I bought the Frigidaire 46-Bottle one from Lowes last night, it has 30 day no Q asked 100% return policy.
Unboxed it this morning, plugged it in, set the temp for 38deg f.
My Radio Shack db meter says 51db or less, there is a small higher freq "humm" from it though, not bad but louder than the older stand up refrig/freezer unit its replacing....
When I next hook up REW for my acoustic readings (with Berringer8000 mic) I'll take a RTA and see what freq and "real" db it is at.
For now, it's not annoying at all but we'll give it 2 weeks time before I pass judgment.
It's gonna replace this still working stand up refrig/freezer.
(we also got a full size Freezer that is going in the utility room, which is sealed off from basement)
which as you can see from this older pict (pre-acoustics panels), there HT does NOT have Double French Doors just yet, so I'm senstitive to sound level, just like you guys with the open basement HT are....
