Thanks Romy.
Sounds like tweeter on top will be best approach in my situation.
The room is a good size and shape - 23ft x 15ft with 9ft ceiling . Plenty of room above.
As you say the 288 on Azura does go to 12-13k OK with some beaming - almost enough really .
However I was thinking of bringing the tweeter in approx 8k, but could try higher, eg 10-12k as you suggest .
Some experimenting will be required. Have you evaluated tweeters in isolation with 1st/2nd/3rd slope to determine best approach, or have you generally had to integrate into the system to be sure ?
Amps will be SE custom-built . 2A3 or 6C4C for the bass/mid ; 2A3 for Mid/HF and prob 71A for tweeters .
Bud Purvine most likely making the iron .
There may be some novelty in the dividing/crossover arrangment , that part of the circuit is interesting and a number of options are possible .

Full system will not happen quickly, but I do hope to get one side working with Tractrix and Azura and suitable amps/crossovers within a month .
