Very interesting discussion. I have taken a close look at Marco's horns and am thinking about using them in a horn installation. I plan to use the TAD 4003 from, say, 1 to 8 kHz, and a tweeter above that. I would love to use horns below 1 kHz but wil...

Hi Romy, thanks for the links. Did you try any other TAD's than the 4001? Like the 2002 1" device or the 4003? The ET-703? Did you utilise the 703 to cover the top octave and a half and suppress the resonance? It's certainly my experience that the...
