Interesting insight on the sum of parts aspect, but I only partially agree. While there might be the occasional "perfect" pair, I think people aren't giving enough consideration to how many parts make up that sum that is the Sextett. There are two different drivers, which make up the primary tonal difference between EP/MP and LP, and then there are the different baffles, that have a smaller but still significant effect on all 3 main versions.
Gosh, I really do need to get around to doing some detailed measurements on the Sextett while isolating the various factors, to see if there's a rational explanation for the variances, like I said I would. I could've had a field day with Tyll's measurement rig at CanJam, but with how long it takes to do one set of measurements, I wouldn't expect him to indulge me in doing dozens of combinations.
Ever got around to measuring, Fitz? I've seen measurements for the EP and MP, but I don't think any for LP...
A lot of people seem to be reporting that there's not a lot of difference between the three models, and then a lot of people reporting that there is a lot of difference. I've only heard one pair of Sextetts, LP, though even that only had one working channel. Based on that experience, the sound was somewhat bright and with lean bass. In description it sounds totally different than what people are reporting for the EP, for instance. Also, in description, it sounds quite a bit like AKG's other models from the late 70s on (K 241, DF).
What I am curious about is the combination of people reporting LP to be leaner in bass than the EP and MP (and presumably brighter), and Fitz saying that there were two driver variations (presumably one for EP/MP and one for LP, if I understood correctly).
From what I gather, the Sextetts were free field equalized, which I suppose kinda shows up in the raw graph Tyll measured for the EP. However, based on my own measurements, the K 241, which came out around in 1979, looks to have been diffuse field equalized to some degree. I could be wrong, but that's what the raw response curve looks like. The K 241 is a bright-sounding model.
So my question is, has anyone measured the response of the LP – and whether it looked more like a free field or a diffuse field curve?
