Hello,
I'm working on my DBII. I have just about finished the cabinet, and as such have started playing around with tuning. I'm using the Decware recommended woofer. The insert is working well in that I had to use some bar soap on the edges to make it easier to move within the box. I'm having a bit of a challenge tuning it by ear. When I sweep it with my audio generator I see that the lower end resonance is at about 40 Hz i.e. the fs of the driver, and another resonance between 150 180 Hz. I have read that most seem to set it when the insert is 1.5 inches above the bottom of the box. I find lots of air noise when it's in this location. I'm wondering if anyone has used this woofer and found the " sweet spot" to be a few inches above the port opening. Thanks in advance for your suggestions.
