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


Im guessing they use mdf these days because its cheaper.

I laugh when reading threads like this.  It's as though there is an absolute or holy grail.  All materials have different properties.  All speakers have compromises.  

Designers figure out what they want for their sound and build/design accordingly.  They do a ton of R&D if they are large enough and will use all different materials.  They can do modeling and figure out most of it on a computer.  I think this is one reason the DIY groups started to grow again after they were kind of losing steam a bit in the early 2000's based only on what I've been told (I may be wrong).

Folks will find fault with all speakers.  We all hear differently.  I'm glad that folks who have Magico's love them, but to many they do ring and are fatiguing.  I feel that Wilson's and their polymers and choice of drivers lose much of the micro and macro details, but boy are they dynamic.  I love listening to Harbeths, but again, they too lack much detail, but man are they enjoyable.  All use different cabinet materials.  

I own Vandersteen's and I choice them over nearly everything I could possibly audition that was under 35k or so.  He went the carbon fiber way years ago from house made cones to the cabinet.  I also know that he 'auditioned' all the different weaves of carbon fiber that he could get and choice a specific on based on it's sound quality. It's a very expensive cloth as it's teh same one used in my ultra high end walking poles (I have MS and have poles to get around inside buildings when I can't use my rollator).  

the bottom line is that some will find fault wiht the sound of the Vandersteen 7's as they will focus on his compromises, just like I get fatigued listening to Magico's as he's lifted the treble to make them sound more open on top etc... (if you measure speakers, many of them are lifted up to 3db in the high end to give them a more 'detailed and or larger soundstage".)

Again, it's all implementation and compromises.  There is personal preference, which makes this hobby a blast, but no 1 correct answer.  
@ctsooner Magico’s as he’s lifted the treble to make them sound more open on top

Listen, you can like what you like, I am not about to get into a Magico dirt fight again, but some basic diligent of facts, not opinions, are needed.
It is actually the Vandersteen highs that are pronounced, not Magico (Plenty of measurements all over the place of current production models – you can start with Stereophile S5/Model 7). Vandersteen enclosures use of CF is minimal; they use a layer or 2 to basically veneered MDF. Vandersteen “CF” enclosures ring plenty; it is his pure MDF enclosures that are inert but, as the case with many “inert” cabinets, they are over-damped, again just look at measurements. Magico S5 THD measurements are the lowest ever measured at the NRC; rest assured, it will not be the case if they “ring”. Try listening with your ears, not your eyes, just because something is made out of metal, does not mean anything; does your car rings?

"Wasn't there a company making cabinets out of cast concrete?"

Maybe you are thinking of different brand, but early Hales speakers had concrete baffles. Paul Hales switched to MDF because of economy in creation and exporting the heavy speakers. I came across an Asian manufacturer making cabinets out of vases. They were trying to find US distribution. Nice people; I hope they didn't struggle too much before quitting the impossible mission of marketing it to US audiophiles.

MDF, if anything is ultimately practical and established. I have not heard a wood box speaker using Scanspeak drivers as good as what YG has achieved, and I welcome the variety and pioneering as MDF is not some panacea. 
RV is a measurement and science based engineer, I can assure you that the 7 cabinet is superior to the 5a in every way.
impossible to overdamp a passive component like a cabinet - you want to hear the Stradivarius or the cabinet ?
the 7 cabinet is a mdf  cabinet within a mdf cabinet with constrained layer damping ( he collaborate s with Michael at HRS, so my guess is that is is HRS supplied ( and you just know they are serious engineers ) and CF wrap cooked in an Autoclave.
in a previous working life I dabbled in advanced composite structures... running arguably some of the most advanced high technology composite shops on the planet- simple stuff like the Hubble optical bench, F-22 wings, 787 fuselage.....
easy stuff...
i can assure you it is more than veneer
now from a musical perspective, while I loved my 5a for many many musical years, the 7 mk 2 are lightyears on....

enjoy....
