This has led me to ask some questions about their other speakers, which I would expect are not inexpensive: 1) How do they get 98dB sensitivity out of the midrange and dome tweeter combination in the HC-14/15? 2) What are their "Trumpeteer R-200 and R-100 Wave Projectors" in the HR-200 and HR-100 cabinets? Does anyone recognize thse drivers? 3) Is that a Selenium driver in their He2 high efficiency cabinet? These don't look like the best quality drivers to me. I would expect a Pi 4 Premium or Professional system to be more suitable for the continuous high output required for an organ speaker.
