Ok, understood, at least somewhat. Are you suggesting that the S2 operates at the frequencies between 1000hz and 3.6khz? I am not insisting upon using the driver at the frequencies that I was initially suggesting; far from it, actually, as these were simply a hypothetical starting point with the purpose of eliciting the sort of information that you are so ably providing. I am not insisting on anything aside from excellent (at least, from my perception) results from a 5-way, largely spherical horn configuration, since it is this topology that has challenged my long-held cynicism about the capabilities of "high-end" audio. That this has already turned out to be so much more involved than I had at first thought is far from disappointing, as a matter of fact.
de Charlus, I think you have a slightly wrong perception of this conversation. I do not use S2 driver at 3.6khz but I use two 2 drivers below and after secondary resonance (1200hz) as I feel that correction of drivers by LC electrical resonators damages the drivers sound. However, I do not recommend using any driver in any range. If you pay attention during reading my site I very seldom recommend anything specific but instead I advocate a methodology to find your own answers. You looking for results but I do see audio as cookie cuter results but rather as a possess. You feel that 5-way, largely spherical horn configuration is very effective? I do not disagree. There are many passes to take and you might use any drivers you wish. Take a driver, load into channels and play with it. Slide the crossovers up and down, change slope and types, change horn loading and driver loading. Soon or later you will end up with the configuration you feel correspond to your level of objectives. If you wish to use the drivers that I know I might assist to a degree but if they are the drivers that I never used then whatever I say or think is worthless. It is however is not about the selection of drivers or their bandwidth but rather to understand what you want from a particular channel. Read the last sentence again – it was very important.  It is not so simple right the way to grasp what your objectives and expectations are. You might do it but generally it takes time, at least in my case. It would be nice if you fry to meet Jeffery and he will demonstrate to you a performance of a few drivers in equitable configuration. I do not know if he offers such a service. Without it I would get Upperbass and MF and do not do anything else unit I develop an acquired taste in the way how the drivers perform.

Yes, the issue of amplification is premature, to say the least, but it resulted from a conversation that Jeffery and I had been having. It had always been my intention to obtain 5 pairs of commercial SETs (to me, it has always been the loudspeaker that has been the most inherently disappointing element in the audio chain, although each element has its bugbears) such as Lamm ML2s or Shindo Labs Lafons to power the drivers, but Jeffrey seems to favor the custom route, and you seem to have arrived at superior results through your own efforts. Any route other than this appears to be the very Pandora's box that might result in the "years of refinements" that so may on this thread have cautioned against, but that in itself does not deter me. Ultimately though, however long this takes and however costly it might be, I want to do this only once, sh to learn as much as possible in so doing, and wish to be content with the results for the rest of my life - this is how invested I am in this process.

A custom route is fine but do you know what you want?  Tell me: do you want to driver your MF channels with AD1, RE604, or PX25 tubes? How you would like to load them? How would you implement the filter in the amps if you do not know what filters they would be? How you preference of the amplification would change in context of associated channels?  How much power would you need?  Can you drive S2 and ALE drivers from the same amp? I can ask you another 100 questions that would impact the design chooses for your DSET but neither you or Jeffery or anybody else for that matter know the answers. It is not about the selection of brand or DIY vs. premade amp but rather about tailoring your amps to the need of your acoustic system, non existing acoustic system I have to say.

One more thing, If you deal with Jeffery then you can explore one more direction. Jeffery is close associated with WE people and you might explore their drivers. Not all WE driver are interesting but some of them are. You might look at Western Electric 594 drivers with better concentric phasing plug or the contemporary Japanese GIP equivalents. I did not see or heard of any worthy or serious installation with WE drivers but it does not mean that it might not be made. The people who experiment with WE are no different than the people who excrement with ALE/GOTO/YL drivers – a lot of snobbism and pretentiousness but not a lot of actual results. Still, if you can stomach to deal with them then you can fish something in the murky water of contemporary proper WE application.
