I know what 1046 and 1048 Eheim pumps sound like - which made the
pump sound recording in that cooling-masters article very useful.
Bill, you mentioned that it was only "pretty quiet" (sorry - might be misquoting here). Did that mean "not dead silent"? - Is this recording representative of the sample(s) you've had your hands on?
Anyway, if this recording isn't misleading I definitely want one.
