Re: building a box for d6 12 diamond audios
Stay away from Diamond's vented design if you want sound quality or deep bass. It is tuned to 40Hz which is way to high for the D6s. I would suggest tuning as low as you can with the space available (low 30s to even mid to high 20s would be ideal).
I have a single 12" D6 in a folded transmission line enclosure. It has some amazing low-end and great sound quality. Not an output monster but is great for what I was looking for.
