Re: Wilson Whisper
The Whisper is likely a solid unit. It is larger volume than most, so it is probably in the ballpark of 30-32DB reduction, and it is about the same weight as stainless suppressors while being titanium, so it is probably fairly durable too.
IE it has a faster cooling material, that is massive enough to absorb reasonably high amounts of temperature input without over heating.
Now that the prices have shifted closer to reasonable given the titanium construction and Wilson brand name, the suppressor is probably a reasonable value. It was originally announced at an more optimistic price of ~$2200.
