Dayton DC160 as a sub?

Hi Matt-

I ran the numbers through a spreadsheet simulator (excelsub.xls). I used the specs for the 4ohm version (DC160S-4). The T/S params were slightly different than posted.

The main limiting factor is the small xmax. In a 15l ported box (~.5 cu ft, tuned to 42.6hz), the input power before reaching xmax is only 13 watts. In a tiny sealed box (3.8l, ~.14cu ft), power handling is slightly better, at 20 watts.

In car SPL (with cabin gain) was 105 db @ 47.8hz with 13 watts for the ported box; with a rapid decrease in spl below that.
For the sealed box, max spl was ~101 db @ 110hz; dropping smoothly to 95 db @ 20hz. (20 watts input)

The sealed box is self-limiting the drivers' excursion. The ported box needs some sort of hi-pass (subsonic) filter to keep the driver from bottoming out. (35hz Q=.707 would work nicely).

This is where I snagged the cool spreadsheet:
