I think Jon Dahlquist was a mechanical engineer and may have been aware of the swamp of vibrations you refer to. The fact that part of his crossover though mounted on the top of the cabinet was a step ahead by not being hammered inside of the main cabinet. The fact that 4 of the 5 drivers were mounted on their own baffle boards would effectively reduce noise and clutter and cross pollination of resonance.
Jon once sent me a box speaker to audition and called me for an opinion. It was just okay. Months later I received the same oak speaker now finished in Nextel and with some flocking material on the front baffle..they sounded like a totally different design. He said everything was the same except for the 2 features I just wrote of. I think Jon was way out ahead of this peers. Tom
