I'm placing my bets on a CLM or some other British-standard unit made in Canada. Darn, I just looked at the test schedules, what an inconvenient time to venture two hours out of town for. xD

The Tenri University pool turns out to have a twin setup! I noticed the perspective between the two pictures seemed off for them to be photos of the same unit, so I hovered over the spot on Google Earth and sure enough there are two towers, each one with a siren on top. I wonder as to whether that w...

Incredible that recordings and footage of these obscure beasts exist! I really love the multilayered wind-downs after each show; simply mesmerizing. Major kudos for being able to compile so much info on something we'd assumed for a long time now had been lost to history.

I know I'm a little late to the party, but kudos on the find! I agree with Uncommonsense, gems like these surface only once in a long while. Heh. Those photos were taken half a month before my second birthday. It's interesting to note one row of drivers on the Quadren effectively taking up two cells...

I do have a personal preference for single-tone 8-port sirens though, their wail and ambiance is elegant and especially spooky. I totally agree with your thoughts on the single-tone sirens. There's something frightening about a single low tone set to fast wail. As far as the ratios, it'd be a tie b...

Doesn't surprise me then. I thought their ATI sirens were doing fine, but I guess it goes to show. Hope Amherstburg isn't going through the same hassles with their system.

Here's hoping for a lengthy stay of the Thunderbolts, and if a replacement is in the works it'd be nice if a mechanical equivalent takes the spot. Now, I'm not certain on their holiday policy, but I sure was glad to be able to hear the beast go off on the 20th. Perhaps the sirens relegated to the de...

Oh gosh, that is heartbreaking! It sucked to hear of when they finally took the 1212s out a decade ago, but this seems like the final nail in the coffin for what was once a diverse system. There is a trio of Mods strung along the rail yard that the article may by chance be alluding to, but the fact ...

It's always neat to hear a siren with an odd ratio. That pitch is dizzying high!

Ha! Sounds like a Super Sirex. I'm sure the lower, single-tone setup carries considerably farther than the standard 10/15 ratio, but that shrill twin-tone howl is classic.
