I want to hook up a low pass filter to a bass speaker we have.  I found a simple diagram on how to make one, but one of the two components aren't available around here- namely a load coil.  I don't have my cheat sheet with me but I know the numbers for the coil and capacitor are 113 and 14.4 (not sure which is which without looking it back up.) 

Now I found out I don't need a coil if I have a resistor, but I can't find a cheat sheet on the internet that tells me the Ohms I need for the resistor.  Does anyone know where I can find a chart showing resistor/capacitor pairs for a low pass filter?  Is there a way to convert a load coil rating to a resistor rating? 

At the moment the speaker is hooked to a 200 wat amp.  It may go to 400 down the road.  The speaker (a Bose Accoustic Cannon) should handle 600.   It has 8 ohms resistance.  I'm looking to filter out frequencies over 125hz with a 12dbl fall off. 

Yes, those wombats will always be with us.  Which explains (plus litigation) why ladders come plastered with warning stickers: "Don't set on ice patches!" "Don't reach out beyond the ladder!" "Don't use aluminum ladders in rainstorms!"

Recently in the news near us a fellow that couldn't get a lag bolt off of his car went inside for his shotgun and had at it.  Needless to say the bullet didn't succeed in loosening the bolt, but did succeed in loosening his nuts when it bounced off the car.  Ouch!!  Either  or .  Last I heard the docs were separating soup from nuts without specifying the likely outcome.  I'm sure you've heard of the Darwin awards.  I think if you die in the act of being a wombat you qualify--or if you lose certain abilities to propagate your wombat-ness can also qualify.

I've never done anything wombat-ish myself!
