Someone at the AVS forum named John Ashman has posted that Axiom speakers are bright because the aluminum midrange material resonates at the high midrange frequencies (where at 3KHz to 6KHz there is a slight peak anyway).
He says this is why Axiom's are considered "bright", because the tweeter isn't crossed over low enough to cover the resonance of the midrange cones.
Is any of this true? Also, wouldn't a spectral decay waterfall plot show/disprove this? I wonder if there are any available of Axiom speakers.
