    How is the Vas of a driver linked to the volume it'll give the flattest response in? I'm assuming there's a mathematical formula??
    The Adire website gives three "alignments", so how do you work out something like the EBS alignment for any driver? (Huge, with huge sound) [​IMG]
    Any other relationships between specs on paper and real-world building issues?

    Yes, but until you know how the specs are derived....
    Some that's not so obvious though is VC heating, BL and compliance distortion, and port non-linearity with increasing excursion. Few programs address these. Lspcad does, as do manufacturer's high zoot in-house design software. Don't know of any others, but I don't keep abreast of what's available. Fewer still address non-golden ratio cab dims and how it affects modal distribution.
