Agreed on the adding mass and losing subjectively in the transient response department as Barry suggested. I wasn't suggesting a sealed box in hopes of achieving a true acoustic suspension system, but if you tune the woofer at say 40Hz and boost it by 12 dB at or below 40Hz the woofer will be unloaded and likely distort substantially. My thinking was that at least with a sealed box, you still have box loading on the driver to keep some of that distortion under control. This would really require modeling before committing too much effort into it.
Yes, Merry, Happy!
