However, I must say, I have a lot of trouble accepting the idea of redundant drivers.

Yes, it dose not sound attractive to me but it is not the redundant drivers but one main driver and another at minus 9dB driver, sort of the “colorizing driver”. It dos not really emits own sound but rather slightly tone up the main driver. It is hard to believe but if you sit in my room it would be easily demonstrateable….

Do you really feel that it would be desirable to inject tone up in the range where you have the S2s working?

It is NOT necessary but it is beneficial. I started to do it bit because the S2 deficiencies but become the certain Red’s tonal inflections that I do fount appealing (in a small well quantifiable doze)

My own Mid-Range arrangement is based on that of the Macondos... Listening to my own system (I have enough of it done now to make some observations), I can say that there are two elements which bring significant tone to the overall perception:

1) The AK151 Mid-Bass drivers, even without horns.

Absolutely phenomenal driver, nothing can touch it!!! If you corner-load it in a right room you will have the upperbass that will be EXTREMELY difficult to beat. Sure they you would need to time alight it with the rest of the system that should not be in the corner.

2) The pair of 18" Lower-Bass drivers in sealed boxes (a sort of effortless bass with very good tone... A nice surprise, as I had to buy them without having heard what they could do).

Hm, the “tone” subject in context of the lower octave is VERY different subject …

Obviously, neither of these directly add tone anywhere higher up than Upper-Bass... Nevertheless, they may be affecting the way the S2s channels are "perceived". In my case, I don't feel that the S2s would benefit from more tone. However, if I could hear your experiment, I may change my mind.

You can’t not imagine how good the S2 with AK151 if they properly used (room). I keep some of them in my storage and I would LOVE to found some use for them….

What diaphragms did you finally settle for use with your S2s... Plastic or metal suspension?

It never changed. For MF I use the plastic suspension and for Fundamental Channel the metal (wich is not critical)
