    alright, seriously, is anyone here reading this stuff? if not, I won't bother to post links. There's been zero discussion on any of the tests here. Can't help but feel it's a waste of time to post.

    Other than the last couple, I haven't been able to see any of the data because I can't access DIYMA.

    The anarchy surprises me a little bit with the apparent offset. The Bl curve isn't as flat as I'd expect but doesn't seem to disagree with the other data.

    The Scan is impressive. Very symmetrical and a nicer Bl curve. One thing I wonder about midbass drivers and subwoofers in general is whether it's better to have the very flat BL across ~70% of the usable movement of the driver, and accept the consequence of a very sharp decline outside that range, or to have a broader smoother Bl curve that is never as flat, but also never drops off suddenly.

    It's nicer to have a very linear BL and then drop sharply before xmech. This way you get the linear operation and you also get a built in motor brake. Same with the suspension. I'd get a perfect corner if I could. Imagine the distortion does not increase with volume due to a highly linear motor. You put more and more power to it until it stops giving you more output. The BL would drop so much it would prevent you from jumping gap. Perfect speaker imo. The only problem with very linear motors is that they lose some sensitivity at low excursions compared to traditional overhung. Worthy tradeoff imo.
