea that you are buying high tech as opposed to old tech.  It's an important sales tool, and in addition to cabinets applies to drivers, tweeter types, you name it.  No one wants to buy version 1 when version 4 is out. 

Having said that I think wooden cabinets, properly braced, are just fine. 

As you move up in performance speaker designs incorporate more and more aspects of materials used in the product. The designer must carefully choose materials... from the magnets, cones... etc. Ultimately to squeeze out the maximum sound quality the absolute rigidity of the cabinet becomes crucial... hence using exotic materials. Exotic material become more common as time goes on... so using them seems inevitable. 

A friend of mine has heard the exotic and expensive plinth that Linn came up with for their turntables... and commented that sonically it is superior.

Baltic Birch Plywood is amazing. It is probably the very first "composite" panel. which makes a huge difference in sound.  

When I was young and dumb I thought heaver speakers "had" to be better, remember when there was talk about concrete speakers.

My investigation of Resin Impregnated Densified Wood Board, which is the material Linn uses for their Plinth. 

As a material having been evolved as a design extends back near 100 years. Similar to Thermoplastic and certain Alloys. 

The most recent productions are offering assurity the materials remain stable across a range of exposures in a host of environments. 

When such materials are selected for use for Audio Purposes and are a material used by a Brand with a broad exposure. Such materials become exponentially expensive. 

A Board of Resin Impregnated Densified Wood of a Depth to suit a Periphery of a TT's Plinth, which when cut would produce blanks for 10 x Plinths is approx £2.5K.

Machinging and Finishing at approx ' £250ish.

In relation to a certain Brand, approx' £5K becoming £80Kish.

The same material used for a one off Speaker Cabinet Design as a 25mm - 32mm Thick board at 2mtr x 1mtr will enable 2 x Boards to be purchased at approx £2K.

Board Cutting - Rebating - Assembling will be close to £800 is complex with multiple cuts and parts assembly. 

Speakers from widely exposed Brands using this material type, have their cheapest in the range with this tye of Cabinet construction with a Veneer Finishing starting close to £50K.

I have done costings very recently for a new Speaker Design I am committing to, as an End Game Speaker. 

I fail to see anything that exalts this material type, to being more than what is already known widely, which is, as a material, it adapts itself very well for certain roles within an Audio design. 

@sounds_real_audio  - I am a big fan of composite materials, both in cabinets and speaker drivers.  I've always found mids made of composites, from a variety of vendors, sounding more clean and natural.  The resonance damping effects are real.
