Vortech in a smallish cube

[lastlight]

in the video when the lights on the controller light up i assume this is when the pump is pumping. you can REALLY hear the pulses. would one of these in my livingroom be annoying? I didn't think these things were so loud you could hear each pulse?

I'm looking at one to center on the back wall of a 30x30x18 cube...

Thanks,

Brett
