Hmmm, that may be.
Still though. If I run my Laing D4 at 12V in my office sitting on vibration deadening padding on the floor, I can still clearly hear the whine when sitting in the loungeroom, which is 25' away through two (open) doorways with the TV on during quieter lulls in the TV volume - as in whenever the TV goes quiet(ish), I can immediately hear the pump's whine.
Now how many people who own an Eheim 1048 (I do) can ever say that their 1048 is even one half as loud as that?
