Resun LP,,, Definetely queiter after connected to load or manifold.
Many people test noise pulling out of box and plugging in,,,, but true test is when it's hooked up under test.
I've dealt with many pumps in my time, when any other pump the same size of the LP is compared to the LP they never perform like the LP for volume output or quietness.
It's like every other pump out on the market has a output less than they state,,, or is LP punching out more than they state ??.
Pond one pumps are fairly quite, but the odd one seems a tad noisier, same size comparison to LP though is still is not as good as LP.
I've had all brands cook and break as much as each other for the brands I've tried anyway, about six roughly all up.
The true secret to a quite pump is to have a large manifold to sufficiently deliver air volume that it's trying to expel.
To many people have manifolds that are to small (even one they supply with pump is to small on larger models), and all the pipes diameter delivering the air throughout are usually to small,,,, some people go over board with diameters but there's no harm in that.
