Ahh, if you now look down to the specs thread below, you can find (presumably) everything you need in the links provided by Eric from DrD. They are detailed in the pdf of the impedance plot. Now all we need is someone with the ability to run the sheets. I'd like to try an MLTL by itself, and then maybe with (I know, "single driver forum") a ribbon tweet to tame that high frequency rise, ala Griffin's JX92S-Aurum Cantus MLTL. - Pat
