I like both of your wishes but I would go with Henk refurbished Apogee FullRanges. Scintillas I already had
After re-reading this thread, I think I would invite @kodomo to my place for an extended period of time and let him go wild with a passive multiway horn System like his
If possible with Plasma horn tweeter. Are they able to do 100dB?
The Subwoofer could use the room over the winter garden/TV room (should be a few thousand Liters).
Thanks Cristoph, I am honored! You are not alone, some other friend has been pushing me to build him a speaker as well and I will do that rather than doing one of my own projects this winter. I have already started. It is different than mine, still horns of course, from 80hz to 20khz. I will share it when it is done This is my hobby and my actual business is taking a lot of my time. Thank god my winters are a little more free... I had some side projects I wanted to do for this time alignment issue. A system with actuators that moves horns backwards or forwards to match impulse rises. Complete with its mini pc, dedicated software, measurement mic. Built into the frame of the horns itself.
The plasma horn tweeter can do 110db @ 1m max. It is 94db efficient and volume and crossover is adjustable on the unit to match with the rest of the system. I like them too, but I would love to see a more efficient one in the future to keep 100+ db efficiency of a good horn system.
