Curious lang, do you guys check the frequency rating of these horns? I mean, when you say matinik, malalim, malakas - how can you prove that objectively to other members reading the thread?
I've had the chance to try 420Hz vs 400Hz Bosch horns, the 420Hz was stock for Hondas while the 400Hz is for my MB (both high tone horns). The lower tone horns were similar, but in combination, the higher tone horns gave the Honda (420Hz) a "thinner" sound than the Benz, which has the 400Hz horn.
At the junkyard I've found a horn that has 375Hz, in between the high and low tones. I haven't had the time to check it so I hope it turns out good. It's also Bosch by the way.
