"What is the sonic advantage of using aluminum for the box?"
Mapman to answer your question...and I'm in agreement with you on the
Avalons and other speakers.
Cabinet panel resonances are a significant cause of sound coloration, if using
aluminum enclosure there is better elements of stiffness, mass, and
dampness compared to MDF enclosures with heavy bracing and the special
resin dampening glues. Accordingly, this allows the drivers to operate with
clarity and dynamics. Yeah but what does that mean when I'm listening to my
main man Steve Jordan playing his custom maple snare drum. Magico does
not use MDF, the V3 and mini II enclosures are one-inch layers of extremely
stiff, laminated, 17-ply Baltic birch plywood.
I do like the approach for enclosure system design but can you tell the sonic
difference when AB. Which is Aluminum and which is MDF? I think it is more
about the unique tone.
Metal snares and wood snares have two totally different resonance I don't
think one is better...it just depends on the style of the recording and type of
music that fits.
