This is a shot in the dark. I need either a schematic for the Altec Lansing ACS621 subwoofer or just some information. Two resistors (R29/R30) burned out on my sub and I need to know their precise values. Altec Lansing tech support is, of course, useless. (In fact, they told me they don't support any product that is out of warranty. Not much of an endorsement.)

hum; likely a LOW PASS filter
(meaning only low frequencies are allowed to get to the speaker)
you should also see a capacitor connected to the resister -- what's it
say on the side of it?
edit:
here's an online RC calculator to play with the values
edit#2:low pass filter to a subwoofer would usually set the cutoff Fq at 60cps.
