 As I am sure you know better that I do, a sealed enclosure is the most forgiving of the classical enclosure styles. The Adire website recommends using the Tempest driver in a 2-5 cu.ft. sealed enclosure. I used the AJ Sealed Subwoofer Designer software (freeware of course), and calculated a Qtc=0.816, which is a little high but still very good, and F3 (-3 db point)=35Hz. From the response curve it appears that the -6 db point is at about 22Hz, which is good for my application.
Another consideration with down firing drivers is cone sag. In one of their technical papers Adire gives the formulas to calculate sag, and recommends that cone sag should be no more than 5% of Xmas. Plugging in the parameters for the Tempest driver I calculate 2.78% cone sag, which should be satisfactory. |
Did you ever replaced the drivers? If so, which one did you get? And about the crossover, did you direct into both coils or it got replaced.
Thanks
