Hey Tre',
The Duntech Princess has been unavailable in the US for years now and didn't sell in big numbers when it was. So not likely many Inmates are familiar with them.
It was a 5-driver, 3-way design in a very large sealed cabinet. It followed the D'Apolito array design. John Dunlavy favored time/phase coherent designs.
The Princess crossover PC board was mounted on sliders and could be accessed from a panel on the back of the cabinet. An audio buddy with pretty deep electronics experience brought over a 30 or 40 watt stereo tube amp he'd built to audition on my speakers. He suspected that should be adequate for a 90-91 dB speaker. His amp fell flat, it was lifeless in driving the speakers. So he ask about the crossover design. I didn't know enough to explain it so I opened the back to show him the board. When he saw the crossover he joked that if it had a transformer added it should be able to power the speakers. Sorry I don't have a photo to share.
