The Sil Megaphones have a removable silencer dB killer insert that knocks the rumble down to around 85 dB. It's a pretty deep sound, and it still sounds really good (not as good as LOUD
). But even with the baffles in, they occasionally still set off car alarms. I put them in when I know I'll be out late, and don't want to overly disturb the neighbors when I'm coming home.
They have a slightly fatter profile than the DP conti replica megaphones, and they're shorter too.
