What is the loudest electronic siren?

[SirenMadness]

I'm not in any way saying that speaker sirens aren't electronic nor that mechanical sirens don't run on mechanical means. Yes, speaker sirens do produce an electronic sound, but there are more electronics there than those that produce the sound - there are also diagnostics and lots of other stuff. Same with most of today's mechanical sirens - they have electronics controlling them. The thing is, I just like to refer to them "electronics" as speaker sirens!

Also, here is the design of mine that I was talking about earlier.
This is just a crude drawing, but you may get the overall picture. There are rows of drivers each focusing their sound down towards this cone at the bottom; the sound gets projected there. Voice capability may suffer due to distortion, but this should be a powerful siren.

The Chrysler Air Raid Siren (second generation), or known as the Chrysler Bell Victory Siren (first generation) was an outdoor warning siren produced during the Cold War era that had an output of 138 dBC at 100 feet (30 m).
Built during the World War II and Cold War era from 1952-1957 (second generation) by Chrysler, its power plant contained a newly designed FirePower Hemi V8 engine with a displacement of 331-cubic-inch (5.42 l) and producing 180 horsepower (130 kW).[1]

Its six horns were each 3 feet (0.9 m) long. The siren could be heard from a distance of 20 to 25 miles (32 to 40 km) away and had an output of 138 dBC (30,000) watts. They were 12 feet (3.7 m) long, built atop a quarter section of a Dodge truck chassis rail, and weighed an estimated 3 short tons (2.7 t).

In 1952, the cost of a Chrysler Air Raid siren was $5,500.00.[1] (Approximately $43,966.48 in 2009 dollars.[2]) The United States government helped buy sirens for selected state and county law enforcement agencies around the country. In Los Angeles County, six were placed around key locations of populated areas, and another ten were sold to other government agencies in the State of California. These "Big Red Whistles" (as they were nicknamed) were only ever used for test purposes. Some were located so remotely that they deteriorated due to lack of maintenance.

The main purpose of the siren was to warn the public in the event of a nuclear attack by the Soviets, during the Cold War. The operator's job was to start the engine and bring it up to operating speed, then to pull and release the transmission handle to start the wailing signal generation. The Chrysler air raid siren produced the loudest sound ever achieved by an air raid siren

Wow! That's pretty loud for electronic sirens! I wonder what the DB rating is for an EOWS612.

sorry to bump such an old comment 2dbs below and 812

Um, the Chrysler isn't electronic. Hell it doesn't even run off electricity at all, it's a fully independent mechanical siren.

I would say the current loudest siren in production is either the wps-4000-4, or the wps 2910.
