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

Phusis,

Neutral sound is of course subjective, however, the majority of loudspeaker designers seek to reduce resonance as much as possible or lower it to frequencies where our hearing is less sensitive. Solid woods don’t suppress resonance nearly as well as composites. An open-baffle design is far more logical than a tonewood box if one wants uncolored, true-to-the-source sound, with little to impede the behavior of the drivers. It’s also worth noting that cabinet resonance is usually heard as distortion - typically a grainy midrange, not something pleasant and complimentary to the sound of the drivers.

If someone wants a speaker that excells at reproducing the sounds of a violin, then certainly, it might make sense to use solid Spruce. Speakers from the likes of Viking certainly don’t sound neutral to my ears, but I’m sure they’re a perfect fit for some listeners.

I suspect some here are simply operating on the logic that MDF and plywoods are inexpensive, therefore, they must be an inferior choice. This might be true if discussing dressers or coffee tables.

Please note, Magio STARTED their speaker manufacturing business using plywood for the cabinet . MDF is as dense as plywood and inert enough to adhere veneer without future movement. It’s inherent stability combined with bracing creates all the stiffness necessary for any speaker enclosure. Drivers are tuned to the box, therefore if aluminum were used, as it is stiffer, and more dense, the driver types, as well as other design components, will be necessary for tuning the sound. Finally, few can afford a 200,000.00 pair of aluminum billet machined speaker so it hardly matters if aluminum is a better material. I listened to a magico system, m project speakers, and my guess is that system was in the neighborhood of 350,000.00. Frankly obscene, however, after 20 minutes of listening, although the aluminum speakers had a provocative sound, they were very fatiguing to the ear. All sweetness was gone. The difference between theory and reality!!

Listen to my Q3s for hours and never get fatigued.It depends on the wires which should be copper and the electronics it took me years to get them to sound my best.Oh well everyone has a Magico negitive rap.Enjoy the hobby!!
