SVS 20-39PCi pulls 0W?

post #1 of 8
Thread Starter 
I have a SVS 20-39PCi subwoofer and hooked it up to a UPS. The UPS claims it pulls 0W even when it's producing bass. Can anyone explain why this is? It seems like it should be pulling something, even when it's not producing bass.

Yes the UPS works fine, I can connect a simple remote charger and it shows 2W when charging a remote.

This just proves how efficient the SVS amp is.

Maybe it pulls more than the meter will display, so it shows 0 instead of pegging the needle.

It's a 900W UPS.

Could it possibly be because the SVS plug isnt grounded, so the UPS isn't detecting it correctly?

The Sub may be pulling less than 1 watt at idle, so it may not be able to display it.

I don't know anything about electricity but try playing a sine wave(100hz?).

yeah play something with a continous sound, the burst of sound from movies may be too short for the meter to measure

Tried Sine Wine 50, 70, and 100 and all produced 0W usage. I touched the sub just to make sure it was producing the sound and not my speakers.

That is strange it should register something even in standby you would think 1 or 2 watts and definitely when heavy bass is playing most will say on their spec sheet
requires 300 watts or better draw.
