If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have ordered them back when Fane were still in business!), just for the sake of comparison when used in a 115Hz horn.

Well, you need to understand that my decisions to go for 16R Fane in 2000 were mostly argon decibels. Since at that time I was driving everything from the same amps I was concern that my upperbass horn would have the similar output with my MF horn. The Fane Studio 8 was born as a replacement of the default driver in the Avantgarde upperbass horn. I got the 8R initially and it was a few db lauder then my MF channels (I use many-many MF driver at that time for MF, including the AG own MF driver). So to EQ the things I do not use voltage dropping in crossover but I drove the different channels from different taps of my ML2. Then I went for 16R version Fane. When later on I when to DSET then the impedance of the drivers lost any significant as it always might be tuned by transformer ration.

Sort of on the same subject: I edited the last post I left back in the Living Voice thread; if you've not already done so, it would be interesting if you could comment on my assumption that Vitavox specified a lower R version of their 15" bass drivers in anticipation of the additional load (seen by an amplifier) once the driver is mated to a horn. It seems inevitable that additional physical load would translate into additional R as seen by the amp. Never mind that its likely no commercialized implementation of this driver loaded it to such an extent as to require the lower resistance winding.

Might be, it is hard to speculate. To do it I think it needs to be known how Vitavox intend to drive those speakers and this is the information that I do not have. I have seen a few SS Vitavox amps but never tube amps. I do not know if Vitavox was in tube amps business and I have no idea what amplification they uses in 50s and 60s for sound re-enforcement.  Those sound re-enforcement requires a lot of power – most likely they uses SS amps. I know Pink Floyd used S2 drivers and it was all SS amplification I guess. Still, I feel that in our home utilization we all those drivers to much, much, much more sophisticated degree that they even meant to be used. So, I recognize what they did back then and what their objective were as very much raw material and I do not take their initial intentions too serious.
