My take, and I've heard them all.
Loudest to quietest list as follows:
Sceptres
everything else......
Way louder than the rest. Only the D&D's come even close, and they're down the dB chain quite a bit.
Want to set off car alarms a block away?
Want to instill the rath of your neighbors upon your person?
Want every cop in town to know who you are?
Want to be heard 10 minutes before you get there?
Sceptres.
