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

Aluminum rings like a mutha!!! 

Wood...my Totem Cherry Forest Signatures Sound like a Stradivarius !  Fine musical instruments are made of wood.  Can you imagine a plywood, MDF or aluminum violin 🎻. Yikes!!!

@dave_b - speakers aren't the same.  Musical instruments are designed to resonate.  That's how they get their distinctive sounds.  Speakers, on the other hand, are designed not to resonate.  The less they resonate, the less of their own sound they have and the better they can reproduce the distinctive sounds of musical instruments.  

I’ve had the inert kind....sorry, but they do not sound organic and alive like real music.

Dave, have you heard all of them? I highly doubt it. Not sure what price ranges you are talking about, but I'd love to hear your conversation with Richard Vandersteen or Alon Wolf about this, lol.  Sorry, but you can't make that statement unless you have heard all of them.  I promise you my Vandy Quatrro's are plenty organic adn alive like real music in my room.  Plenty of speakers I've heard are outstanding and sound like live music and they are made of all different types of materials.

Totem are also nice speakers and I've enjoyed most of them at a local dealer as well as a dealer in NYC.  There is no best.  It's all design and implementation.
