Subwoofer power conditioner

Thank you all very much for your input.  I am a bit confused by spatialking's information and whether the power filter I found is suitable?  I found an APC AV C Type 2 outlet with let through voltage rating of / 40 volts (under 40 volts) and a surge energy rating of 1890 J (joules).  The product data sheet does not speak to amps.  The EMI/RFI Noise rejection is 55 dB.  I would use this product, if appropriate, as a dedicated surge/noise protector one per REL S/810 sub-woofer.  The subwoofer is rated at 800 watts and -6dB at 19 Hz.  

You could always contact REL and ask them what they recommend. Which REL did you go with that goes that low?

PS - I recommend Furman with SMP/LiFt as much better than just EMI/RFI protecting units.  Not only do they have superior surge protection, but the filtering starts much lower, below 10 kHz, which is well within the audible range.

I use a Furman as erik_squires mentions above for my REL subs.

I'm using a Niagara 1200 on a dedicated circuit for the 2 front JL F-113's. The other 2 are on the same dedicated circuit but since they are on the other side of the room, they are just plugged into a couple Furutech outlets.
