In my first post about this subject the first paragraph referred to the DQ10's which were a break thru in in time aligned and phase aligned speakers. When Jon used separate baffles he may have only by chance hit upon a way to reduce unwanted vibration "drowning" the music. He partially achieved this again by taking the crossover out board. The DQ10's had wooden feet or an optional wooden stand.
The second reference speaker was the DQ9 when Jon applied the Nextel to block the bad sound of MDF and then putting a flocking material on the front baffle he succeeded in remaking this speaker. Maybe these were all accidental and with no clear cut understanding of why but the outcome of vibration reduction was made more apparent by Jon Dahlquist. I can write about these speakers and materials because they made an impression upon me and gave me direction to pursue and better understand resonance control methods. Tom
