How about using the 6C33C for the low midrange-woofer, the 2A3 for the upper midrange, and the 45 for the tweeter? I suspect if each circuit can be optimized, that they can do their best within each frequency range.
Hm…. I do not think that it makes sense in your particular playback. You use Edgar’s refrigerator subs that use own LF SS amps (that use EQ of I am not mistaken), so you do not use the full advantage of SET LF sound. To construct 6C33C DSET juts for sake of upperbass driver doss not sound reasonable to me. Now, if you intend to drive you subs and upperbass from 6C33 then it is while another story. Then you might have 2-way DSET with let say 500-600Hz break and it might be an interesting solution. The key would be to found out what kind loading the refrigerator subs would demand and if the 6C33 will have enough power to drive the LF. It would be also nice if the upperbass would be OK with the same loading as bass would demand. Then you can go line level-crossover for MF (big advantage) and do not case about the power from your 2A3. Theoretically it possible to make a situation when the 6C33 and 2A3 would be driver from the same PS but it would be too difficult…
