RE: Danny Richie of GR Research VS Magnepan

I just rewatched the video. DR states he brought the low end down with an inductor on the bass/midrange driver. I don't know how anyone could miss that ;-) .

The 1.6 comes from the factory with a parallel x/o, the 1.7 with a series, correct? DR says the 1.7 has two elements in parallel on the tweeter---sort of a dual voice coil, he says---with a resulting 1.9 ohms impedance at high frequencies. To raise that impedance, he suggests rewiring the two elements in series.

I know some prefer the 3.6 to the 3.7 because the .6 Maggies have a parallel x/o, which allows bi-amping with an electronic x/o, unlike the series x/o .7 Maggies. Given the price of the 1.6, that may not be as common with them.
