Why are there so many wooden speakers?


I have noticed a problem within the speaker industry. 99% of speakers that come onto the marketplace are wooden, i.e MDF.
 
This is true of old speakers and new speakers. This is true of Dynaudio, B&W, Elac, Kef, revel, PMC, Focal, ATC the list goes on and on. This is a longstanding problem that has been deceiving audiophiles for decades and it requires a solution. 

The problem with a wooden box is that no matter what crossover or drivers you use, it will still sound like a wooden box. 
There is a limit to the sound you can get out of a wooden box so it is not possible to improve the sound just by using different drivers. Despite this, every year or two, the aforementioned companies put new speakers on the market claiming that they sound even better than what came before. In conclusion, we are being misled. 

I have no problem with MDF boxes per se. MDF is a good material to use. But if you want to make an even better speaker then you obviously need to use a better material. You cant use the same material and say you have made a better speaker. Thats false. 

Let's take the B&W 600 series for example. This is a series that has been going on for decades. 

Here is the latest speaker from their current series

There is no mention of what wood is used but I'm pretty sure its MDF. All they talk about is their continuum woofer and dome tweeter that goes up to 38khz. No mention of even improvements to the crossover let alone the cabinet.

I believe that this has gone on for long enough and audiophiles deserve better treatment. I don't know if a class action lawsuit is the answer but something needs to change.

That is probably one of the main reasons youre not happy with them

I'm a lot happier with my speakers than you are with your lot in life, Kenjit. 

Mine are made from cast iron, Jern 14EH, and are stunningly good. No colouration. They need a couple of subs, but give high end quality at full range in a small form factor for a good price.
Kenjit has a point, and he draws attention to an industry that charges, and gets, exorbitant prices for products that only cost a limited amount to construct. For instance, a local stereo shop has a system on the floor for $500,000. It is certainly beautiful to see and stunning to listen to. However, it doesn't look or sound $475,000 better than my system. I am amazed by the dollar amounts that get discussed for some things on this forum. In another post, we discussed our occupations with the most of us not having millions in discretionary income. How about someone posting a thread regarding cheap and simple ways to improve the sound? How about assigning a dollar amount for this discussion to around $300.00 or less with an emphasis on most improved idea that cost the least? 
800 series B&W's use an internal, labyrinth inspired construction to damp out vibrations and echoes.  Listen with something other that what Best Buy Magnolia offers.  The current 804's are un-listenable with the Rotel electronics used for demos.  I gave them several auditions to understand what was wrong.
I'M MAD AS HELL AND I'M NOT GOING TO TAKE IT ANYMORE!
Thank you Kenjit for bringing this important subject to our attention.
