Which material sounds better for speakers construction? Wood, Ply or MDF?

Back to the car at the stoplight with the music blaring. What I hear is this horrible distorted bass, a result from the back of the drivers getting the whole car excited and actually increasing the volume because the car now becomes a huge driver. 
This happens in speakers as well, get the cabinets excited and the room goes crazy and out come the bass busters. 

With monitor speakers due to the smaller cabinet size there is far less resonance of the box. 

Big speakers big problems. Cabinet materials that have a low resonance
are slow to eliminate them. So they store them and release them slowly thereby smearing the image. This is a fact and widely recognized.

Give it up dude, you obviously have not the slightest understanding of speaker physics. I'll await your reply with a claim of BS credentials.

@helomech Thanks for the informative reply.  Clearly you have found the items that work best for you in your room and for your musical taste.  As a former dealer, THAT WAS JOB 1 for us!  I suggest the boxless speakers only because we had much success with them and when A-B comparisons were made in our shop, they came out best.  Remember, this was in the '70s-'80's, so life and speaker technology  has improved dramatically since then.  I have seen $200,000 speakers for sale for homes...no comment.  Interestingly, I have noticed that many manufacturers are either raising their speakers on stands or designing them to be 6' tall.  I wonder where they got that idea???

Finally, a listener is NEVER WRONG!!!  You like a, I like b.  If we all liked a, life would be boring and only one company would make speakers, not over 300 at any given time.  I love the hobby for many reasons...some because I am retired from the business!...and respect everyone who is involved from any perspective.  It is a great hobby with music at its core.

All I can suggest is that you find a super-high-end dealer in your area who has the latest 30.7's running in a proper set-up and give them a listen.  Of course they are ridiculously (to me) expensive, but seeking the best and then buying what you can afford that gets you as close as possible is what the hobby is all about, IMO.  I hear you loud and clear that you found better than the 1.7 units.  Possibly the company has heard you as well and has figured out how to fix that--at an outrageous price.  Then again, that is the way of the world.  Race cars pretending to be daily drivers cost a bundle but don't do any better getting you from a to b than cheap cars.  But a prancing horse on your car costs a ton more than a bow tie!  Enjoy the music...

Cheers!

Laminated bamboo is the best sounding loudspeaker cabinet material I've heard.
My Bache Audio speakers have 3/4" bamboo cabinets.  Devore Fidelity also uses bamboo. 

It looks like my pick is also aluminium. Heard many designs sounding superior. Genesis 7 is one of them
